Measuring principles
Nowadays, if for example you need tomeasure nitrate or ammonium online,
you will often have a tough time
deciding what analysis principle thedevice should use. It’s an important
decision because an unsuitablemeasuring principle can lead toseriously incorrect measurements.
On the other hand, no generalrecommendation can be made for ameasuring principle that is ideallysuited to every application.

The question is more what themeasurement results are to be usedfor:
• If the focus is on control andregulation strategies, you needfast measured values that reflect
the current conditions in theprocess. These rapid measured
values are mostly returned by
sensor systems that are useddirectly in the process. They work
based on optical or potentiometricmeasuring principles.

• If monitoring and documentation
tasks are to be performed, highprecision, self-cleaning analyzers
that are automatically calibrated
are the solution. Such types ofmeasuring systems are basedon colorimetric, wet-chemical,
biological or potentiometricmeasuring principles.
Endress+Hauser’s unique complete
product range always offers you theright device with the right measuring
principle for your application.

Photometric methods
Photometry is one of the oldest andmost time-tested analysis procedures
there is. It is based on the fact thatdifferent substances contained in an
aqueous sample absorb, or filter out,
different amounts of light introduced
into the sample. Detectors on thereceiver side of the measuring systemanalyze this difference between
the light introduced and the lightreceived, and use the calibration
curve saved in the system todetermine the concentration of thespecific substance in the sample.

The majority of all the measuringsystems available today works
on the basis of photometricmeasuring principles:

Colorimetry measuring principle
One or more reagents are added
to the water sample to “dye” thesample to be analyzed. Afterwards,
the aqueous sample is measured byphotometric means. The intensityof the specific absorption signal is
proportional to the concentration of
the dyed substance in the sample.
A reference measurement (sample
without chemicals) is taken before
every measurement to be able tocompensate for any interference
caused by inherent color, turbidity
or contamination. The actual
concentration of the substance isascertained using this information.

Most standardized
procedures for water andwastewater inspection
are based on photometry
and colorimetry. By
specifically selecting
the dye reagents, manydifferent parameters can bemeasured very accurately,
ranging from aluminumand silicate to phosphate.

Video on thecolorimetricmeasuring principle

refer to optical measuringsystems here that usually analyze
a measuring wavelength anda reference wavelength.

• Colorimetry: using special reagents,
the initially invisible particles are“dyed” and the dyed substances arethen measured photometrically.
• UV absorption: The substances
to be measured display direct
self-absorption in the ultraviolet
range of the light. People often• UV-VIS spectrometry: The
spectrometer measures in the
wavelength range from 200 nm
up to 800 nm and determines thesubstance-specific absorption of thisradiation.The measured absorption
at specific wavelenghts is used
to calculate the concentrationof various parameters.

Absorption	= measurement of the attenuation of light
relative to the introduced light intensity

Measuring principles

Measuring principle: UV absorption
UV sensors use the self-absorption of the substance thatis to be measured in the ultraviolet range of the light.
For this purpose, the ultraviolet light of a pulsed, highly
stable flash lamp is shone through the measurement
section. The substances in the sample which are to
be measured absorb this light in proportion to theirconcentration. The intensity of the attenuated beam oflight is measured at two fixed wavelengths (measuring
wavelength and reference wavelength) using photodiodes.
Interference from turbidity, contamination or otherorganic hydrocarbons is eliminated mathematically.
The substance concentration is determined with theaid of a calibration curve saved in the system.
The Viomax CAS51D in-situ sensors for measuring nitrateor SAC work on the principle of UV absorption. The
sensors measure directly in the process. Nitrate and SAC(sum parameter for the organic load of the water) absorb
directly in the UV range without reagents being added.
Measuring principle: UV-VIS spectrometry
Spectrometry uses the interaction of light with substances.
Electrons or molecules are excited by specific wave lengths
and absorb them so that the detector measures a lower
intensity of these wave lengths. In case of spectrometry,absorption is measured at several wave lengths andcorrelated to the concentration of several substances suchas COD, SAC, nitrogen, TOC, turbidity, color APHA/HAZEN
etc. using data models.

Potentiometric method with ion-selective electrodes (ISE)
Potentiometric measurement using ion-selective electrodes
is similar to pH measurement. The heart of the ionselective electrode (ISE) is a membrane that is selective forthe specific ion to be measured. Ionophores areaccommodated in this membrane. These ionophores
facilitate the selective “migration” of the ions to the insideof the electrode and this change in charge causes anelectrochemical potential. This potential is measured
against a separate reference electrode with a constantpotential. It is proportional to the ion concentration in themedium. With this measuring principle, the measurement
result is not affected by the color and turbidity of themedium. Since the ISE sensor is immersed directly into themedium and responds rapidly, the measuring system reacts
very quickly to changes in concentration. The measuring
signal and concentration of the measured ions are directly
related over a very broad range in such a way that thesesystems can cover a very wide measuring range.

Applications

Description
In addition to reducing carbon, modern wastewater treatment
plants also reduce nitrogen and phosphate. For this purpose, online
measurement of the following parameters is required:• Ammonium• Nitrate• Nitrite• Phosphate
Online analysis helps in meeting the more stringent discharge limit
values and in reducing operating costs, for example wastewater
discharge costs.

Applications............................................................................................................

Description
Sum parameters are mainly used to measure and assess the organic
load of water and wastewater:• Spectral absorption coefficient (SAC)• Biological oxygen demand (BOD)• Chemical oxygen demand (COD)• Total organic carbon (TOC)• Total phosphorus (TP)• Total nitrogen (TN)Applications............................................................................................................

Description
The requirements for water quality differ depending on the industry.
Drinking water and most of the process water is, however,chlorinated, softened and/or chemically conditioned for setting thepH value, corrosion control and for preventing sludge buildup.
Practically all manufacturing processes require corrosion-free water,which shows neither turbidity and color nor contains iron andmanganese. Microbiological growth is also to be avoided.
The following parameters are measured:• Aluminum (Al) • Hardness (Ha)• Chromate (Cr)• Silica (Si)
• Iron (Fe)• Sodium (Na)Applications............................................................................................................

Sample conditioning
Correct sample conditioning is part and parcel of every analysis.
Good sample conditioning should:• Not alter the sample• Retain all the particles etc. that cause interference• Require minimum maintenanceThis is particularly important in the wastewater industry.

Double-batch operation
The patented doublebatch operation links thewater and the gas circuits.
The aqueous sample iscontinuously preparedin the analyzer and fed
batch-wise into the furnace.
During measurement,
the gas containing CO2 iscirculated and accumulated
in the gas circuit. This
makes it possible to record
large sample volumes(1200 µl) which leads
to high sensitivity. Aftermeasurement, the gas
circuit is flushed with
CO2-free carrier gas
and the basic line forthe next measurement
is determined.

Heatable salt trap
• With the heatable salt trap, the majority of volatile salts
precipitate in the salt trap and not in the furnace.
• The furnace does not have to cool down before
maintenance is performed on the salt trap. This increases
the availability of the measuring point dramatically.
• It only takes 5 minutes to clean or replace the salt trap.

UV oxidation and measurement ofdifferential conductivity
While the medium flows through the
UV reactor, the organic substances areoxidized to CO2 by short-wave UV
radiation. The dissolved CO2 causes anincrease in conductivity via the
carbonic acid balance due to theformation of hydrogen carbonate. This
increase is measured by electrodepairs upstream and downstream of
the UV radiation and is converted to
TOC.

Sodium and silica measurement with CA76NA and Liquiline System CA80SI

Silica and sodium are two coreparameters for the water quality inpower plants. The maximum silica
content permitted in boiler feedwater
is often contractually agreed on
between turbine and boiler suppliers
and power plant operators. Increased
silica and sodium concentrations canlead to deposits on turbines, boiler
walls and heat exchangers that havean adverse effect on a power plant‘sefficiency and can even cause
damages of the expensive plant
equipment. In addition, accurate silica
and sodium measurement provides an
early indication of condenser leakages
or exhaustion of the ion exchanger
bed.

Preliminary sedimentation
During primary treatment, the wastewater is separated
into „generally liquid substances“ - the water part - and„generally solid substances“ - the sludge part. The waterpart contains organic carbon as well as nitrate andammonium. These are known as nutrient parameters.

Denitrification and recirculation
Wastewater and activated sludge are merged during thisprocess. If oxygen is not present, nitrate is reduced to basic
nitrogen. This is the first step in the biological treatment
process. Carbon serves as a source of nutrition for thebacteria and is also reduced.

What is measured?
• TOC and SAC measurements provide
information on the carbon load entering theplant > CAS51D, CAS80E, CA72TOC• Ammonium measurement provides information on theamount of nitrogen in the wastewater. This nitrogenalso has to be digested in the biological treatment
phase > CAS40D, CA80AM with CAT860, CA80TN• Sampling enables a detailed analysisof the introduced water.

What is measured?
• The measured COD value provides information on theamount of carbon in the biological treatment process> CA80COD, CAS51D, CAS80E• Nitrate measurement indicates the nitrate nitrogen
which is reduced during this stage of the process> CAS51D, CAS80E

These measurements taken prior to sludge activation
make it possible to detect load spikes and to
redirect these into buffer basins. Their subsequent
return to the wastewater treatment process allows
for safe and smoother system operation. The
discharge values can be maintained at any time.

Preliminary sedimentation

The next stage of the treatment process can commence assoon as the nitrate is processed. A low concentration of
nitrate in the denitrification stage is essential to achieving
low concentrations in the outlet and thus reducing
wastewater charges. By determining values for the sludge
parameters it is possible to optimally control the sludge
process.

Nitrate,

Denitrification

Liquid analysis – Water & Wastewater

OutletAfter biological treatment, the wastewater settles inthe secondary clarifier. The sludge settles on the floor
and can be reused as activated sludge or surplus sludge.
The clear water is drawn off and directed as clean water
into public bodies of water via the drainage canal.

Nitrification
During the nitrification stage, oxygen is used to reduce theremaining ammonium to nitrate. Some of the wastewater
is returned to the denitrification stage for further nitrate
reduction and to „inoculate“ the fresh wastewater.
What is measured?
• The ammonium measurement indicates
how much ammonium has been reduced> CAS40D, CA80AM with CAT820• Oxygen is measured to help regulate and control
the efficiency of the reduction process. Too
little oxygen slows down the process while toomuch drives up operating costs > COS61D• Orthophosphate measurement is used to regulate
and control the dosing of precipitants > CA80PH with
CAT820
Aeration accounts for up to 70% of the power used inbiological wastewater treatment plants. Sensors forammonium, nitrate and oxygen can reduce aerationand thus lower the energy consumption of the plant.

What is measured?
In clear water:• Ammonium and nitrate measurements are indicatorsof the ability of the wastewater treatment plant to
reduce the nitrogen load > CA80AM, CAS51D• SAC, COD and TOC measurements document
the degradation efficiency of the wastewater
treatment plant with regard to the carbon
load >CAS51D, CA80COD, CA72TOC• The measurement of phosphate in the form of PO43or Ptot provides information on the rate ofphosphate removal > CA80PH, CA80TP• Sampling in combination with comprehensive quality
monitoring proves compliance with legal discharge limits
Continuous monitoring of the discharge values ensuressafety. Complete documentation can be used as proof ofwastewater treatment performance to the authorities, andalso for internal monitoring purposes. As the sludge profile
is monitored, changes caused by a heavy downpour, forinstance, can be detected quickly and countermeasures
can be taken.

Untreated water
Water from different sources carries with it different
loads. For example, water from springs and wells
contains particles; surface water contains additional
biologically active elements; and process water fromindustrial processes contains chemicals. The aim here isto ascertain the quality of the untreated (raw) water:Industrial water treatment
The water passes through various stages in thetreatment process: substances causing turbidity are
removed by flocculation and gravel filters; oxygen is
added to oxidize iron; and the pH balance is regulated.
The resulting water is now the basis for drinking
water. It is also used as process water in industry.

What is measured?
• Physical variables such as the pH value, turbidity andconductivity, and the organic load SAC, TOC and derived
variables provide information on the usability of theuntreated water > CM44, CAS51D, CAS80E, CA72TOC• Nitrate - when converted to nitrite - can cause toxicity

Drinking water treatment
The treated water is pressurized or pumped into anelevated tank. Depending on the conditions, chlorine
is injected into the pipe as a disinfectant and thewater is then fed into the drinking water system.
The water quality undergoes a thorough analysis at
the waterworks outlet.

Ultrapure water treatment
Ionic salts are removed from the treated water. The water issoftened and gas is removed. This results in ultrapure water

No contamination of feed waterHigh quality of boiler feedwater is a key factor
to avoid corrosion or build-up of deposits inboilers or pipes. They might lead to expensive
repairs or even complete unit replacement.
Conductivity, pH and oxygen sensors,
specially designed for trace measurement,
ensure that even minute impurities in thedemineralized feed water are detected. Plant
operators can react fast and take necessary
measures.
Safe cooling water cycles
Cooling water cycles must run stably and must
not interfere with the product. Contaminatedcooling medium can cause corrosion orbuild-up of deposits and thus leakage in thecooling water cycle that leads to mixing ofproduct and cooling medium. Conductivity,
pH, chlorine and SAC sensors ensure that
contamination is detected before problems
can occur.
Cooling water must be of such quality that no
micro organisms can settle in the system. They
form a biofilm on the pipes that impedes theheat transfer and thus limits the cooling
performance. Reliable chlorine measurement
enables precise chlorine dosing leading tobacteria-free water.
