Cod and bod calculation
WebCOD versus BOD Like BOD, chemical oxygen demand (COD) can be used to estimate the amount of organic loading in a water sample. COD describes the amount of oxygen … WebBOD is oxygen demand for oxidation of organic matter by micro organism. COD is oxygen demand for oxidation of organic and non biodegradable organic matter. COD is always greater than BOD hence the ratio will be always greater than 1. If BOD/COD is 0.92 to 1, waste water is fully biodegradable. If BOD/COD > 0.63, difficult to biodegardable.
