Multi Disc Screw Press

Multi Disc Screw Press also be called screw press sludge dewatering machine,multi disc screw press, multi-disk screw press sludge dehydrator, it is an innovative solution for solid-liquid separation, specifically designed for sludge thickening and dewatering applications. This advanced technology effectively solved a range of common technical challenges encountered in sewage desliming processes, including frequent clogging, difficulty in handling low concentrations, excessive energy consumption, and intricate operational procedures.

Multi Disc Screw Press Sludge Dewatering

Sludge enters the flocculation tank, where polymer addition promotes solid–liquid separation. The thickened sludge moves into the dewatering zone where the screw gradually narrows the pitch, increasing pressure and squeezing out water through moving and fixed rings. The filtrate exits through the gaps, and the dry sludge cake is discharged at the end plate.

Screw press sludge dewatering combines thickening and dewatering in a single compact unit. The system operates through a moving screw and fixed/moving ring mechanism, creating progressive compression and continuous self-cleaning — ensuring clog-free, stable operation.
