Pre-Thickening Volute Screw Press Sludge Dehydrator for Wastewater Treatment

DW screw press sludge dewatering machine is a new type of filter press. Its unique mechanical structure makes it have the advantages of small floor area, no blockage, automatic unattended operation, no need of sedimentation tank and sludge thickening tank. Compared with the traditional belt filter pressand plate and frame filter press, the closed design can greatly improve the site environment. The driving motor adopts the gear reducer with low speed and high torque, which has lower energy consumption and noise compared with the centrifuge.The main body of screw filter press is made of multiple fixed plates and moving plates with the screw shaft running through it.The front part is concensed section and the ending part is dewatering section. It can concentrate  and dewater sludge in one chamber.Sludge will be transported to the dewatering part after being concentrated in the dewatering section.In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the block of the back platen .Then the volume decrease continuously,and the purpose of fully dewatering will be achieved.
