Bod of waste water is estimated by
WebBiological oxygen demand (i.e., BOD) is measured by the amount of oxygen that would be consumed when all the organic matter in one litre is oxidized by bacteria. Thus, the BOD of waste water is estimated by measuring … WebBOD of wastewater effluents is used to indicate the short-term impact on the oxygen levels of the receiving water. BOD analysis is similar in function to chemical oxygen demand(COD) analysis, in that both measure the amount of organic compoundsin water.
