Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are important parametters used to o evaluate thee effectiveness of waterwater treatent plants. They measure thee measure thof organic matter in water, indicating how well a plant removes accordants before releasing water back into te environment.

Understanding BOD and d COD

BOD measures thee equirt of oxygen that microorganisms require to o decopose organic material in water over a specic period, usually five days. COD quantifies that total equirt of oxygen need dead to chemically oxidize organic and inorganic substances in water. Both remerters help assess water quality and carement accessy.

Calculating RemovalEfficiency

Te embale accessiency of BOD or COD is calculated using thee following formula:

CLAS1; CLAS1; CLAS3; CLAS3; Efficiency (%) = CLAS1; (Influent value - Effluent value) / CLAS3; × 100 CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLASPERASPERASPERASPERASPERASPERAL;
