Under these kinds of oxygenated problems, microorganisms thrive, forming an Lively, balanced suspension of Organic solids—mostly bacteria—called activated sludge. About 6 hours of detention get more info is supplied while in the aeration tank. This offers the microbes sufficient time to soak up dissolved organics in the sewage, decreasing the BOD. The combination then flows from the aeration tank into your secondary clarifier, where activated sludge settles out by gravity. Apparent water is skimmed with the surface area with the clarifier, disinfected, and discharged as secondary effluent.
