Wastewater Biological Treatment Methods in Municipal Plants The biological treatment of wastewater is a major component of municipal wastewater treatment plants, which are intended to eliminate organic pollutants and nutrients using the natural biological treatment. In these systems, microorganisms like bacteria and protozoa are used to break down biodegradable organic substances that are found in sewage. The biological treatment is normally conducted at the secondary treatment stage whereby the Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) reductions are realized.
