Dewatering: Filtration & Separation

Dewatering is the removal of water from solid material or soil often by centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.

Filtration is a separation technique that often uses a porous medium that retains the solid substance but allows the fluid to penetrate through it. 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 costs for subsequent storage, processing, transfer, end use, or disposal.
