A Dewatering Decanter Centrifuge for the Management of Wastewater, Sewage Sludge, and Industrial Liquid and Solids Separation. In 1987, Centrisys designed and built its first centrifuge around what was learned in the field by servicing competitor's equipment in both municipal and industrial applications.

Digested primary sludge + WAS = 25 - 30% total solids. Extended aeration WAS = 18 - 22% total solids. This means that a centrifuge can be used for dewatering and thickening of the sludge. The typical solids loading rate on a centrifuge is 4,000 - 7,000 mg/L with a hydraulic loading rate of 75 - 100 gpm of WAS.

Centrifugal thickening and dewatering of sewage sludge is a high speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid to produce a non-liquid material referred to as "cake.". Dewatering wastewater solids reduces the volume of residuals, improves operation, and reduces …

A centrifuge relies on centrifugal force - the same that a spinning top uses to stay upright - to separate materials by their densities. Centrifuges are used for many applications from the manufacturing of pharmaceuticals to separating cream from milk along with many other industrial uses including sludge dewatering.

With dewatering, the water content is further reduced and the solids content is increased up to 18-20%. Sludge drying, which is the final step, aims to further reduce the water content (< 10%). When thermal drying is used, the sludge is exposed to high temperatures; thus, there is a high energy requirement.
