Biochemical oxygen demand bod คือ
WebBiochemical Oxygen Demand (BOD) The BOD is an important parameter for assessing water quality. It deals with the amount of oxygen consumption (mg O 2 L − 1) by aerobic biological organisms to oxidize organic compounds. Sewage with high BOD can cause a decrease in oxygen of receiving waters, which in turn can cause the death of some … WebThe test for biochemical oxygen demand (BOD) is a bioassay procedure that measures the oxygen consumed by bacteria from the decomposition of organic matter (Sawyer and McCarty, 1978). The change in DO concentration is measured over a given period of time in water samples at a specified
