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 … WebN-BOD means Nitrogenous Biochemical Oxygen Demand BOD5 typically includes C-BOD and N-BOD unless one or the other is inhibited. What are the main differences of C-BOD vs. BOD5? There are too many terms and it is getting confusing to me. . . . . There are two completely different tests-a C-BOD test and a BOD5 test.
WebJun 19, 2015 · COD is the amount of oxygen required to chemically breakdown the pollutants. Whereas BOD is the amount of oxygen required to do this biologically through micro-organisms. There is a strong correlation between COD and BOD, however COD analysis is a much faster and more accurate method. Clean Water. WebJun 18, 2024 · Traditional BOD, COD, TOC and DOC parameters are time consuming and expensive tests for measuring organics in water as per above, making them impractical to use for process control applications.
