MULTI DISK SCREW PRESS
Multi disk screw press using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge.
Multi-Disk type screw press consists of a dewatering unit (this is composed of the screw and the filtering part) a mixing/concentrate tank and a body. Filtering part which is accumulated with both moving and fixed rings. Those rings filter the sludge and separate it from the water. The filtered sludge is then moved and pressurized by the rotating-screw.
The sludge is entered into the bottom of the thickener and mixed with the polymer by an impeller. Inside this thickener, the water and the sludge are separated. The separated water is discharged through a device that excludes water. By repeating this process, sludge is continuously concentrated. Finally, the concentrated sludge is injected into the Multi-Disk type Screw press.
