Screw press

Reducing of sludge volume

  • Simple operation
  • Slow rotating speed resulting in low maintenance
  • Low power requirement


the sludge is fed into the bowl and moves through the inclined conical bowl with the screw rotation. The solid part is dewatered by the moving discs, while the water exits between the disc gaps. Solids loses more water while moving through the bowl, thanks to the pressure generated by the conical shape. The last sector of the bowl generates more muddy water which is collected in a dedicated tank and it can be pumped back to the condensing tank. Pressurized water is sprayed on the drum, automatically at periodic intervals for cleaning purpose. If the load of solids changes, the pressure cone automatically adjusts the compression rate to keep constant the required dryness.
