NEW LOGIC RESEARCH

Overview

A unique membrane filtration system has been installed at

several major waste oil hauling operations and

manufacturing plants that handle or produce oily wastewater.

The system manufactured by New Logic, of Emeryville

California near San Francisco, is also being used to process

used crankcase waste oil and produce filtrate that can be

sold as a higher value bunker oil. The V✧SEP, (Vibratory

Shear Enhanced Process), system uses a membrane module

with special construction for service with high temperature

solvents and waste oils and is able to recover up to 90% of

the oily wastewater as clean water. The use of high

temperature polymeric membranes has many significant

advantages over the conventional methods of oily water

treatment. There are dozens of methods used for oil water

separation. Each technique has advantages. No one technique

is suitable for all situations. V✧SEP has very good overall

usefulness. Membranes have the advantage of being simple

efficient separating devices to hold back oil, grease, metals,

BOD, and COD. They can provide clear permeate which

can be sewered or re-used.

Membranes

Membrane separation technology has been around for many

years. Initially, the use of membranes was isolated to a

laboratory scale. However, improvements over the past

twenty years have made it possible to use membranes on an

industrial level. A membrane is simply a synthetic barrier,

which prevents the transport of certain components based

on various characteristics. Membranes are very diverse in

their nature with the one unifying theme to separate.

Membranes can be liquid or solid, homogeneous or

heterogeneous and can range in thickness. They can be

manufactured to be electrically neutral, positive, negative

or bipolar. These different characteristics enable membranes

to perform many different separations from reverse osmosis

to micro-filtration. There are four main categories of

membrane filtration. These are determined by the Pore size

or Molecular Weight Cut off

Filtration Type Particle Size Molecular Weight

Reverse Osmosis ≤ 0.001 μm ≤ 100 Dalton

Nanofiltration 0.001-0.01 μm 100 - 1000 Dalton

Ultrafiltration 0.01-0.1 μm 1000-500,000 Dalton

Microfiltration ≥ 0.1 μm ≥ 500,000 Dalton

Using Vibrating Membranes to

Treat Oily Wastewater from a

Waste Hauling Facility

Reverse Osmosis Membranes

The first category of membranes is for Reverse Osmosis.

These are the tightest membranes for separating materials.

They are generally rated on the % of salts that they can

remove from a feed stream. However, they can also be

specified by Molecular Weight cutoff. Usually, the rejection

of NaCl will be greater than 95% in order to be classed as

an RO membrane. The molecular weight cutoff is shown in

the table to the left. An example of their use would be for

filtering seawater in order to remove the salt. They are also

used to remove color, fragrance and flavor from water

streams. Reverse Osmosis membranes don’t have structural

pores. Filtration occurs as ionic species are able to diffuse

their way through the membrane itself.

manufacturing facility for oily water filtration.
Nanofiltration Membranes

A great deal of recent research has led to the improvement

of membranes in the range of Nanofiltration. As the name

suggests, these membranes are used to separate materials

on the order of nanometers. These membranes are not

usually rated based on their pore size because the pores are

very small and difficult to measure accurately. Instead they

are rated based on the approximate molecular weight of the

components that they reject or the % of salts that they can

remove from a stream. These membranes are used

predominately for wastewater treatment but they are also

used to concentrate material that has a wide range of particle

sizes.

Ultrafiltration Membranes

Conventional Ultrafiltration membranes are composed of

some type of polymer material with pores ranging from a

little less than 0.01 μm to 0.1 μm. These membranes are

used for many different separations including oily

wastewater treatment, protein concentration, colloidal silica

concentration and for the treatment of various wastewaters

in the Pulp & Paper industry.

Microfiltration Membranes

These membranes tend to be porous, with pores greater than

0.1μm. These types of membranes are used to separate larger

particulate matter from a liquid phase. Some examples

would be coarse minerals or paint particles, which need to

be concentrated from an aqueous solution.

Oily Wastewater

Oil/Water separation covers a broad spectrum of industrial

process operations. There are many techniques employed

depending on the situation. This summary will address those

separations, which are suited to the V✧SEPs membrane

technology. The oily wastewater application can be broken

down into categories determined by the type of user and the

oil/ water separation desired.

Types of V✧SEP Oily Wastewater customers:

Barge/Bilge Water from marine operations

Manufacturing where oily water is a waste product

Waste haulers & recyclers

There is a saying: “Oil and Water don’t mix”. This is true,

but they can exist as an emulsion. Oil is not soluble in water

but it can exist evenly dispersed as globules in water. The

concentration of these globules is a function of mixing or

stirring. If allowed to stand the emulsion will separate

because oil is lighter than water, although, some amount of

oil globules will remain in the water. Another interesting

fact is that this emulsion can exist two ways. If the

concentration of Oil is less than 50%, the water will be the

suspension fluid and the oil will be the globule. A phase

transition occurs if the oil content is more than 50%. When

this happens, the oil is the suspension fluid and the water

forms globules. For this reason, hydrophilic membrane

separations will be possible only when the oil content is

less than 50%.

Commercial Uses

Sometimes mixing of oil and water is intentional and some

times it is an unavoidable necessity. The following are

instances of oil water mixtures:

Produced Water: Water is injected into drilling shafts to

displace oil. Barge/Bilge Water: Wash down cleaning

operations contaminated by oil. Machining Coolant: Oil

mixed with water acts as a lubricant to reduce tool wear.

Washwater with Degreaser: Fluid used for cleaning oily or

greasy parts. Lubricant Manufacturing Wastewater

Relative Operating Cost comparisons of various

technologies for treating oily wastewater
Comparisons of Oil Water Separation Technologies

Centrifuge: Uses large horsepower motors and because of

the number of moving parts is subject to high maintenance.

While centrifuges are effective at removing suspended

solids, they do not account for dissolved solids and heavy

metal species in solution. The effluent from a centrifuge

would need further treatment prior to disposal.

Rotary Drum Vacuum Filter: Quite effective at rejecting large

solids. sometimes filtrate must be sent back around to get

all of the smaller particles. Usually employs coarse filtration.

Vacuum filters require large floor areas and have high capital

costs

Dissolved Air Flotation (DAF): Large tanks where air is

bubbled into the bottom and with the use of flocculants,

solids are floated to the top and skimmed off. A very large

tank is required due to the residence time required. Also

chemical addition is a daily if not hourly process and is a

significant operating cost.

Slope Plate Clarifiers: Cheap and easy to use. The process

relies on gravity to drop out heavy solids. Here again

colloidal materials with small mass and dissolved

constituents do not settle. Sometimes it is used in conjunction

with flocculation chemicals. These chemicals have limited

effect in dropping out heavy metals, BOD, and COD.

Biological Treatment: This process relies on biological

activity to digest the solids in the wastewater. The problem

is that the system is extremely temperature and pH sensitive.

Also loading must be done at a set rate. The operation of

this kind of system usually requires a very skilled operator.

It also can take up a lot of floor space due to the amount of

residence time required for the bugs to digest the materials.

Evaporators: Can reduce wastewater to dry solids that can

be landfilled. Of course water re-use is not possible.

Evaporators have very high capital costs and consume huge

amounts of energy even for the most efficient models.

V✧SEP

Able to produce drinking water quality filtrate from any

wastewater. Extremely energy efficient and the vertical

design allows for a very small footprint. Does not require

pre-treatment or post-treatment for that matter. Wide range

of membranes available allow for precise separations based

on the process objectives. There is no chemical addition

required except for periodical membrane cleaning.

Suitability of V✧SEP for Oily Wastewater

As with other waste streams, volume reduction is the goal.

Hauling and disposal costs are king. Wastewaters normally

have very strict sewering rules and surcharges are attached

to anything that is sewered. Since Oil is normally limited to

100 ppm, oily wastewaters cannot be sewered and must be

taken care of in other ways. Oil can also not be landfilled as

long as it is a liquid. Therefore, disposal of oily wastewater

is an expensive operation. Volume reduction of the oily

wastewater will reduce the treatment costs to dispose of the

material. There are also many types of membrane solutions

for oil water separation. A common membrane device used

is a tubular membrane system. One common problem with

Tubular Membrane Systems is the permeate quality. V✧SEP

can offer competitive installed costs along with RO quality

permeate requiring less post treatment.

Concentration Polarization is Typical Sewer Discharge Limits:

the main limiting factor to

membrane filtration with oily

wastewaters. Therefore the

existence of a boundary layer

of highly concentrated oil and

solids next to the membrane

surface must be eliminated.

Spiral membranes employ

crossflow and fluid velocity

to accomplish this. Tubular

membranes use the same

technique with greater

efficiency. None of these has

the degree of efficiency of the

vibrating membrane surface

of V✧SEP which can use

both high crossflow velocities
as well as high vibrational energy at the membrane surface

which is oscillating back and forth 55 times per second.

Performance comparisons based on GFD of permeate flow

is difficult because there are so many variables to consider.

If all things are equal and the comparison is apples and

apples, V✧SEP will outperform the other membrane-based

technologies. Permeate flow rates will vary depending on

the initial concentration of oil and other materials in the

feed material as well as the % recovery which is being

achieved.

Compact Design

The V✧SEP Machine incorporates a modular design which

makes it compact. Because the basic design is vertical rather

than horizontal, the needed floor space per unit is inherently

less than other types of separations systems. The V✧SEP

does require up to 17’ in ceiling clearance. In most industrial

applications ceiling clearance is ample, it is floor space

which is limited.

Benefits of V✧SEP Compact Modular Design:

1] Easily added into an existing system to enhance performance

2] Can be installed in areas where space is at a premium

3] Is easily portable and can be moved from plant to plant

4] Can be installed as multiple stage systems or as single pass

5] Can be “chain linked” to an any number depending on demand.

6] More units can be installed as production grows.

Very often floor space is so limited, or the system being

designed is so large that a separate structure is built to

accommodate the treatment system. In such cases, the fact

energy efficient. In the largest model, the “Filter Pack”

contains 2000 Square Feet of membrane surface area, about

the size of a medium size house. This 2000 SF of membrane

has been installed into a container with a volume of about

15 Cubic Feet!!

Effects of Temperature

Temperature needs to be considered with regard to design.

Temperature can be used to increase filtration performance.

A stream that appears to be too expensive to filter at 25°C

may be well within the budget for a project at 40 or 50°C

even though you have a cost associated with heating the

feed. The reason is because increased temperature decreases

the viscosity of the liquid and enables the material to flow

through the membrane faster. It also makes it possible to

reach a higher endpoint solids because generally the material

remains more fluid at a higher temperature. As many streams

are water-based, the following table provides the viscosity

correction factors for water at various temperatures. The

be able to fit into an existing

area of the building or it will

reduce new building costs by

requiring less space.

Construction costs of $80 to

$120 $/square foot for new

industrial buildings can add up

and are a consideration when

figuring the overall cost

burden of completed systems

ready to use. In addition to the

limited space required for the

mechanical components, the

actual filter area has been

designed in such a way as to

be extremely compact and
following empirical relationships between viscosity and

temperature are based on measurements taken with

viscometers calibrated with water at 20°C.

0°C to 20°C

log10hT = ((1301)/(998.333+8.1855(T-20)+0.00585(T20)2)-1.30233

20°C to 100°C

log10(hT/h20) = ((1.3272(20-T)-0.001053(T-20)2)/

(T+105))

For example, if a wastewater stream had a flux of 110 GFD

at 25°C and you wanted to know what the flux would be at

50°C then you could set up the following ratio to give you

an estimate based on the change in viscosity.

(h @25°C)(Flux @25°C) = (h@50°C)(Flux@50°C)

 (0.8904)(110) = x(0.5468)

x = 179 GFD (@50°C)

reused in the process. The recovery ratio is the amount of

liquid, which is recovered as clean, permeate from the feed

flow. In other words, it is the ratio of liquid that passes

through the membrane versus what is fed to the membrane.

This is usually a critical factor for membrane filtration

because for a product dewatering or wastewater application,

a person is generally looking to remove as much of the water

as possible. There are two costs of higher recoveries: lower

flux rates and degraded permeate quality. These effects are

especially prevalent when you are reaching into the high

90% range. The average flux degrades because the feed side

solids increase as you recover more and more of the water.

In our filter pack, the feed enters through a pipe in the top

of the filter module and flows in a serpentine pattern

throughout the pack. The higher recovery does not affect

the flux at the top of the filter pack because that material is

almost always at the same concentration given a consistent

feed. However, the material at the bottom of the filter pack

will flux slower because it contains less water for removal

and more solids to impede the flow of liquid through the

membrane. The average flux is a time weighted average

across the entire filter pack. If the flux at the bottom of the

pack becomes slower then it will in turn lower the overall

average flux. The permeate quality degradation occurs in

These types of calculations can also be

completed for other materials given the

viscosity versus temperature relationships

for the feed liquid. As seen in the above

example, doubling the temperature nearly

doubles the flow rate. The result of this is

that it requires about half as much

equipment to do a filtration separation at

50oC as it would at 25oC. This means lower

capital cost as well as lower operating

costs. The V✧SEP has been designed to

withstand temperatures of up to 120oC

Volume Reduction

With Oily wastewater, hauling for disposal

is the conventional method of remediation.

Since hauling costs can be very expensive,

reducing the volume that needs to be

hauled can have a significant effect on

operating costs. V✧SEP is capable of

volume reducing wastewaters by up to

98% leaving a small amount to be hauled

and clean water that can be sewered or
the tighter ultrafiltration, nano-filtration and RO membranes

where there is rejection number based on % of molecules or

ions in the feed. Again as you remove more of the water,

the concentration on the feed side will increase and given

that the rejection of the membrane remains constant less

and less of the feed solids will be rejected. Those solids

will instead be passed through the membrane into the

permeate. For example, a 90% NaCl reject membrane will

still be rejecting 90% of the dissolved solids at perhaps a

60% recovery. However, beyond that recovery the permeate

quality will slowly deteriorate because the feed side solids

are increasing. Since 10% of the feed side solids pass

through the membrane (by definition a 90% reject

membrane), the amount of material which passes through

the membrane will increase. This material pollutes the

permeate. When the recovery is nearly the same as the

rejection then the system behaves as if there is no membrane.

Therefore, it is important to not only identify the membrane

and the desired recovery but also consider the economic

tradeoff between permeate quality and recovery.

Process Conditions

A process schematic for treatment of a typical oily

wastewater process using a V✧SEP system is presented in

the figure to the right. When the residual oily wastewater

has been settled so that oil and water can separate naturally,

the result is a process effluent, at 1.5 to 2% by weight total

solids (TS). This process effluent is normally sent to a multitrain chemical treatment step by a filter press or a dryer or an

evaporator in order to concentrate the solids to 60 to 65% by

weight. As you can see in the diagram, the addition of

V✧SEP to concentrate the process effluent improves the

process efficiency. The permeate can be reused in the process

or discharged.

solids (TSS), and a low level of total dissolved solids (TDS),

all well below the design requirements for process recycling

or discharge. Membrane selection is based on material

compatibility, flux rates (capacity) and concentration

requirements. In this example, the TSS reduction is over

99% while the oily waste is concentrated from a starting

feed of 1.5-2% to a final concentrate of 10% by weight.

The permeate quality from the V✧SEP can be controlled

though laboratory selection of membrane materials available

to fit the application parameters.

Successful pilot tests have been conducted at New Logic

for many kinds of oily wastewater treatment. Depending

on process temperatures, membrane selection and the

requirement for solids concentration or BOD/COD removal

for effluent streams, the permeate flux rate in the V✧SEP

can range from 15 to over 150 gallons per day per square

foot (GFD).

Economic Value

New Logic’s V✧SEP system provides an alternative

approach for oily wastewater treatment applications. In a

single operation step, V✧SEP will provide concentrated oil

sludge and also reduce BOD, COD, TSS, TDS and color to

provide a high quality permeate stream for discharge or reuse

in the process. In many applications, the addition of V✧SEP

will eliminate conventional treatment process requirements

and technologies without chemical treatment demands. The

justification for the use of V✧SEP treatment system in your

process is determined through analysis of the system cost

and benefits including:

Reduction of solids from discharge stream and the associated

treatment cost.

Reduction of BOD, COD, TSS, TDS and color for the

effluent stream.

Provision of high quality water for reintroduction into the

process.

Offset fresh water demands and pretreatment cost.

Retain heat in recycled process water as a possible method

to reduce energy requirements.

Elimination of biological growth, and odor in effluent.
