Sludge Dewatering

Sludge Thickener (Screw/Ring Technology)

Clog-resistant sludge thickener using alternating fixed and moving rings with a central screw conveyor for continuous operation.

The sludge thickener consists of a cylindrical filter element composed of alternating fixed and moving rings, creating narrow gaps for filtrate discharge. A central screw conveys and compresses the sludge along the cylinder. The movement of the rings provides a self-cleaning effect that prevents clogging.

Key advantages include clog-resistant design, low wash water consumption, and stable performance even with oily sludge. It is ideal for continuous sludge thickening in situations with limited installation space and low maintenance requirements.
