Webb7 apr. 2024 · Sedimentation is the process that allows the different particles which are in the suspended form in water to settle under the gravitational effect. The particles which settle out from the suspension become the sediment, while in water treatment this is known as sludge. When this thick sediment continues to settle, this is called consolidation. WebbThe sludge concentration at the bottom of the secondary sedimentation tank is very low, not much higher than that in the aeration tank. The loss of sludge leads to the quality of the effluent exceeded. There is a small amount of filamentous bacteria in the sludge microscopic examination.

WebbSludge Bulking: The sludge which does not settle well in sedimentation tank is called as bulking sludge. It may be due to either (a) the growth of filamentous microorganisms which do not allow desirable compaction; or b) due to t( he production of nonfilamentous highly hydrated bio- mass. There are many reasons for sludge bulking.

Sedimentation is a physical water treatment process using gravity to remove suspended solids from water.
