WebBiochemical Oxygen Demand(BOD), representing the biodegradable organic load in water, is a prime parameter to assess water quality. Estimation of biochemical oxygen demand requires prolonged incubation of water samples. Thus, it is a time-consuming as well as energy-consuming process. WebThe BOD test measures the oxygen demand of biodegradable pollutants whereas the COD test measures the oxygen demand of oxidizable pollutants. The so-called 5-day BOD measures the amount of oxygen consumed by biochemical oxidation of waste contaminants in a 5-day period.
WebJan 1, 2014 · 2.2 BOD: Biochemical Oxygen Demand BOD is the amount of oxygen demand for microorganisms to oxidate and stabilize dissolved organic or inorganic substances in water under certain conditions. Bacteria use dissolved oxygen (DO) for decomposition of organic matter and as a result DO will be reduced. WebDissolved oxygen (DO) is one of the most important parameters in aquaculture. Maintaining good levels of DO in the water is essential for successful production since oxygen (O 2) has a direct influence on feed intake, disease resistance and metabolism. A sub-optimal level is very stressful for fish and shrimp.
WebBOD is calculated by using the formula BOD = (D1 – D2)/P Where, D1 = initial dissolved oxygen concentration. D2 = fifth day dissolved oxygen concentration. P = volumetric fraction of wastewater. BOD values range from 1 mg/L for natural waters to about 300mg/L for untreated domestic sewage waters.
