Product Description
Slurry Treatment System and Screw Press Separator Equipment Water Sludge Separator
Multi-disc Screw Press Dehydrator which uses the screw extrusion principle is a new type of solid-liquid separation device. It reaches the goal of extrusion dewatering sludge by powerful extrusion pressure of changing the screw diameter and distance, and the tiny spacing between moveable annular plates and fixed annular plates.
The core component of Multi-disc screw press dehydrator is the screw body, screw body has configuration with screw surrounded by filtering devices which have moving rings and fixed rings combined together and lined up.
As screw rotates, screw filters and dehydrates sludge while it is conveying sludge. Moving ring of the filtering device is moved upward as screw rotates and water was discharged from the gap made between the moving ring and fixed ring, so that sludge is filtered and dehydrated.The space between the screw and filtering device configured by fixed ring and moving ring becomes narrower as it comes nearer to outlet. Pressure which squeeze sludge become bigger as the sludge moves toward to the outlet, so that the sludge is filtered and dehydrated tightly.
This type of dehydrator doesn’t need cleaning since moving ring in the filtering device is always being moved by the rotating screws and clogging never happen. Therefore, in some wastewater treatment plants, waste sludge pulled out from aeration tank can be dehydrated directly without condensation. Polymer flocculation is used in conditioning before the dehydration.
