Oxygen Demand (EOD)
Description:
Oxygen demand studies are performed to determine the degree of pollution in an effluent of a sewage plant or a body of inland water. Oxygen Demand is differentiated into biochemical oxygen demand (BOD, German: BSB) and chemical oxygen demand (COD, German: CSB).
Biochemical Oxygen Demand is a measure of the oxygen requirement in microbial oxidation of organic substances contained in water. Usually BOD5 (5 days continuous measurement at 20°C in the dark) is reported.
Chemical Oxygen Demand is a measure of the amount of oxygen required to oxidize organic and oxidizable inorganic compounds in water and wastewater. The amount of oxygen is provided by the addition of potassium dichromate.
