WebCOD versus BOD Like COD, biochemical oxygen demand (BOD) measurement can be used to estimate the amount of pollution in a water sample. COD describes the amount … WebBOD can be broken down into two components: Carbonaceous BOD (CBOD) and Nitrogenous BOD (NBOD). COD is Chemical Oxygen Demand, which includes all forms of BOD plus other non-biological oxygen demands. Total BOD includes all CBOD plus NBOD, but some regulatory authorities specifically call for the CBOD5 test instead of the …
WebFeb 3, 2024 · 0. Biochemical oxygen demand (BOD) is a way to assess the amount of oxygen required for aerobic microorganisms to decompose the organic material in a sample of water over a specific time frame. It is the oxygen uptake demand of a source of water. Carbonaceous biochemical oxygen demand (CBOD) is the same method as BOD, but … WebNov 11, 2024 · BOD and COD methods differ from TOC because they measure the amount of oxygen that is depleted by organic species in water. Moreover, TOC is a measure of all carbon (both organic and inorganic), rather than the oxygen that is reduced by these species. As written by a TOC manufacturer, “ TOC on its own sheds no light on the …
Web1- BOD is a biological oxidation process in wastewater or water while COD is chemical oxidation process. 2- Biological Oxygen Demand is performed by using aerobic organism but Chemical Oxygen Demand is performed by using re-agents of chemical. 3- BOD test happens on sealed water preserved for a period of 5 days and 20 degree Celsius … WebThe fundamental distinction between BOD and COD is that BOD refers to the quantity of oxygen consumed by bacteria during the aerobic decomposition of organic matter, …
