Bod of wastewater is estimated by measuring
WebBiochemical oxygen demand (BOD) is a measure of the dissolved oxygen consumed by microorganisms during the oxidation of reduced substances in waters and wastes. Typical sources of BOD are readily biodegradable organic carbon (carbonaceous, CBOD) and ammonia (nitrogenous, NBOD). WebBiochemical Oxygen Demand ( BOD) can be estimated from Chemical Oxygen Demand ( COD) measurements, if a correlation is established. COD values are almost always higher than BOD values for...
