3 Common Tests to Determine Organic Pollution in Wastewater

Web27 feb. 2015 · During algal blooms, approximately 70-80% of the effluent BOD is due to the presence of algae. Therefore, the overall performance of a facultative lagoon cannot be properly measured if algae contribute to effluent BOD and TSS. Long retention times in facultative lagoons provide an optimal condition for algal growth. WebBOD is an abbreviation for “biochemical oxygen demand.” This term is used to describe the amount of oxygen that is required to break down organic matter in water. The higher the BOD level, the greater the pollution present in the water. This makes it an important indicator of water quality. include in autism
