Multi Disc Screw Press

Multi Disc Screw Press Sludge Dewatering Machine, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. Using screw shaft and moving rings to clean itself as clog-free structure, and controlled by the PLC automatically. It's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

Working Principle

Multi Disc Screw Press Layers of spacers, fixed and free rings are secured in place by rods. The sludge dewatering machine inner diameter of the free rings are slightly smaller than the screw major diameter, laying on the screw crest & continuously moving up and down following the screw Press rotation, & creating multi disc screw press a self cleaning effect. The pitch & the zone in between becomes smaller towards the end plate, which gives pressure to dewater the sludge.

Multi Disc Screw Press are perfect for the dewatering of municipal and industrial sludge. We offer these devices in single, double and triple screw versions, with a diameter of 170 to 520 millimeters and a throughput of up to 40 m3 / h. The devices are delivered as a package with an automatic polyelectrolyte station and a dynamic flocculator. The main advantage of the multi-disc screw press is affordable operating costs related to low energy consumption, low consumption of reagents and practically negligible water demand. The device is also recommended for dewatering sludge, which contains a high dry matter content, so they can also be used in industry. An additional advantage of the product is the structure itself - closed and compact, occupying a small area.
