The Multi-Disk Screw press (MDS) is a sludge dewateing machine of solid-liquid separator, which Screw Press Type can realize the Sludge dewatering or Sludge Dehydrator effect. The wastewater sludge is thickened and dewatered progressively along with Screw Press sludge dewatering the movement of the free rings, and ending by the rotary filter Screw Press plate.

The sludge dewatering equipment special tungsten carbide coating of the inner screw and the sludge dewatering system slow rotation eliminates the friction effect and assure the dewatering screw a long life span of the parts. The Sewage Treatment sludge dewatering machine system of filtrate is drained from the gaps between the rings, which differs from the sludge thickening and the sludge dewatering zones. The sludge cake is discharged at the end plate, achieving a minimum solid content of 20%.

The MDS Screw Press dehydrator make it a self cleaning unit due to the friction free movement between the rings, applicable for a wide range of sludge concentration (2000 mg/L – 50000 mg/L)
