Under such oxygenated problems, microorganisms thrive, forming an active, healthier suspension of biological solids—mostly bacteria—named activated sludge. About 6 several hours of detention is provided from the aeration tank. This gives the microbes more than enough time to absorb dissolved organics through the sewage, lessening the BOD. The mixture then flows in the aeration tank in to the secondary clarifier, the place activated sludge settles out by gravity. Apparent water is skimmed through the floor on the clarifier, disinfected, and discharged as secondary effluent.
