DETERMINATION OF CHEMICAL OXYGEN DEMAND COD
DETERMINATION OF CHEMICAL OXYGEN DEMAND COD

Chemical oxygen demand does not differentiate between biologically available and inert organic matter, and it is a measure of the total quantity of oxygen required to oxidize all organic material into carbon dioxide and water. ,COD, values are always greater than BOD values. For domestic and some industrial ,wastewater COD, is about 2.5 times BOD.
