Working Principle

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 moving and fixed rings. The movement of the moving rings and the 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.

Spiral sludge dewatering machine Advantage

1. One-in-all design, fits in small facility

Multi-Disk Screw Press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to other methods, and the sludge is instantly thickened by gravity. For this reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can be directly fed without pre-thickening.

2. Easy operation/Easy maintenance

Full automatic 24-hour operation without an operator on-site is possible with automatic operation control using various sensors. With this function, manual operation, such as starting or stopping, is not required. Moreover, daily maintenance is minimized, requires no skilled labor neither special knowledge, so that everybody can use it easily.

3. Power and water saving

Multi-Disk sludge dewatering machine prevents filter mesh from clogging with its unique self-cleaning mechanism, removing the need for huge amounts of water for clogging prevention. When compared with dewatering equipment of the same throughput, the amount of cleaning water required for Multi-Disk Screw Press is about 1/115th of belt press and about 1/12th of conventional screw press.
