Sludge Thickening an overview ScienceDirect Topics

Softener sludge is rarely thickened because it concentrates well in the clarifiers. If necessary, it can be further thickened to 20–30% w/w or more at a dry solids loading rate of about 8 kg/h.m 2. To prevent the softener sludge becoming too thick, underflow is sometimes recycled to the feed.
