Chemical Oxygen Demand (COD) What is Chemical Oxygen Demand (COD)? Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters. COD versus BOD

IMPORTANCE OF COD FOR WASTEWATER. Chemical Oxygen Demand is an important water quality parameter because, similar to BOD, it provides an index to assess the effect discharged wastewater will have on the receiving environment. Higher COD levels mean a greater amount of oxidizable organic material in the sample, which will reduce dissolved oxygen

present in the water and to measure the amount of dissolved oxygen consumed by. microorganisms during the biological reaction of oxygen with organic material. BOD is. commonly expressed in mg/L after 5 days of incubation at 20C.The greater the BOD value, the more rapidly oxygen is depleted in the water, therefore the lower the dissolved oxygen.

What is Chemical Oxygen Demand (COD)? Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters.

The Science of CHEMICAL OXYGEN DEMAND - Water Quality Testing . the dissolved oxygen content of a receiving water. COD Test The Chemical Oxygen Demand (COD) test uses a strong chemical oxidant in an acid solution and heat to oxidize organic carbon to CO 2 and H 2 O. By definition, chemical oxygen demand is “a measure of the oxygen equivalent
