Volute Sludge Dewatering Screw Press Machine

The volute sludge dewatering screw press machine uses multiple screw moving and static ring to extrude the sludge into the dewatering area while the water is purified by gravity flow.
The screw press machine integrates automatic control cabinet, flocculation and tempering tank, sludge concentration and dehydration body and sump, which can realize high-efficiency flocculation under continuous operation and continuous sludge concentration and The press dewatering work, and finally the collected filtrate is refluxed or discharged.

Features and Advantages
1. One-in-all design, fits in small facility
Volute sludge dewatering screw press machine adopted the unified structure that serves two functions, thickening and dewatering in the single machinery. The secret lies in the self-cleaning mechanism. 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. Wide range of line-up/Small footprint
The model of sludge dewatering machine based on the customer needs can be selected from a wide range of line-up, from a super-small 0.5 kg-DS/h throughput to a large 780 kg-DS/h throughput. Likewise, sludge thickeners can be selected from 1 m3 to 90 m3/h capacity.

3. Easy operation and 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.

4. 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.
