Overview

Sludge Thickening an overview | ScienceDirect Topics

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 2–5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation. A gravity thickener is shown in Figure 10. The
