How does chemical oxygen demand work

WebBiochemical oxygen demand (BOD) is the amount of oxygen microorganisms require to break down organic materials. In contrast, chemical oxygen demand (COD) is the amount of oxygen required to break down the organic material via oxidation. Read: Biological Oxygen Demand Let us look at the differences between BOD and COD. WebAnswer: a) BOD₅ = (D1-D5) / P = (9.0-3.0) / 0.030= 200 mg/L b) BOD₅ = Lo (1 – e-kt) So, L0 = BOD5 / (1- e-kt) = 200 / (1-e-0.22x5) = 300 mg/L c) After 5 days, 200 mg/L of oxygen …
