Sludge treatment − gravity thickening | Sludge Processing
2020-6-18 · Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross-sectional area.

What is the Sludge Thickening Process in Water Treatment ...
2018-3-6 · Gravity thickening involves using specially designed circular tanks that concentrate thin sludges to a more-dense sludge product. The limitation of this form of clarification water treatment is that it works mostly for the excess watery sludge derived from an activated-sludge process. Thickening tanks have slow-moving vertical paddles.
Details
Thickening | Sludge Processing
Thickening. Thickening processes are those which concentrate the sludge by removing part of the free water, i.e. the water not associated with the sludge particles or flocs. In doing so, the finished product retains the liquid, free-flowing characteristics of the feed sludge, so that it can still be conveyed by pumping.
