Description
Screw Type Dehydrator Press Machine
Sludge dewatering machine technology is very well suited for municipal wastewater plants etc. the Multi-plate Screw Press uses the Vertical Fibre Cloth Media Filter. Compared to traditional filters this technology consumes a low amount of energy it has a high filtration speed high capacity good effluent quality and a low operating cost. The machine only takes up a small space and can be applied for different types of waste water. It can be applied for the advanced treatment and upgrade of municipal sewage treatment rural and small town sewage treatment advanced treatment or reuse of industrial waste water pre-treatment of raw water purification of surface water pre-treatment.
- No secondary pollution
- The screw shaft rotational speed about 2~3r/min, no vibration and noise is very small .
- Only need a small amount of water for self-cleaning, no secondary water pollution.
- Sludge runs at a slow operating condition. The smell does not spread.

Working Principle
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity;
Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce;
Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.
