PROJECT DESCRIPTION:

The plaque method for assay of infectious virus in natural water will
be examined in order to determine the effects of virus particle aggregation.
Physical assay by quantitative electron microscopy will be employed to determine
the number of single viruses, pairs, triplets, etc., present in water suspensions
of the virus. Correlation of these physical data with plaque titer of virus in

different states (degrees) of aggregation will be sought for several viruses com-
monly found in water.

Previous work with large viruses indicates that the degree of clump-
ing may alter the plaque titer by one or more orders of magnitude particularly
if the virus has been partially degraded. Multiplicity Reactivation, evidenced
through clumping, will be examined. A major part of this project will be the
adaptation of physical assay methods, now used with large viruses to similar
work with the picorna viruses. When this has been accomplished it will be
possible to proceed with direct observation of virion aggregation in natural
water, as compared with optimum buffered saline solutions commonly used in the
laboratory. Rational interpretation of plaque assay of such water suspensions
can then be made with full consideration of virion clumping.

PROJECT DESCRIPTION:

Shagawa Lake, which borders the City of Ely, Minnesota, and receives its
wastewater discharge, is in a state of advanced eutrophy. The objective of
this project is to demonstrate that removal of essentially all the phosphorus
(residual phosphorus levels of <0.05 mg/l) from the City of Ely's municipal
wastewater, in conjunction with efficient overall treatment, can restore a
eutrophied lake.

The City's existing 1.5 mgd high rate trickling filter plant has been
upgraded, septic tank drainage has been diverted to the treatment plant, and
new tertiary wastewater treatment facilities following the existing City
plant have been constructed. The 1.5 mgd tertiary facilities consists of flow
equalization, two-stage lime clarification, dual-media filtration, and chlorina-
tion. Mixed primary/secondary sludge and chemical sludge are disposed of via
gravity thickening, vacuum filtration and trucking to sanitary landfill.

Wastewater Research Div. COMPLETION DATE: 6/30/77

PROJECT DESCRIPTION:

The primary difficulty encountered by the City of Bend in it's attempt to
provide complete sewer service by 1980 is one of economics. Conventional sewers
would be prohibitively expensive to the residents of the community, even with
Federal assistance. Therefore, usé of pressure and/or vacuum (See Figure 3)
sewers presents an opportunity for considerable cost savings. These savings
would accrue from the fact that such systems are laid to a depth dictated only
by frost penetration, which in the Bend area is approximately 36 inches.

In addition, these systems utilize small-diameter plastic sewer pipe which may be,
laid in a manner which requires less time and effort, resulting in further

cost savings. Another advantage of these systems is their "tightness," which
essentially results in the elimination or minimization of infiltration. Reduced
infiltration means that the hydraulic capacity of treatment and pumping facilities
is reduced significantly on a flow per capita basis.

If either or both of these sewerage methods can be successfully demonstrated
prior to the development of the plan to sewer the community, their use in many
areas of the City has the potential to drastically reduce the overall cost of
and minimize the disruption caused by sewering the community.

The proposed study entails the design, construction, and operation of
parallel vacuum and pressure sewer systems, each serving from 10 to 20 homes,
in an area where the construction of conventional gravity sewers is prohibitively
expensive and potentially dangerous. The construction requirements and costs
will be carefully documented and compared to similar information on gravity
sewerage, The operation and maintenance needs will be documented and wastewater
characterizations will also be made to provide further comparative data between
these systems and with conventional systems.

of ozone and ultra violet light as possible disinfectants of drinking water for
small community water supplies.

The proposed demonstration project will involve the installation of ozone
and ultra violet light disinfecting equipment on existing small water systems
in Grand Isle county. The bacteriological quality of the raw water, disinfected
water and water at the consumers taps will be closely monitored to ascertain
the effectiveness of the disinfection and to determine if the bacteriological
quality can be maintained throughout the distribution system.

Field studies will be conducted at seven small water systems in Grand Isle
County. All systems serve less than 500 people and all use a common source of
supply, Lake Champlain. Two systems provide filtration and chlorination, four
provide chlorination only, and one provides no treatment or chlorination.

Ozone and ultra violet equipment will be installed to provide for evaluations
on systems with and without treatment and to compare the results with systems
which chlorinate and those which provide no disinfection.

Weekly samples will be collected from each system of the raw water, treated
and/or disinfected water, and water at three points in the distribution system.
Routine analysis will include total coliform, fecal coliform and standard
plate count as well as selected chemical and physical parameters pertinent to
disinfection (pH, temperature, turbidity, ozone residuals, dissolved oxygen).

Ba, Se, Hg, Co, Mo, As, B, and viruses by select waste treatment processes
will be examined. Raw waste waters will be characterized for heavy metals
content. The fate of these heavy metals will be determined as the waste
water is treated using a combination of the following processes: activated
sludge, dual media filtration, carbon adsorption, chemical treatment and
chlorination. Virus studies will be concentrated in the tertiary treatment
loop.

Studies will be performed on full scale treatment processes and pilot
scale processes to arrive at a treatment train which will be suitable for
water reuse and will effectively remove the heavy metals.

PROJECT DESCRIPTION:

A 700-acre drainage area in the City of Racine, Wisconsin, has a
total of 53 outfalls on a four-mile stretch of the Root River. Of
these outfalls, 17 are separate storm sewers and 36 are combined
sewer overflow relief points. Several outfalls will be intercepted
and the flows directed to five riverside treatment units, of which
three will treat combined sewage, one will treat storm water only, and
one will treat both. The untreated excess combined sewage and urban
runoff produce high shock loads on the receiving water during rain
events or snow melt. Rather than separation of the combined systems,
an alternate of treating the sewage by screening down to 200 microns
then flocculation and flotation with pressurized dissolved-air will
be demonstrated. There will also be verification of a recently developed
combined sewer/water quality mathematical model.

PROJECT DESCRIPTION:

The effect of various additives on the improved dewatering of activated
sludge is being determined and the surface properties of the additives
characterized in order to arrive at a mechanism for flocculation of activated
sludge particles. The primary additives investigated are fly ash and 3
sludge incinerator ashes. All four ashes have high surface areas, 1.7 to
17 m//g, a hydrophilic surface and a high concentration of water soluble
salts. Since the presence of salts and a solid surface complicates the
interpretation of experimental results, a series of experiments were devised
where either salts or solids alone were added to the activated sludge for
settleability measurements. The solids consist of the washed ashes themselves,
as well as two silicas, two carbon samples and magnetite, which contains
high surface areas and exhibits different surface properties. The salts
consist of the washings obtained from the ashes and a number of inorganic
salts and ionic polymeric surfactants.

All four ashes greatly increase the rate of settling of activated
sludge in the order Tahoe > Kansas > Millcreek > Beckjord. Repeated washing
of the ashes has the effect of decreasing the rate of settling and changes
the relative efficiency to Kansas> Millcreek >.Beckjord > Tahoe. The
hydrophilic silica carbon black and magnetite greatly increase the rate of
settling while hydrophobic silica and graphon have very little effect.
Halide salts and only the cationic polymeric surfactant are capable of
increasing the rate settling. A dual mechanism, which was based on coulombic
interaction between sludge particles and solid additives, is proposed.

The final report is being reviewed.

INTRODUCTION

The research and development programs of the Municipal Environmental
Research Laboratory in Cincinnati span the areas of wastewater, water
supply, and solid and hazardous wastes. MERL was organized to provide a
multimedia focus for these areas in approaching the pollution control
problems of municipalities and other large public institutions. Since
extramural work includes many of our larger and more prominent projects,
e.g., demonstrations, publication of these summaries of active extramural
research tasks serves to highlight a most significant portion of our
research effort.

The Wastewater Research Division develops cost-effective pollution
control technology, methodology, and systems for treating liquid municipal
wastes, and for handling the resulting sludges. In addition to biological
and physical-chemical treatment technology, WRD is concerned with upgrading
of existing plants, pollution control measures for storm and combined sewers,
and the dewatering and disposal of municipal sludges. Their work extends to
supporting areas such as cost studies, environmental management, water reuse,
process instrumentation, and operation and maintenance of existing plants.
The principal current mandate of the WRD derives from the 1972 amendments
to the Federal Water Pollution Control Act, which set up a series of
escalating plant performance standards for pollution control and prevention
extending through 1985. A major area of impact of WRD research is on the
multibillion dollar construction grant program sanctioned by the 1972 Act.

The Water Supply Research Division determines the occurrence of con-
taminants in water supplies, and develops and demonstrates water treatment
and control technology. The WSRD concerns itself with the removal or
control of organic, inorganic, and microbiological contaminants, as well
as with the problems of water quality deterioration during storage and
distribution, and with economic analysis and other water supply management
questions. WSRD works with the health effects research programs of EPA
to develop information necessary for the formulation of defensible drinking
water standards. The principal current mandate of the WSRD is the 1974
Safe Drinking Water Act.

The Solid and Hazardous Waste Research Division develops and demon-
strates new and improved technology and systems for solid and hazardous
waste management. The SHWRD evaluates processing technology (including
both collection and transportation) for either disposal or resource
recovery, and socio-economic effects associated with these areas. Dis-
posal technology, especially sanitary landfills, is also evaluated,
together with related environmental and socio~economic effects.
Hazardous wastes are a prime area of concern, and here the emphasis is
on characterization of such materials, e.g., pesticides, organic sub-
stances, metals, as well as on their processing and disposal. The
current legislative mandate of the SHWRD is the Resource Recovery Act
of 1970.

with an IBM System 7 process control computer on the pilot physical-chemical
treatment system and to evaluate an analog control system in the three-stage
activated sludge treatment in the EPA-DC Pilot Plant. Closed and open loop
analog response data developed by the EPA on an existing analog control system
is being used by the District of Columbia and IBM to develop digital control
algorithms for four feed-forward feed-back control loops and three feed-forward
loops in the physical-chemical system. The feed-forward feed-back control
loops are flow-proportional pH-error control of lime and co, in lime treatment,
and CL, in pH reduction, and, in breakpoint chlorination, mass-proportional
cl, and mass-proportional pH-error control of NaOH.

The feed-forward loops are flow-proportional control of FeCl, and sludge
wasting in the two-stage lime treatment process. To date, the control
algorithms have been developed and confirmed by IBM with simulation techniques.
The system 7 computer is installed and on-line evaluation of the control
systems is proceeding. The evaluation of the analog control system in the three-
stage activated sludge system is beginning and will be used in a later study
to develop digital control of portions of the three-stage activated sludge
system.

selected from such candidates as cotton gin trash, peanut hulls, and bagasse.
Hardware of this general type has been under development by Georgia Tech for
several years and the results have been very encouraging, based on laboratory,
pilot, and near-full scale hardware tests. Although the system has already
been scaled up to commercial size in an operating plant pyrolyzing wood waste,
a few additional hardware refinements are indicated for processing harder to
handle wastes such as those listed above. The study will include some fourteen
or more instrumental test runs with complete data analysis.

PROJECT DESCRIPTION:

The objective of this project is to demonstrate a new, non-intrusive,
low cost, reliable, passive measurement system capable of monitoring flow

for the highly variable conditions encountered in storm, combined and sanitary
sewers.

The system's concept involves a proprietary technique of utilizing the
sound emission resulting from the interaction of fluid flow with a discontinuity
of a solid surface. In this application to sewer flow, a discontinuity is
any inherent change in the sewer cross-section, slope, or direction that
can significantly affect the flow area or direction.

The first phase of the project will include laboratory investigations
directed to optimize system design details for sewer installations, and
analyses which will relate theory and test data to measurement system
design objectives and applications. A short duration field test preview
will be conducted in the contractor's facilities, using breadboard equipment,
to exemplify the nature of output data to be obtained in a much more extensive
field test program scheduled for a second phase effort.

PROJECT DESCRIPTION:

A prerequisite for effective control of storm runoff pollution is a
reliable method to predict the quantity of the storm runoff. The time distribution
of storm runoff from an urban drainage system depends on the areal and temporal
distributions of the intensity of the rainfall, the frequency of the rainstorm,
and the physical characterictics of the drainage system. Numerous methods have
been proposed to evaluate urban runoff from rainfall. Many have been accepted
for engineering applications while others need yet to be tested and verified.
The objective of the proposed investigation is to identify the best method or
methods on the basis of the design as well as operational viewpoint and to
recommend the selected method or methods to engineers for applications. This
objective will be achieved by comparing the methods on a common basis by applying
them to a selected urban drainage basin under identical rainstorms covering a
sufficient range of rainfall intensity, duration, and frequency. Steep slope
sewer hydraulics will also be investigated.

PROJECT DESCRIPTION:

The objective of this project was to operate a transportable advanced
waste treatment plant of approximately 75,000 gpd capacity that will
satisfy the treatment efficiency recommended by the Potomac River Enforce-
ment Conference for 1980 in Zone 1 of the River. However, extensive damage
to the equipment and site took place on June 22, 1972 when Hurricane Agnes
hit. As a result, the project was terminated. The facility was to have
been operated for a 12-month period to evaluate its dependability, efficiency,
operational characteristics, and its economics.

The approach to meet these strict effluent standards (5 mg/l BOD, 2.5
mg/l nitrogen, 0.2 mg/l phosphorus, and trace amounts of suspended solids)
was to have been made through a combination of physical, chemical, and
biological treatment. The planned treatment scheme was flow equalization,
chemical clarification, biological nitrification (activated sludge), upflow
columnar denitrification (with methanol), pressure filtration, and chlorina-
tion.

PROJECT DESCRIPTION:

Purpose of the project is to evaluate the operational worth and environmental
aspects, if any, of adding combustible solid matter to wastewater plant sludges
and filter cakes, as off-sets to part or all of the fuels conventionally used
in sludge incineration practice. Impending shortages of natural gas and fuel
oil create the sense of urgency in this work. Low-sulfur coal and combustible
solid wastes will be utilized as admix materials in various test sequences.
Wastes to be tried include shredded combustibles from refuse, in pelletized
and loose form, wood chips from urban tree-trimming, shredded tires, and
industrial combustible wastes. A full-scale multiple hearth furnace in a
modern wastewater treatment plant will be used. Applicability to other
incinerators of the 200-plus total in United States' communities will be
assessed. Assay of stack gases, after scrubbing, will include relevant

chemical properties of public health significance. Scrubber drainage and
ash will also be assayed.

PROJECT DESCRIPTION:

Because of the rapidly increasing cost of crude oil and the potential
decrease in the availability of methanol and other organic chemicals used
in wastewater treatment, it is desirable to seek alternative methods of
denitrification. The overall objective of this project is to evaluate
the microbial kinetics, and to assess the process feasibility of auto-
tropic microbial mediated denitrification using sulfur electron donors.
This will be accomplished by (1) preliminary delineation, via batch culture
experiments of metabolic and environmental requirements of sulfur oxidizing
bacteria; (2) evaluation of continuous culture kinetics such as temperature
and pH; and (3) evaluation of some non-kinetic factors, e.g. process
configuration, physical form of sulfur, effluent quality.

PROJECT DESCRIPTION:

The principal objective of this project is the development of reliable
techniques consistent with the basic simplicity of lagoon operation for
removing phosphorus and unoxidized nitrogen from lagoon effluents. Two
in-cell injection points will be evaluated to determine the potential of
alum addition for efficiently removing phosphorus from wastewater being
processed in a three-cell combined aerated faculative lagoon. A sidestream
of effluent from the last cell of this test lagoon will be diverted through
a plastic-media trickling filter tower to evaluate the potential for achieving
consistent nitrification with this type of second stage biological treatment.

The secondary objective is the acquisition of reliable long-term data
from well designed and well operated three-cell combined aerated/faculative
lagoon not receiving alum addition which will be operated in parallel with
the test system and serve as a control. Assessment of the effect of alum
addition, not only on phosphorus removal, but also on suspended solids and
organic removals and determination of additional costs and operating require-
ments necessitated by the nutrient control procedures.

PROJECT DESCRIPTION:

The purpose of the study is to evaluate the relative merits of using these
substances, once determined, as an alternate to the popular currently used
deicing chlorides. The study shall be undertaken from-the point of view of
finding an economical hydrophobic anti-icing/deicing agent which can be placed
on or within pavement surfaces (with lasting residual effectiveness and/or
low cost of material and reapplication) and that would not have irreversible
harmful effects on the environment.

While a specific substance which can fill pavement anti-icing/deicing
requirements has not yet been identified, there are a number of existing
compounds which should be tested before new research is begun. These compounds
are all characterized by their ability to form a fairly strong bond to a surface
while leaving no available bonds for water molecules, thus "repelling" any water
that comes in contact with it. There are three major classes of compounds;
Cationic Surface Active Agents, Organo-Flourochemical Compounds, and Organo
Silicone Compounds. Fatty-quaternary-ammonium compounds, a subgroup of the first
class listed above, might be particularly suitable. Such a compound, when
dissolved in the proper solvent(s), could be sprayed on the road surface producing
the desired film. This film would adhere to the road because the positively
charged road surface. Although such a film would repel water its wearlife
cannot be predicted easily without testing. A contract continuation will
optimizé the best substances and perform in situ testing in a northern climate.

PROJECT DESCRIPTION:

The treatment of leachate from many landfills in the United States is a
practical necessity. Research presently underway is designed to give quick
answers to the question of how to treat this liquid, since no lab, pilot, or
field-scale data is available. A more detailed study is needed to determine
process kinetics, the nature of the organic fraction of leachate, and the
degree of treatment that may be obtainable using conventional wastewater treatment
methods. In addition, other methods of removing pollutants from water are being
studied because of small volumes and the vast range of contaminant concentrations
and flow rates. This contract was awarded in June 1972 and results are not as
yet available. The final report, due in September 1974, should provide the tech-
nical data needed to rationally design on-site leachate treatment schemes.

of municipal activated sludge plants. This would be accomplished by disrupting a
portion of the microbial cells in the return sludge releasing enzymes from within
the cells directly into the wastewater and eliminating the rate controlling action
of the cell wall-plasma membrane barrier. These laboratory experiments were con-
ducted with bench-scale activated sludge waste treatment units, and the disruption
of microbial cells in the sludge was accomplished by use of a sonic oscillator.
Degradation rates of a number of specific organic compounds were studied in units
receiving regular activated sludge or varying proportions of disrupted sludge.

study, via controlled experiments, of the parameters governing the comminution
of size reduction of the heterogeneous mixture called municipal refuse can be
performed. This laboratory contains a 10 ton/hr. hammermill which has been converte
into a research tool. Hopefully, these studies will enhance the understanding
of the mechanisms involved in the size-reduction of refuse. Adaptability of pre-
vious analytical comminution theories to refuse are being considered so that compu-
tation can be made for size distribution and power requirements. Fundamental data
on size distribution of ground refuse and compression and tensile strength of
various refuse components as well as complete packer truck and ground refuse is
being measured. Energy requirements for various degrees of aluminum can shredding
have also been measured by means of controlled laboratory experiments. These
experimental data are vital to the establishment of the emerging technology of
refuse comminution. They also form an integral basis of a concept and plan for
the development of an apparatus, specifically for refuse size reduction.

of Lake Onondaga caused by enteric organisms in combined sewage discharge.
The treatment proposed is fine screening and oxidation/disinfection at selected
stationary, sequential, microstrainer and high speed rotary. There will also
be a solids/liquid separation utilizing the swirl separator. Disinfection has
been evaluated utilizing gaseous chlorine and chlorine dioxide generated on site,
by a new and improved technique. A final report, EPA-670/2-75-021 entitled,
"Bench-Scale High-Rate Disinfection of CSO's with Chlorine and Chlorine Dioxide,"
has been published. Dosage, points of application, aftergrowth, and other factors
in kill efficiency, will be carried out. A special virus disinfectant study will
also be included in the project. A supplement to this grant entitled, "Nutrient
Removal Using Existing CSO Treatment Facilities", will test/evaluate the feasi-
bility of nutrient removal with additional process units at a full-scale combined
sewer overflow treatment demonstration site in Syracuse, New York.

Alum will be fed at the proposed filter inlet and the alum flox will be
allowed to penetrate into the anthracite media which will affect phosphate
removal. Furthermore, the ammonia nitrogen will be reduced by the zeolite
media at the bottom layer of the filter bed. The system is expected to have
80% of nutrient removal efficiencies.

Regeneration of alum sludge and exhausted zeolite as well as Badger solids
monitor will also be evaluated.

Another supplement to this grant will conduct in situ test on SCS developed
instrumentation (automatic sampler and TOC analyzer). In order to complete the
objectives of the overall project, ten (10) additional combined sewer overflow
events will also be monitored under this supplement.

PROJECT DESCRIPTION:

The objective of this research project was to evaluate and demonstrate
potential methods for upgrading the performance of high-rate trickling filter
systems.

Three major investigations were carried out using facilities of the joint
University of North Carolina/City of Chapel Hill municipal treatment plant:
(a) Single-stage trickling filter operation was compared with two-stage trick-
ling filter operation in pilot units with equivalent volumes in both systems.
(b) Overall system removal was analyzed in the full-scale plant as a function
of final settling tank overflow rate. (c) Alum addition to the final clarifier
was evaluated as an upgrading technique in the full-scale plant.

Data from these investigations indicate: (a) In any treatment plant with two
or more trickling filters, provisions for series or staged operation of the
filters will produce significantly better treatment than operating the filters
in parallel as single-stage units. (b) Funds spent on additional final settling
tank capacity is perhaps the most economical method of improving performance of
trickling filter plants. (c) Controlled dosing of liquid alum just ahead of the
final settling tank yielded the greatest improvement in treatment efficiency of
all methods studied on this project and can upgrade the performance of a high-
rate trickling filter plant from marginal levels to one comparable with a well
operated conventional activated sludge plant.

heavy metals uptake by plants) of land disposal (trenching) of various sludges
(raw primary-activated, digested primary-activated, and mineral (alum) addition
or lime treated sludges) in both greenhouse and field scale studies and (2) to
evaluate field scale trenching application techniques for limed raw and digester
sludges at very high loadings per acre (over 200 tons/acre). Greenhouse studies
in sandy soils simulated trenching techniques and revealed nitrogen and organic
movement through four feet of soil. In the field studies, initiated in May 1972,
raw and digested sludges were limed to pH 11.5 to stabilize the sludges, success-
fully placed in trenches (2'-4' deep) and covered with backfill. Ground water
samples were periodically withdrawn from field wells to determine movement of
pollutants into the ground water; the area between trenches was planted with
crops and trees. The results through November 1972 revealed essentially no
movement of pollutants into the ground water and no odors or other esthetically
objectionable effects and successful plant growth. The project is a cooperative
study of the U.S. Department of Agriculture, the Maryland Environmental Services
and the District of Columbia Department of Environmental Services.

PROJECT DESCRIPTION:

The objective of this research is to forecast the solid wastes generated by
U. S. households from now through 1985. Emphasis will be on forecasts of the
residuals from consumer purchases of food, publications, entertainment materials,
and clothing. Other appropriate candidate for inclusion into the household solid
waste flow are household appliances which are ultimately discarded, such as electric
irons, television sets, and toasters. Other consumer purchases, such as automobiles,
large appliances and furnaces, may be more appropriately treated as specialized
waste flows rather than household waste flows as they are typically disposed of
by the vendor replacing them. The results of this research will make it possible
to increase the effectiveness of future disposal and resource recovery technolo-
gies and incentive strategies, which are largely dependent upon the composition
of the waste stream to which they are applied.

Available consumer spending forecasts will be reviewed, identifying those
products that may be expected to have waste management consequences. The
results of these forecasts will be used to identify the economic sectors which
produce these goods purchased by consumers. Input-output models will be used
to identify the inter-sectorial relationships associated with each purchased
good. Then with respect to these sectors and the goods produced and consumed,
substitution analysis will be conducted to determine when one raw material will
substitute for another (e.g., synthetic for natural fibers) or one produce will
substitute for another (e.g., pre-packaged and precooked food for raw or unpre-
pared food). The substitution analyses will account for changes in technology,
cost and product mix.

PROJECT DESCRIPTION:

The major objectives of this project are to demonstrate that oxygen aeration
can be applied without expansion to upgrade an existing modified air aeration
activated sludge plant from 75% + treatment to 90% + treatment and that a mole-
cular sieve oxygen gas generation unit can be successfully integrated into the
total process to supply oxygen requirements.

One 20 mgd bay was isolated from 15 other similar bays of New York City's
Newtown Creek modified aeration plant and converted to the Union Carbide sub-
merged turbine-sparger oxygen aeration option. A 15 ton/day Pressure Swing
Adsorption oxygen generation plant was installed along with a liquid oxygen
backup supply system. After system startup and shakedown, a one-year demonstra-
tion was commenced in mid-September 1972.

Early results indicate that effluent BOD, and suspended solids concentrations
of approximately 10 and 15 mg/1, respectively, are being produced in the oxygen
test train at a constant flow of 20 mgd (equivalent to an aeration detention time
based on raw wastewater flow of 1.4 hours). Corresponding F/M and volumetric
organic loadings approximate 0.7 1b BOD. applied/day/1b MLVSS and 150 1b BOD
applied/day/1000 ft’, respectively. In contrast, the remainder of the plant
(the 15 unconverted bays) is producing an effluent with average BOD, and sus-
pended solids concentrations of about 30 and 40 mg/l, respectively, at a nominal
aeration based on raw wastewater flow of 2.5 hours. Oxygen train performance
is currently being evaluated under diurnal flow variations. Subsequent phases
will determine the ultimate organic and/or hydraulic loading capacity of the
oxygen train and phosphorus removal efficiencies possible via mineral addition
to the oxygen aerator.

from a pilot stormwater treatment plant will be pumped to the pilot lake at
variable rates to simulate flows and detention times predicted for the larger
lakes. The project is comprised of three basic areas: 1) Application and
verification of EPA's SWMM for straight non-sewered urban-runoff. 2) Piloting
various stormwater treatment and control techniques, e.g., porous pavement, screening,
swirl separation, high rate filtration, biological oxidation, carbon adsorption,
chlorination/iodinization, and ozonation. 3) Establishing required treatment
levels for pilot lakes. This project will develop and demonstrate an environmentally
acceptable water management system for stormwater and dry-weather flows. The
system will include reclamation of urban runoff for recreational and aesthetic
purposes and dual dry and wet-weather flow treatment facilities. Thorough
ecological effects of various biocides, nutrients, and disinfectant residuals
in runoff will be measured. The important conservation philosophies of con-
sidering urban runoff as a benefit as opposed to a wastewater, along with the

conditions; to determine the effect of solids production and wasting on the nitri-~
fication and denitrification; and to determine the supplemental methanol require-
ments for complete denitrification. One single-stage system to be used employs
alternating periods of cycling dissolved oxygen in which the D.0. varies from
above 2 mg/l to essentially zero in a reactor operated at F/M ratios of 0.15 to
0.20 1b of BOD/1b of MLVSS/day. The cycling D.0. permits alternating nitrifica-
tion and denitrification by the activated sludge mass. Mixed liquor from the
discharge of the reactor is recycled to the reactor influent to allow the BOD
of the wastewater to serve as the carbon source for improved denitrification.

The system includes an optional (1 hour detention) denitrification basin for
methanol denitrification before the gravity settler. A second system to be
tested is a plug flow reactor with aeration at the front and back sections of
the reactor and an anaerobic section in the middle. Operational parameters will
be similar to those of the complete mix system with air supply on a time cycle.

The objective of this grant proposal is to develop/optimize a novel acid
hydrolysis process for the conversion of waste cellulose into glucose. Under
Phase I, a study would be conducted to develop and optimize physical and chemical
pretreatments for waste cellulose which would be technically and economically
superior to present practices for maximizing the glucose yields. Phase II
which is to be conducted concurrently with Phase I will concentrate on develop-
ment and optimization of a novel acid hydrolysis process which is based on
exposing an acid treated waste cellulose at ambient temperature to optimal
acid hydrolysis temperature by contact with superheated water or steam.

This basic research program could lead to development of a viable acid

hydrolysis system for production of glucose and its subsequent use as a feed-
stock for the production of ethyl alcohol.

PROJECT DESCRIPTION:

The objective of the research program is to constructively couple two
environmental problems, disinfection and treatment of sewage sludge and disposal
of nuclear waste materials. Successful coupling could lead to a mutually
beneficial solution, the utilization of nuclear waste products in the disinfection
and treatment of digested municipal ‘sewage sludge.

For ‘several years Sandia Laboratories has conducted studies on the use
of simultaneously applied heat and ionizing gamma radiation (thermoradiation)
for biological inactivation of viral and bacterial systems. More recently the
studies have been expanded to include a parasite system. These studies show
significant promise due to the inactivation synergisms exhibited by thermo-
radiation and the studies have been recently pointed toward investigation of
thermoradiation for disinfection of sewage sludge using reactor waste fission
products (e.g., Cs). If this technology can be successfully transferred
to sludges, it could provide a cost-effective alternative for sludge disinfection
and treatment and also for the beneficial utilization of intermediate-life
radioactive waste isotopes. The emphasis of the research program ison the
disinfection of liquid digested sludge. The joint program will draw on prior
studies to continue the research.

The 137¢6 necessary for a dynamic system (heat and radiation pulse in
a singlespass flow-thru system) is installed and in operation in Sandia's
Gamma Irradiation Facility. This system is being used to study effectiveness
of thermoradiation on the three pathogens of choice, polio virus, coliform
bacteria, and the Ascaris parasite. The results will guide the design of
the pilot plant where additional studies will be completed on not only the

biological, but also the chemical and physical characteristics of the digested
shudge. Also, tests with the 0.16 liter batch thermoradiation unit, us‘ing

Cs’are continuing, to guide optimization for disinfection of municipal
wastewater sludges.

PROJECT DESCRIPTION:

There are eight objectives to be met. Determine the effect of: 1) Varying
moisture regimen on production of gas and leachate; 2) Temperature on gas and
leachate production; 3) Wastewater treatment plant sludges on solid waste decompo-
sition; 4) pH control on solid waste decomposition; 5) Premature wetting; 6)
Hazardous liquid and sludge and their fate; 7) Determine the survival of polio
virus; and 8) Determine the settlement rate in the lysimeters.

The approach consists of 17 lysimeters each containing three tons of raw
compacted waste. These lysimeters are located at the EPA Center Hill Facility
in Cincinnati, Ohio. Fifteen of these cells are outside of the building while
two are inside the building at room temperature. There are two stages to the pro-
gram. The first stage is preparation of the cells, characterization of the waste
and placement of the waste into the cells along with the instrumentation. The
second phase is monitoring the cells for gas composition and volume, leachate
composition and volume, temperature, pressure, settlement, water applications
and the application of polio viruses into one of the cells. Water application
rate is according to average U.S. rainfall pattern. The study is to last for
approximately three years.

The current plans are to load the lysimeters approximately four months after
the start of the effort, and then to commence full-scale monitoring of the cells
for the remainder of the effort. The data will be reduced on a continuing basis
in order to obtain trend information.

PROJECT DESCRIPTION:

The principal objective of this project is to demonstrate upgrading of an
existing air aerated activated sludge plant with a simplified single-stage
oxygen contact system, using existing aeration tanks, blowers, and diffusers
to greatly reduce the cost of dissolution equipment.

A 2 mgd aeration bay at the Las Virgenes Municipal Water District Tapia
Water Reclamation Facility has been converted to a single-stage oxygen system
using an inflated oxygen tent tank cover to contain the oxygen-rich atmosphere
over the aerator. A conventional centrifugal air blower, corrosion proofed on
the suction side and modified to be compatible with oxygen gas, is used to re-
circulate gas from within the tent cover through conventional coarse bubble
spiral roll air diffusers. Virgin oxygen is introduced to the system through
a fine bubble sparger. This simplified oxygen dissolution concept was designed
by the Cosmodyne Division of Cordon International.

The system is currently being evaluated on a one-year demonstration run.
One conservatively designed phase (nominal aeration time based on raw waste-
water flow = 9.5 hours) has been completed to date to determine if effluent
acceptable for agricultural recycle could be produced. Effluent quality for
the phase averaged BOD, = 2 mg/1, COD = 35 mg/1, suspended solids = 9 mg/1
and was completely nitrified. At the high sludge age (>70 days) induced by
this type of operation, total biological sludge production was virtually nil.
However, the reduced sludge wasting pattern permitted a buildup of grease
and other poor settling debris, thereby deteriorating sludge settling char-
acteristics (SVI = 200 ml/gram +). Subsequent phases of the experimental
program will examine system performance and sludge characteristics at 4 and 2
hours of nominal aeration time (based on raw wastewater flow).

PROJECT DESCRIPTION:

The objective of this project is to develop a method utilizing specific site
characteristics to predict the migration through soil of gases produced from
sanitary landfilling of solid waste. This method will help to meet the need
to rationally evaluate the potential environmental hazards associated with
migrating gases.

The approach is to develop, from information available primarily in the field
ot gas flow through porous media, a comprehensive, three-dimensional model capable
of predicting gas flow through nonisotropic, heterogenecus soils under transient
and steady-state conditions. The predictive method is intended for routine use
by design and regulatory engineers utilizing simulations generated from the
comprehensive model. Thus, several typical sanitary landfills will each be simu-
lated to allow easy solution by use of charts, nomographs, and/or simple equations
sensitive to specific site characteristics.

Field verification of the model to be developed and comprehensive evaluation of
gas production will need to be performed in addition to this project to allow
rational evaluation of potential hazards associated with migrating gas from a
specific landfill, either planned, in operation, or completed.

The objective of this project is to design, construct, and evaluate
a permanent polymer injection station on the Bachman Creek Sewer in Dallas,
Texas. This project will further demonstrate and evaluate a technique
developed earlier for FWPCA by contract which utilizes injection of polymers
into a sewer for the purpose of increasing the carrying capacity of the pipe.
During periods of wet weather the Bachman Creek sewer receives excess
quantities of ground or stormwater due to infiltration. The flow then
exceeds its carrying capacity and untreated wastes overflow in at least ten
locations, causing pollution of Bachman Creek. This project will seek to
eliminate or greatly reduce the number and volume of untreated overflows
by increasing the flow capacity of the Bachman Creek Sewer through the addition
of polymers. Design criteria, operating techniques, optimum polymer concentration
and other pertinent data critical to the intended use will be evaluated.

PROJECT DESCRIPTION:

This study involves an analysis of the cost of damages that result from
the use of salt (sodium chloride and calcium chloride) on highways to melt
snow and ice. A large literature search and several surveys were carried
out in order to determine the types and extent of damages that have occurred.

An in-depth analysis was performed on all of the data obtained. The
major cost sectors examined were: water supplies and health, vegetation,
highway structures, vehicles, and utilities. For each of the sectors, a
cost estimate was developed. The total annual national cost of salt
related damage approaches $3 billion dollars or about 15 times the annual
national cost for salt purchase and application. While the largest costs
result from damage to vehicles, the most serious damage seems to be the
pollution of water supplies and the degradation of health which may result.
It is particularly difficult to assign costs in this latter area and
therefore the estimate may substantially understate the actual indirect
costs to society.

These findings indicate that the level of salt use should be reduced.
The amount of the reduction should be determined on the basis of local
conditions. A final report will be available shortly after the above
completion date.

PROJECT DESCRIPTION:

Proper disposal of sewage effluent from rural and isolated homes and businesses
is one of the most difficult problems facing health authorities. This is
particularly true in areas where soil conditions are unsuitable for application
of leaching fields following septic tanks. These conditions are in many areas
having high ground water tables and in other areas where bedrock is close to
the ground surface. Under these conditions, an evaporation type system concept
can be used to dispose of the wastewater without adverse effects on the land
or ground water.

The objectives of this study are to determine rational design criteria,
estimated costs and potential applicability of evapotranspiration (ET) and
mechanical evaporation (E) systems for disposal of wastewater from individual
homes. Specific objectives are the quantification of major design parameters,
such as soil type, saturated liquid depth and vegetative cover for ET systems
and physical and mechanical factors for E systems, by thermodynamic studies,
pilot studies, and in the case of ET systems, monitoring of existing full-scale
systems. By use of meterologic and hydrologic data from approximately five
locations in the United States, estimates of cost and applicability of these
types of systems will be made for these locations, representing a wide spectrum
of climatic conditions.

PROJECT DESCRIPTION:

In both cases--septage treatment and disposal and vacuum sewage collection--a
standard of engineering practice has not yet emerged. In view of the need to
provide smaller communities with low cost solutions to problems associated with
wastewater control, there is a need to provide these communities with more
definite information on methodologies for handling septage and evaluating the
potential of vacuum sewage systems. Likewise, regulatory agencies and consult-
ing engineers need to define bases for evaluating and designing cost-effective
alternatives in each area.

Therefore, this proposal addresses both of these problem areas in order to
provide information to Federal, State and local regulatory agencies, and consulting
engineers so that these problems can be dealt with in a more orderly and comprehen-
sive manner. It is expected that the results of this study program will be used in
the following way:

1) Smaller communities will be provided with a basis for evaluating alterna~-
tives.

2) Consulting engineers will be provided with data and information whereby
cost-effective designs can be formulated.

3) Regulatory agencies will be provided with information upon which
regulations, policies and programs may be based.

PROJECT DESCRIPTION:

The utilization of municipal solid waste as a supplementary fuel for boilers
in use at industrial establishments was investigated. A survey of the industrial
sites, different boiler designs determined their potential for burning solid
refuse as part of the fuel. Included in this survey was an assessment of modifi-
cations necessary to the boilers, operational problems expected from using solid
waste as part of the fuel, the form the solid waste must be in, and a projection
as to the expected effectiveness of each system. Several industrial boilers were
selected for field testing.

A final report is in preparation.

PROJECT DESCRIPTION:

The aims of this project are to determine, through laboratory and pilot
studies, the necessary information for rational physical design of filters
for use in wastewater treatment. Primary emphasis is placed on determining
the relationships between media characteristics and the physical requirements
of reactor design. The project theme is based on the factors which influence
the ability to thoroughly cleanse the media during the backwash cycle. All
individual studies are designed toward gaining maximum understanding of these
factors.

Laboratory studies on the expansion and intermixing of various types and
sizes of granular filtration media are well underway and will be completed
during this budget period. The causes and effects of intermixing of media
will be continued in the laboratory and will be instituted in the pilot plant.
The relative effects of different auxiliary washing techniques will also be
studied in the pilot plant in parallel to assess the utility of these tech-
niques. Also, the necessary quality of backwash water and/or physical equip-
ment involved in the backwashing system will be assessed along with variations
in washing techniques.

PROJECT DESCRIPTION:

The objective of this project is to develop a technically feasible and
economically attractive open-tank oxygen aeration activated sludge system.

An ultra-fine (<0.2 mm) bubble diffuser, developed by Martin Marietta
Corp., will be evaluated for feasibility of dissolving oxygen gas and obtaining
a high overall oxygen utilization factor in an open-tank activated sludge
aerator. (Commercially available oxygen aeration systemsto date have all
utilized covered-tank aerators.) The diffuser works on the shear principle with
mixer liquor continuously recycled through the diffuser at right angles to
injected oxygen gas. To be economically realistic, 90% or greater of the oxygen
bubbles must dissolve before rising to the aerator liquid surface. This concept
will be evaluated in a 30 gpm pilot plant located on the grounds of a suburban
Denver wastewater treatment plant.

At the date of this writing, the 30 gpm pilot plant is in the process of
being fabricated. A one-year experimental program will commence in spring
1973 after installation and "shakedown".

PROJECT DESCRIPTION:

Objective: To demonstrate nutrient removal for reclamation of wastewater.
Approach: A 0.26 MGD (pilot scale) nutrient removal wastewater treatment facility
was constructed and operated for 12 months. The major steps involved were:

(a) phosphate incorporation into biological sludge and nitrification in an aeration
basin: (b) sludge-liquid separation by either vibrating screens and/or dissolved
air flotation; (c) the liquid phase is treated for nitrogen removal (denitrification)
in an upflow sand filter with methanol addition as organic food source; (d) the
concentrated sludge (2% to 3%) from the vibration screens and/or dissolved air
flotation is treated with acid (sulfuric) to reduce the pH to around 5. At this

pH the phosphate in the sludge is solubilized; (3) the phosphate laden liquid
phase is separated from the solid (sludge) phase by co-current solid bowl centri-
fugation. The phosphate free sludge is recycled to the aeration basin. Thus
mechanical separation is used to separate the liquid and concentrate the sludges

as quickly as feasible to avoid biological sludge deterioration.

Progress: (a} Dissolved air flotation is a very effective process for separating
mixed liquor. The flotate (sludge solid phase) can be concentrated to 3% solids;
(b) Up flow sand filtration provides an excellent media, with methanol addition,
for denitrification. Care must be taken to avoid solids breakthrough by nitrogen
gas bubbles; (c) The combination of nitrification in the aeration basin, dissolved
air flotation for solids-liquid separation, and adding methanol as organic food
source to the liquid influent feed to the upflow sand filter, results in up to

95% nitrogen removal; (d) Vibrating screens are not an effective separating
device for mixed liquors; (e) Phosphate removal could not be demonstrated

because of the ineffectiveness of the co-current solid bowl centrifuge to separate
the phosphate laden liquid from the sludge. Solids losses in the centrate were
excessive; (f) A final report is being prepared.

confirm on a sound statistical basis, and further improve the favorable results
obtained on the pilot capillary sludge dewatering device developed under EPA
Contract No. 68-01-0094 (17070 HCZ). Specific objectives are to determine:
(1) the effect of scale-up on system engineering parameter performance and
mechanical requirements, (2) system reliability from a process and mechanical
standpoint, and (3) an economic basis for system evaluation. The period of
the study will be twenty four months. It is expected that the capillary
device will attain higher filter yields and lower cake moistures and that the
sewage will require less chemical conditioning than has heretofore been possible
with existing dewatering equipment. Dewatering effectiveness will be measured
by (1) sludge cake output or yield, (2) sludge cake characteristics, (3)
solids removal efficiency, (4) liquid process stream quality, (5) conditioning
chemical usage, and (6) cost of dewatering.

other than enteric forms. The relationship of these pathogens to the
customary microbiological indication of sanitary water quality will be
established. The results should suggest the type and degree of stormwater
treatment necessary for the protection of health. Routine sampling will
be made sewage at the wastewater treatment plant for reference and waters
flowing in the urban streams to obtain background information. Sampling
Stations for stormwater will be set up at six sites ranging from relatively
clean residential drainage area to the inner city characterized by

industries and heavy residential areas. One of the sampling stations will
be a combined sewer system.

The study will, of necessity, include evaluation of sampling equipment

and methods and cultured materials. The project is expected to be completed
in two years.

PROJECT DESCRIPTION:

The objectives of this research are two: (1) to undertake an analysis
of the feasibility, benefits and costs of using building permit data to
estimate and project the future demand by user class for water and subsequent
investment in supply and distribution networks, and (2) to develop estimates
of operating and capital costs, and cost and supply relationships as a function
of space and topography, as related to cost/rate differentials among users of
the samé class and different classes (residential commercial, industrial).

This aspect of the research is concerned with estimating the degree of internal
cross-subsidies in the system.

The approach utilizes data from building permit applications and water
supply records for the Cincinnati Water Work supply area. The analysis will

utilize statistical analysis to estimate the relationships and test the
appropriate hypotheses.

PROJECT DESCRIPTION:

The project objective is to develop a high efficiency biological treatment
process and other related process units that is, especially useful for smaller
communities, compatible with modern requirements and technology.

A novel 120,000 gpd pilot plant has been constructed on the grounds of the
New York State Vocational Institute in West Coxsackie, New York, to treat the
sewage of the resident inmate population. The treatment facilities consist of
an aerated equalization tank, a two-stage split-culture activated sludge regime,
intermediate upflow activated sludge clarifiers, multi-compartment horizontal
flow (with inclined trays) final clarifiers, a multi-compartmented tank for
batch aerobic digestion of waste activated sludge, and Purifax equipment for
high pressure chlorination treatment of primary sludge.

A two-year experimental development program has recently begun in which the
above facilities will be evaluated in various sequences to optimize treatment
of small (but widely varying) flows for maximum removal of organic carbon
materials, suspended solids, phosphorus, and nitrogen. The results of this
project will have greatest application to small communities with typical broad-
swing diurnal flow patterns.

PROJECT DESCRIPTION:

Two dual media (coal over sgnd) automated pressure filters each with
a maximum capacity of 10 gpm/ft” will be utilized in parallel to filter
secondary effluent from the main (10 MGD) Pomona secondary treatment plant.
The following will be evaluated during the study:

(a) Air plus water backwash vs. surface wash plus water backwash.

(b) Injection of alum just ahead of the filter vs. direct filtration
of secondary effluent.

(c) Effect of addition of anionic polymer with alum directly ahead of
the filter.

(d) Comparison of alum coagulation and sedimentation vs. direct feed
of alum prior to filtration.

The performance will be judged on the basis of effluent suspended
solids and rate of pressure drop build up. Although most of the studies
will utilize non-nitrified secondary effluent, some runs will be made
with nitrified effluent from the nitrification stage of the units used
in task 21-ASO 030.

Program No. 11024 DGZ, (Contract 14-12-486) in the design, construction and
operation of a full-size combined sewer fluidic regulator installed in two
typical locations in the Philadelphia sewer system.

The specific objectives of the project are the following:
1. Design, construction and operation of a fluidic regulator for a
flow range below 2 CFS with a minimum of reconstruction. The unit
will be capable of demonstrating fluidic action on demand by use of
city water to simulate storm flow and a transparent top for observation.
2. Design, construction, and operation of a fluidic regulator for a
4 CFS peak dry weather flow. This will demonstrate the use of a
fluidic device at higher flows on combined sewerage. The automatic
control of the overflow will be done by sensing the interceptor level.
No overflow will occur until the interceptor reaches a pre-determined
limit.
3, Evaluate the operation of above fluidic devices over a years' period,
and relate their performance, both advantages and disadvantages to
conventional regulator throughout the Philadelphia sewer system.
4, Assembly of all data from the evaluation and testing program
including rainfall data, overflow vs. sensor height, so that the application
of fluidics to sewer design can be demonstrated on a full-scale basis.

The project purpose is to provide capital and operating cost data for
evaluating specific waste treatment alternatives; to determine electrical and
other energy requirements for conventional and selected advanced waste treat—
ment alternatives; and to determine the marketability of sewage sludge compost.
The specific waste treatment alternatives for which capital and operating cost
data are to be provided include filtration, coagulation/sedimentation, sludge
transport, stormwater treatment, thermophillic aerobic digestion, and cost/
effects from heat treatment of sludge. The approach will be to assimilate
actual material and labor requirements from selected existing facilities, to
determine capital costs, synthesize plant facilities for sizes not determined
by actual construction records and to survey plants to determine manpower
utility and miscellaneous requirements associated with operating the facilities.

Additional studies to be performed include energy use and conservation in

municipal treatment plant design and operation, and an engineering evaluation
and cost analyses of suspended and attached growth biological processes.

PROJECT DESCRIPTION:

The primary objective of the workshop will be to define and establish
priorities for research needed to automate wastewater treatment plants.
However, since the input to a plant comes from a collection system and
the output is normally discharged to a receiving body of water, attention
will also be devoted to research needs for these systems with special
reference to their interaction with treatment plants. Also addressed
will be the effect of automation on design and operation of wastewater
recycle systems.

The workshop will be three days in length with the first day being
devoted to the presentation and discussion of state-of-the-art papers.
Six separate workshop sessions will then be devoted to preparation of
brief documents stating the problems and specifying needed research for
each session topic. These documents will then be presented to the reassembled
group for detailed discussion. The final day will be devoted to a tour of
a new 120 MGD activated sludge plant which is highly automated and features
on-line computer control. This tour will afford participants the opportunity
to observe first hand the state-of-the-art of automation and problems
which need to be solved.

The proceedings of the workshop, including the discussions will be
published under the title "Research Needs in the Automation of Wastewater

Objectives of the study are: (a) Establish the effects of application of
sludge on forest growth rate; (b) Establish efficient and effective methods of
sludge application to forests; (c) Establish the rate of sludge application
which has maximum benefits to forest growth with minimum impact on soil water
quality and be nonpolluting to surface or ground waters; (d) Establish the
short-term impacts of sludge application on the forest, including effects on
microbiological organisms and higher plant species, physical and chemical
properties of the forest and soil, and the chemistry of soil water.

The second year will continue with evaluation of the above objectives, and
place particular emphasis on retention, movement and soil mass balance of
certain elements contained in the sludge. Varying rates of sludge application
on the mass balance of applied chemicals and forest growth will also be empha~
sized.

Retention movement and mass balance of chemicals contained in sludge including
total organic analyses will be evaluated by resampling the forest soil by depths to
establish the changes in elemental constituents, after application from the pre-
treatment condition.

Identification of the mechanisms of retention and movement of certain chemical
elements is proposed through use of radioisotopes. The isotopes will be placed in
confined soil columns and sampled at six-month intervals identifying the penetration
of tagged isotopes to the type and size of soil particles.

Microbiological composition of the forest biomass will continue to be moni~
tored for detection of rates of solubility changes, a specific concern being the
susceptibility of microbial organisms to heavy metals at levels which may be toxic.

Isolation attempts are being made utilizing methods which give maximum
control of oxygen tension. 0/R potential is being maintained below-300 mv.
Intermediates and rates are being investigated using isotope dilution tech-
niques.

The hydrogen utilizing methanogenic microflora has been isolated and its
ecological function has been demonstrated. Hydrogen has been shown to inhibit
short chain fatty acid metabolisms. The hydrogen utilizing microflora maintains
the hydrogen concentration below a toxic level.

Current studies involve efforts to develop a methane fermentation which is
insensitive to environmental changes. This is being approached by selection of
insensitive mixed populations of organisms capable of dissimilating organic

PROJECT DESCRIPTION:

The objectives of this project are two-fold: (1) to define the lagoon
equivalency to disinfection without addition of disinfecting agents; (2)
to determine whether the lagoon effluent can be chlorinated to destroy total
and fecal coliforms without adversely affecting the organic quality of the
effluent stream. Theoretically, application of large doses of an oxidizing
agent such as chlorine to a lagoon effluent containing high quantities of
algae may result in an unfavorable increase in the effluent soluble BOD due
to algal lysis. Thus, one process (i.e. disinfection) achieving compliance
with one standard (i.e. coliform reduction) might induce noncompliance with
another standard (i.e. effluent BOD reduction).

Flexibility of the Logan (Utah) lagoon allows placement of chlorinators
and chlorine contactors at any desired location. Construction of inter-
mittent slow-sand filters following the final cell of the lagoon has been
completed on EPA Contract 68-03-0281. One 50,000 gpd flow stream will be
diverted from a secondary cell of the lagoon, passed through the sand filter,
and then chlorinated, for comparison with three identical but unfiltered
50,000 gpd flows receiving different chlorine dosages. The usual chemical
analyses will supplement all bacteriological tests. Since the BOD test is
unreliable in chlorinated effluents, soluble COD tests will be performed to
measure the extent of algal lysis following chlorination.

PROJECT DESCRIPTION:

This project will evaluate the extent and magnitude of hazardous waste
migration and resultant groundwater pollution from 3 known land disposal
sites in Illinois. During the study special emphasis will be given to sites
underlain by low-permeability clay and silt soils which have received large
volumes of hazardous materials such as arsenic, cadmium, chromium, cyanide,
lead, mercury, and pesticides. Methodology and technology from the fields of
groundwater hydrology, geology, agronomy, chemistry, and geophysics will be
employed in the work which will be supervised on a full-time basis by the
principal investigator, a groundwater hydrologist assisted on a part-time
basis by an associate geologist and a consultant agronomist. Chemical
analyses of soil cores and groundwater samples will be the primary investi-
gative tools used to quantitatively evaluate chemical migration from each of
the 3 disposal sites. Data collection will be obtained primarily by contract-
ual work from commercial soils and chemistry laboratories.

The findings of this study should provide an invaluable tool to employ in
predicting possible ultimate adverse effects of land disposal of hazardous
materials in time to permit perfection or development of technology required
to insure future minimal danger to public health from this particular waste
disposal practice. Also, the findings should be immediately applicable for
use in evaluating the extent and magnitude of hazardous chemical migration
from disposal sites situated in similar geohydrologic environments throughout
Illinois and much of the other 15 glaciated, humid-region States in the country.

Plant performance will be evaluated with respect to parameters of potable water
quality, and special animal virus studies will be conducted to determine
the effectiveness of the pilot processes (nitrification, high pH lime clarifi-
cation, filtration, and carbon adsorption) in the removal of virus and other
pollutants adversely affecting the reuse potential of the effluent for potable
and non-potable purposes. In addition to the efforts conducted by the pilot
plant staff, special samples of effluent will be concentrated and the organics
captured by an EPA contractor for subsequent EPA animal toxicity studies.

The AWT pilot plant will also be used to conduct a feasibility study of
ultraviolet (UV) light disinfection of 2 types of activated sludge effluents.
(1) a nitrified effluent; and, (2) a standard high rate effluent, Both
effluents will be tested with and without tertiary settling, chemical addition,

lagoon effluent.

The effluents from each of these plants contain unoxidized nitrogen compounds
in the form of organic and ammonia nitrogen. Two rotating biological contactor
(RBC) pilot plants will be designed, fabricated, and installed, one each, at the
effluent end of the above two full-scale treatment plants. The principal objec-
tive of this research project is to operate and monitor these pilot units to
determine whether RBC's can induce nitrification of and some incremental overall
quality improvement in the effluents of either or both of these plants. If the
results are positive, the secondary objectives will be to optimize performance
and generate design factors for extrapolation to construction of larger-scale
second-stage RBC nitrification systems.

PROJECT DESCRIPTION:

The Upper Thompson Sanitation District (U.T.S.D.) was formed to provide waste-
water treatment services to the area surrounding Estes Park, Colorado. This area
is adjacent to the Rocky Mountain National Park, a major tourist attraction in
Colorado. Because of the highly visible area that the U.T.S.D. will serve, numer-
ous processes had to be included in the plant design to achieve the desired treat-
ment objectives.

As a result, a unique combination of conventional and advanced waste treatment
processes were developed. Major components of the treatment scheme are: flow
equalization, activated sludge treatment, biological nitrification, multimedia
filtration, and ozonation for disinfection. Flexibility of phosphorus removal
has been provided and with minor additions attached growth denitrification on
the multimedia filters can be incorporated into the system.

This combination of processes represents a culmination of process development
work that has previously been carried out at the field scale by various investi-
gators. The proposed research project will verify on a full scale basis many
processes that have been shown to be feasible alternatives to accomplish advanced
wastewater treatment of municipal wastewater.

An essential research feature will be the full-scale comparative study of two
different types of attached growth nitrification media.

The desired effluent quality will manage not only to meet Colorado State
requirements but also tuned to 1977 guidelines of best practicable treatment.

The research on ozone as a suitable full-scale alternate to chlorine as a
municipally used disinfectant has national significance.

PROJECT DESCRIPTION:

The principal objective of this project will be to demonstrate that
real-time automatic operational control technology can be implemented for
combined sewer systems in metropolitan areas. To accomplish this objective,

the project will be divided into two major phases: (a) a development phase, and
(b) an application phase.

The development work will include the following three items:

(a) Development of the control software for the demonstration system,
(b) Development of a short-term (minutes and hours) rainfall prediction
capability, and

(c) Development of a relatively simple rainfall-runoff model that can
be used for real-time simulation.

The ultimate product of the development phase’ will be the control
system software required for the prototype demonstration system. However,
a major objective of this phase will be to approach the developmental work
in a generalized manner to the maximum extent possible so that the results

of this work can be used by other cities contemplating real-time automatic
control of their storm drainage systems.

Tite objectives of the application phase of the study are:

(a) To demonstrate how the generalized simulation and control models
developed in the first phase of the work would be adapted to a
specific system, and

(b) To show that the automatic real-time control system will work
as it was intended.

PROJECT DESCRIPTION:

The objectives of the first year of a three year research project to
collect, for the first time, detailed information defining the physical
characteristics of an urban drainage area tributary to a combined sewer drainage
system and detailed data relating to the quantity and quality of various sources
of pollution within the combined sewer drainage area has been successfully com-
pleted. Generally in the past, data have been collected only at the actual
overflow location from a drainage area. The collection and evaluation of
data from within the tributary drainage area will provide valuable insights

regarding methods for controlling the strength and volume of combined sewer
overflows.

The second year of the project concentrated on the verification and improve-
ment of a basic mathematical model using the data collected as well as other
available data.

A comprehensive stormwater management mathematical model has been developed
for predicting the quantity and quality of combined sewer overflows. The detailed
data collected were utilized for verification of this model. Communities needing
a working tool for development of combined sewer overflow abatement programs will
be able to utilize this model effectively. A final report is being prepared.

of granular media filters for tertiary treatment of municipal wastewaters in the
continental U.S., 2) to collect and evaluate the operating data which are avail~
able for the tertiary filters in the States of Illinois, Indiana, Michigan and
Wisconsin, and 3) to carry out a detailed evaluation of the performance of a
number of tertiary filters. Tertiary filters are intended to achieve higher
levels of removal of BOD and suspended solids from municipal wastewaters than
can be achieved by secondary treatment alone. The filter performance will
largely depend on filter design and operation. Performance may also vary
depending on whether an activated sludge process or a trickling filter is
used for secondary treatment. The approach for this project will be to obtain
operating data from tertiary filter installations in Illinois and select two
filters for a preliminary sampling period. Samples will be obtained of the
secondary and tertiary effluents. These will be analyzed for BOD, suspended
solids, and several other water quality parameters. Statistical distributions
of loading and performance parameters and effluent variables will be obtained.
The dependence and independence of variables and parameters will be tested.
Hypothetical functional relationships between performance parameters and inde-
pendent variables will be determined. Hypotheses about operation and perfor-
mance will be ascertained. The composite of this information will serve as a
framework to analyze data obtained in a twelve-month intensive sampling period
of a number of tertiary filters.

the effectiveness of various landfill operations in controlling HCB loss in Lhe
vapor phase.

Hexachlorobenzene is a stable, persistent, water insoluble chemical with a
reported vapor pressure intermediate to that of the organochlorine insecticides
dieldrin and lindane. Hexachlorobenzene in addition to being a registered
fungicide is present as a byproduct in the commercial production of certain
chlorinated compounds. Landfill is one possible mode of disposal of the
industrial wastes from these processes and it is essential to know the potential
for movement and loss via the vapor phase as a function of the method of opera-
tion of potential landfill sites. Models have been developed and tested in the
laboratory for soil and environmental facts affecting the vapor phase movement
and volatilization of lindane-treated soils. These models are being applied to
the movement and volatilization of HCB which is a non to weakly polar chemical
expected to behave similar to lindane.

PROJECT DESCRIPTION:

The objectives of Phase I are to: (1) characterize the residual sludges arising
from the treatment (physical, physical-chemical, and bio-chemical) of combined
sewer overflows; and (2) develop promising alternative sludge handling/disposal
treatment process flow sheets and an engineering evaluation of the alternative
flow sheets developed.

The objectives of Phase II are to: (1) evaluate on pilot-scale the effective-
ness of thickening-certrifugation treatment system for CSO residual sludges and on
a bench-scale the effectiveness of anaerobic digestion of appropriate sludges;

(2) develop basic design criteria and operating characteristics of the thickening-
centrifucation dewatering system in a form that can be translated into actual
practice with minimum delay; (3) develop capital and operating costs for the
demonstrated treatment system; (4) evaluate, on a nationwide basis, the extent

of the wet-weather flow sludge problem with respect to quantities generated,
characteristics, and facility and cost requirements for handling and disposal;

(5) evaluate the "shock-load" effect of CSO treatment residuals on dry-weather
treatment plant operation and performance; (6) evaluate alternative methods for
ultimate disposal of raw CSO sludges and treated CSO sludges.

PROJECT DESCRIPTION:

The purpose of the research is to define the applicability and limitations
of the dehydrogenase assay for measurement of the active biomass associated
with biological treatment of domestic and industrial wastewaters. The specific
objectives are: (a) to study the effects of varying organic content and nutri~
tional deficiencies on the dehydrogenase activities of biological sludges, (b)
to study the relationship between the active biomass concentrations and dehydro-
genase activities of biological sludges undergoing endogenous metabolism, and
(c) to develop a laboratory procedure for correlating dehydrogenase activities
with the active biomass concentrations of biological sludges obtained from proto-
type and industrial treatment processes.

The studies have been conducted with pure cultures of bacteria and mixed
cultures in batch and continuous flow systems using a variety of defined food
materials or actual wastes. The range of dehydrogenase enzyme activity under
the varying conditions has been established as well as a definite correlation
between dehydrogenase activity and ATP content of the cells.

PROJECT DESCRIPTION:

A study of published and unpublished literature to develop an in-depth
report on the quantity and quality characteristics and the pollutional
significance of stormwater, non-sewered runoff, and CSO on a nation-wide
scale will be conducted. The study area shall be broken down into local,
state, regional and national segments to obtain a picture of maximum complete-
ness in light of available information. An important outcome of the project
will be the contractor's recommendations for strengthening the data bank in
specific areas where information is sparse.

It is anticipated that the contractor will have computer capabilities
and will be familiar with math modeling to the extent that handling storm-
generated pollution from point and non-point sources will not present a
significant problem. To the maximum possible extent, the methods of data
presentation and reduction will be fully compatible-with the EPA Stormwater
Management Model (SWMM) or its modification. Potential use of the runoff/
sewer section of the SWMM can be used to fill gaps and make more complete
evaluations at specific geographic locations.

PROJECT DESCRIPTION:

The sole purpose of disinfecting potable water supplies is the destruction
of pathogenic organisms and, thus, the elimination and prevention of waterborne
disease such as those caused by viruses. The overall objective of the study is
to determine the range of sensitivity of various enteric viruses (e.g. picorna~
viruses) to chlorine. Using carefully controlled laboratory experiments, the
sensitivity response will be characterized with respect to such variables as
type of virus, level and nature of chlorine, and quality of the suspending medium
(water). Both chlorine demand free water and natural waters will be used.

The sensitivity of viruses continuously maintained under laboratory conditions
will be compared to new isolates obtained from fecal matter. The mechanism
of inactivation, with respect to whether the viral genome or protein coat is
affected, and whether the inactivation is reversible, will also be examined.

PROJECT DESCRIPTION:

The Storm Water Management Model (SWMM) has proven itself to be a
useful computer simulation tool for studies of pollution caused by storm
and combined sewer overflows. However, documentation of model usage lacks
a clear, concise, logical sequence for users to follow. An extensive effort
will be made to revise the present User's Manual to correct for this defect
and others and to completely update the model. In addition, refinements
will be added to flow routing procedures to account better for backwater,
interconnections and surcharging. Treatment and solids handling alternatives
other than those presently considered in the SWMM will be examined for
application to pollution control. Finally, planning guidelines will be
prepared for use by those charged with obtaining least cost, yet environmentally
sound solutions to urban drainage and pollution problems. These guidelines
will include the results of all available research.
