Multi screw disk press - Sludge Dewatering Machine

Manufacturer Exporter of Clog-free operation, it can reduce the sedimentation tank or sludge thickening tank ultimately saving the cost of the STP ETP project.

Sludge Dewatering Machine - Using screw and the 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, centrifuges, 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 offered by Richa Environmental.

  • Flow Control Tank Feeds a fixed amount of sludge to the flocculation tank whilst the excess sludge returns to the storage tank. Flocculation Tank A Polymer is mixed with the sludge to form flocks suitable for the Volute.


  • Thickening Zone in cylinder unit the sludge discharged whilst the thickened sludge is pushed towards the dewatering zone by the screw.


  • Dewatering Zone: In the section the gap between the rings and the screw pitch decreases gradually in the direction of the end plate, whilst the pressure of the filter element increases due to the volume.


  • End Plate: The end plate creates further pressure from the outlet side so that the sludge becomes drier resulting in an up to 35% solid sludge cakes which is released from the sludge cake outlet.
