The Volute Screw Press Sludge Dewatering Machine is an advanced technology in Sludge Dewatering System that can be a better alternative to traditional filter press like belt press and frame press.
It is clog-free and can reduce the need for sedimentation tanks and sludge thickener, hence saving the overall cost of sewage plant construction.
Working principles :
The wastewater is pushed into the dewatering machine and the sludge will be pressed into sludge cake under the pressure of helical axis blades. As the gap among the helical blades becomes narrower, the filtrate water will come out from the space between the fixed and moving plates.
