WebMar 19, 2024 · They settle at the base of a primary settlement tank. After this, the water enters a chamber of grit where the grit is extracted. To minimise heavy deposits in aeration tanks and channels, grit removal is necessary. By the anaerobic process, the sludge is constantly reduced in density. Primary settling tanks are the next step. WebAfter the sewage leaves the settling tank in the primary stage, it is pumped into an aeration tank, where it is mixed with air and sludge loaded with bacteria and allowed to remain for several hours. During this time, the bacteria break down the organic matter into harmless by-products. The sludge, now activated with additional
