WebJul 19, 2016 · Biochemical Oxygen Demand • As the microbial activity depends on temperature, BOD test is highly depends on temperature. • Generally this temperature is chosen as 20⁰C or 27⁰C. 12. Biochemical Oxygen Demand 60-70% 95-99% Variation in … WebBiochemical oxygen demand (BOD) is a measure of the dissolved oxygen consumed by microorganisms during the oxidation of reduced substances in waters and wastes. Typical sources of BOD are readily biodegradable organic carbon (carbonaceous, CBOD) and ammonia (nitrogenous, NBOD). WebThe estimate based on the [BOD5] value is based upon the exponential (first-order) nature of oxygen demand. The ultimate carbonaceous oxygen demand is than Ultimate-CBOD … can i do stock trading with fidelity
