Wastewater needs to be monitored closely to prevent environmental pollution and human illness.

Oxygen Demand and CODChemical Oxygen Demand (COD) is defined as the amount of specified oxygen that reacts with a sample under controlledconditions. The quantity of oxygen consumed is expressed interms of its oxygen equivalent: mg/L of O 2.

The HANNA COD method is based on the well established closeddichromate-reflux colorimetric method.

Moreover the US Environmental Protection Agency (EPA) specifiesthat the dichromate reflux method is the only methodacceptable for reporting purposes . The advantage in using thismethod includes certifiable results as well as high accuracy.

COD Testing ApplicationsCOD is used as a measurement of pollutants. It is normallymeasured in both municipal and industrial wastewater treatmentplants and gives an indication of the efficiency of the treatmentprocess. COD is measured on both influent and effluent water. Theefficiency of the treatment process is normally expressed as CODRemoval, measured as a percentage of the organic matter purifiedduring the cycle. COD has further applications in power plantoperations, chemical manufacturing, commercial laundries, pulp

and paper mills, agriculture and animal waste runoff,environmental studies and general education. HANNA equipmentcan be used in the laboratory or for on-site testing. Themeasurement procedure has been designed for ease of use bypersonnel at any skill level.

Monitoring examples:

Beyond COD:Nitrogen and PhosphorusThe goal in Wastewater Treatment is not only COD reduction, butalso to control Nitrogen and Phosphorus, which are responsible foreutrophication phenomena in natural environments. COD,

Nitrogen, and Phosphorus control are performed not only to obeyenvironmental protection laws, but also to optimize plant costs.

Effective monitoring and control of parameters such asammonia, nitrate, total nitrogen and total reactivephosphorus allow plant managers to profile and improvethe health of aquatic ecosystems. By accurately monitoringlevels of each specific pollutant, operational parameters canbe adjusted to maintain high efficiency of biodegradationtreatments while also minimizing costs.

NitrogenWhen a treatment plant uses processes like nitrification anddenitrification, it is important to monitor and maintain the

equilibrium between Ammonia Nitrogen, Nitrate and Total Nitrogen during the bio-treatment. The nitrogen level is importantbecause it relates to the quantity of oxygen provided in thenitrification area. Ammonia is also controlled because it canbecome very toxic for the bacteria responsible for denitrification.

Phosphorus

Phosphorus is measured during both biological and chemical dephosphorization. An excessive amount of phosphate dischargedin superficial waters or in bio-treatment tanks causes an increaseof algae and system eutrophication

less than what you may have been paying.

All this and much more at a fraction of the cost of expensive and

complex spectrophotometers!

Measurement ProcedureThe entire COD measurement processhas been designed for ease of use bypersonnel at any skill level. Inaddition, all HANNA equipment hasbeen designed for maximum safetyduring handling and testing with aminimum amount of waste. Even anovice can safely run accurate CODtests in just 3 simple steps: 1. Fill the pre-dosed

vial with the sample2. Place the vial in the

HI 839800 reactor(sold separately)and set the timer

3. Place the vial in theHANNA HI 83099and read the results

Easy COD measurement HI 83099 multi-parameter photometer ispre-calibrated to measure COD levels at threeranges at the touch of a key pad. Simply usethe scroll button to select the desired rangeand begin reading. HI 83099 automaticallyselects the correct wavelength for thechosen range.

Outstanding measurement quality HI 83099 employs an advanced opticalsystem, assuring high accuracy measurementsthroughout the entire range. The opticscombine the power of a miniature lightsource with the precision of a narrow bandinterference filter.

Save space in your laboratory.The compact size of the HI 83099photometer allows the user to eliminate theclutter of bulkier and more costlyspectrophotometers currently being used.Measuring 23 x 17 x 7 cm and weighing lessthan 700 grams, HI 83099 can betransported with ease from place to place.

Certified COD ReagentsHANNA COD reagents are available in the following formats:

Each box of 25 vials is supplied with a HANNA certificateof quality.

The reagents are traceable to NIST SRM 930.

HANNA also produces mercury-free reagents to be used foranalyzing samples without chloride.

Notes:* Method with chromium-sulfuric acid is officiallly recognized by EPA for wastewater ana** The HI 93754F-25 and HI 93754G-25 method follows the official method ISO 15705.*** This method is recommended for general purpose analysis with no chloride interferance.

CODE METHOD RANGE

HI 93754A-25 EPA* 0 to 150 mg/L

HI 93754B-25 EPA* 0 to 1500 mg/L

HI 93754C-25 0 to 15000 mg/L

HI 93754D-25 Mercury-free*** 0 to 150 mg/L

HI 93754E-25 Mercury-free*** 0 to 1500 mg/L

HI 93754F-25 ISO** 0 to 150 mg/L

HI 93754G-25 ISO** 0 to 1000 mg/L

Three measurement ranges to satisfy each need As COD levels vary depending on the application and processmeasuring points, HANNA offers reagents to cover three separateranges. Simply choose the best range for your application:

low range: 0 to 150 mg/L O 2medium range: 0 to 1500 mg/L or 0 to 1000 mg/L O 2high range : 0 to 15000 mg/L O 2

Accurate and repeatable measurementsHANNA COD reagents have been developed in accordance withStandard Methods 5220D, USEPA 410.4 and ISO15705:2002 methods.

Pre-dosed vialsHANNA vial contains approx. 3 mL of pre-dosed reagent. The operator

just needs to add a small quantity of the sample - 2 mL for LR and

MR, and 0.2 mL for HR analysis. Quick and accurate measurements

With pre-dosed vials test preparation time is dramatically reduced.There is no time-consuming reagent preparation procedure orglassware cleaning.

Safe reagentsHANNA COD reagents are safe for operators and the environment. Vialsand caps have been designed to avoid accidental reagent spills. Thanksto the pre-dosed reagents, the amount of chemicals is minimized.

Tailor-Made AccessoriesThe following accessories and spare parts have been specially designed for COD analysisto make your measurements simpler and safer.

Quick Chloride TestsThe HI 3898 test kit, developedaccording to the ISO 15705:2002 method,determines chloride concentration.

This very important test is recommendedby ISO, since an excessive presence of chloride can interfere with the COD analysis.

The test gives a fast YES/NO reply to thequestion if chloride will interfere with theCOD analysis. If chloride concentration isgreater than the official maximum level,the solution turns yellow and the sampleneeds to be diluted before performing theCOD test, otherwise if the solution isorange-brown, the sample doesnt need tobe diluted.

The maximum level allowed is 1000 ppmof Cl - following ISO methods, or 2000 ppm

of Cl - for US EPA, APHA, AWWA and WEmethods.
