COD is the most popular alternative test to BOD for setting up the focus of natural and organic make any difference in wastewater samples.

Chemical Oxygen Demand (COD) is outlined as the level of oxygen equivalents eaten within the chemical oxidation of natural and organic issue by potent oxidant (e.g., potassium dichromate). The COD value signifies the amount of oxygen which is necessary with the oxidation of all natural and organic substances in h2o in mg/l or g/m3.

Be sure that the reagent blank vial is identical ton number as being the test vials. Take note: Not less than just one reagent blank must be run with Each and every set of samples with Each and every new great deal quantity of COD test vials.

The COD test is usually a practical measure of effluent high-quality of the wastewater treatment plant. It provides a quick, approximate measure of all chemically oxidizable substances and can be employed to identify efficiency difficulties in remedy amenities.
