Screw press can be widely used in municipal waste water treatment engineering’s as well as the industrial wastewater treatment systems such as petrochemical processing, light industry, chemical fiber, paper-making, pharmacy and leather etc. The multi-plate screw press, as proven by the practical applications, can help to make considerable economic and social benefits for customers.
The conditioned sludge flows into the filter chamber from the flocculation tank and is pushed forward the discharging end. With the gap between the thread of the shaft is getting more and more narrow, the pressure on the sludge is getting higher and higher. Then the water is separated from the sludge and flows out from the gap between the movings and the fixed rings. The movement of the moving rings and he fixed rings cleans the gap between them and prevent the machine from blockage. The filtered sludge cakes are pushed forward by the shaft and finally discharged from the end.
