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 to 5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation.

Sludge Thickening - an overview ScienceDirect Topics

Generally, the thickening process can remove the pore water in sludge and reduce the moisture content to about 95 %. The purpose of conditioning is to improve the sedimentation and dehydration properties of sludge by changing its microstructure. Although the pore water can be removed by thickening, the volume of sludge is still large.

CHAPTER 3 SLUDGE THICKENING - Marmara

Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is achieved.

Introduction to sludge thickening. A number of processes act purely to remove water from the sludge to reduce its volume. As a result, the suspended solids concentration of the sludge is increased, i.e. the sludge becomes consolidated. These processes are referred to as either thickening or dewatering, depending on the amount of water removed.
