Hanna’s COD analyzer is a powerful multi-parameter
ion specific meter ideal for municipal water/wastewater treatment facilities.
The C 99 measures up to 36 parameters and is engineered
to be easy to operate and provide accurate, consistent results every time. C
99 along with Hanna’s C 9800 reactor
& pre-dosed reagents are all you need to perform simple COD
analysis in just a few short hours. The COD measurement
procedure is based on the well-established Closed Reflux Colorimetric Method
over 3
ranges: 0 to 150 mg/L, 0 to 1,500 mg/L and 0 to 15,000 mg/L. The
analyzer has been designed for ease of use by personnel at all skill levels.
It uses an advanced optical system, based on special tungsten lamps and narrow
band filters, for highly accurate, repeatable readings. There is no need
for
complicated programming or installation of delicate filters. Hanna’s
pre-dosed reagents reduce waste by minimizing the amount of necessary chemicals
to properly test COD levels. Hanna also offers a recycling
program to help with the safe and proper disposal of your reacted sample
materials.

About Chemical
Oxygen Demand (COD)
| COD
testing applied
COD is used as
a measurement of pollutants in natural and waste waters to assess the
strength of discharged waste such as sewage and industrial effluent waters.
It is normally measured in both municipal and industrial wastewater treatment
plants and gives an indication of the efficiency of the treatment process.
COD is measured in both influent and effluent water (before
and after treatment). The efficiency of the treatment process is normally
expressed as COD Removal, measured as a percentage of
the organic matter removed during the cycle.
COD has further applications in power plant operations, chemical
manufacturing, commercial laundries, pulp & paper mills, agriculture
& animal waste runoff, environmental studies and general education.
The C 99 colorimeter can be used in the laboratory setting
or field site testing by personnel at any skill level.. Back
to Top
Oxygen
Demand and COD
Untreated wastewater is generally rich in organic matter. This organic
matter feeds the bacteria and algae normally present in healthy water
sources. The presence of excessive amounts of nutrients discharged as
a result of untreated wastewater will cause an increase in concentration
of both bacteria and algae within the surface water. Beside organic matter,
wastewater also contains both organic and oxidizable inorganic compounds.
These organic and inorganic compounds directly and indirectly consume
the available oxygen present in the ecosystem. This process is called
eutrification and will eventually kill off other living organisms (plants,
animals, & insects) in the aquatic system.
Governments strictly control these oxygen demanding pollutants by setting
standards for maximum levels of “oxygen demand” for all discharged
wastewaters. There are different methods known for measuring the oxygen
demand but BOD (Biological Oxygen Demand) and COD (Chemical
Oxygen Demand) are the most widely accepted methods. The COD
test has many advantages over the BOD method. The COD
test is more accurate and faster than the BOD method. The BOD method requires
a five to seven day incubation period and is more subject to operator
errors. The COD method usually takes under three hours
and is easy to perform by technical and non-technical personnel alike.
Hanna’s COD method also uses a special anti-interference
agent that removes chloride interference. Back to Top
Official Reporting
Method
Chemical Oxygen Demand (COD) is defined as the
amount of specified oxidant that reacts with a sample under controlled
conditions. The quantity of oxygen consumed is expressed in terms of its
oxygen equivalent: mg/L of O2.
The Hanna COD method is based on the well established
Closed Dichromate-Reflux Colorimetric Method and is in accordance with
the two main official courses for chemical analysis in water and wastewater:
“Standard Methods for the Examination of Water and Wastewater”
(20th ed.) Method #5220D and “US Environmental Protection Agency,
Methods and Guidance for Analyses of Water” (2nd ed.) EPA Method
#410.4.
Furthermore, the US Environmental Protection Agency specifies that the
dichromate reflux method is the only method acceptable for reporting purposes.
The advantage in using this method includes highly accurate certifiable
results. Back to Top
The
Hanna COD System
The Hanna closed-reflux colorimetric COD system complies
with the EPA recommended method, and all other recommended applications
that are based on the potassium dichromate method. The individual components
of the system are designed to interface with existing closed-reflux colorimetric
test systems or to supply everything needed to perform simple COD
tests in a few hours.
Our pre-dosed reagents have been developed to minimize the amount of required
testing sample, reagent chemicals and the subsequent waste. Hanna has
taken special precautions to remove any potential interference that may
be caused by the presence of Chloride within the sample solution
As COD levels vary depending on the application and process
measuring points, Hanna offers reagents to cover three separate ranges.
Simply select the most appropriate range for the application. Each box
of 25 vials is supplied with a Reagent Quality Certificate
produced by our quality assurance team. The reagents are traceable to
NIST SRM® 930e.
HI 93754A Low Range 0-150 mg/L
HI 93754B Medium Range 0-1500 mg/L
HI 93754C High Range 0-15000 mg/L
The organic and inorganic compounds present in the water sample are oxidized
under strong chromic acid conditions during a two-hour digestion period
at 150°C in a preheated reactor.
The Hanna reactor C 9800 is a block heater type with
an accurate temperature control system to ensure the digestion temperature
is exactly 150°C ±2°C as required by Standard Methods.
The C 9800 features a user-selectable timing mode (timed
or infinite) and an acoustic alarm to alert the user that the digestion
period is complete. In the timed mode, the reactor automatically switches
off after the digestion has completed. During the digestion period, your
safety is guaranteed using the HI 740217 protective shield.
After digestion, remove the vials from the reactor and place them in the
HI 740216 cooling rack. When the vials are cooled down to about
room temperature, direct COD readings can be obtained
with the C 99 COD analyzer. Using the closed-reflux colorimetric
method has many advantages over conventional methods.
With the Hanna COD solution, no volume correction is
necessary after digestion. The colorimetric method is also advantageous
because you are not required to perform time intensive and reagent consuming
titrations as with other methods.
The C 99 multi-parameter photometer is a high precision
instrument with an advanced optical system. A special microprocessor controlled
