Sludge sedimentation tank
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 tank with … WebbThe principle of shallow depth sedimentation has been extended to the design of a parallel plate system, sometimes referred to as lamella clarifiers. Clarifiers using the plate system are usually purpose built to take advantage of the high settlement rates which can be obtained and the greater density of sludge provided.
