Sludge Thickening - an overview ScienceDirect Topics

X.A Thickening. The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2 to 5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation.
