What is the Sludge Thickening Process in Water Treatment

Mar 06, 2018Sludge thickening is important because it is the process used in wastewater treatment centers to increase the solids concentration and decrease the free water. This step minimizes the load on the downstream processes, such as sludge dewatering and digestion.

Centrifuge Thickening and Dewatering Biosolids US EPA

Centrifuges have been used in wastewater treatment since the 1930s. Thickening before digestion or dewatering reduces the tankage needed for digestion and storage by removing water. Dewatering removes more water and produces a drier material referred to as “cake” which varies in consistency from that of custard to moist soil.
