Below this sort of oxygenated problems, microorganisms thrive, forming an Lively, balanced suspension of Organic solids—largely micro organism—identified as activated sludge. About six hours of detention is provided in the aeration tank. This provides the microbes ample time to absorb dissolved organics within the sewage, cutting down the BOD. The mixture then flows from the aeration tank to the secondary clarifier, the place activated sludge settles out by gravity.
