Aerobic treatment process utilizes a mixed population of microorganisms to oxidize biodegradable organic material in the presence of oxygen. The bacteria convert the organic matter in the wastewater to gases (CO2, NH3), and new bacterial cells (C5H7NO2).

There are several different options for the aerobic treatment process, such as the activated sludge process, aerated lagoons and the sequencing batch reactor.

Selection of the process depends on wastewater strength and effluent criteria.
