Cassava, Vinasse, Coconut Palm Oil Sludge Filter Screw Press Dewatering Machine For Oily Waste Treatment

Product Application

Our company are always focusing on independent technology innovation of themselves. we have successfully developed the new generation of sludge dewatering technology - multi-plate screw press, a screw type sludge dehydrator that is much more advanced in very aspects than belt presses, centrifues, plate-and-frame filter presses, etc. It features clogging-free, wide range of applications, low energy consumption, simple operation & maintenance.

Industrial waste dewatering equipment compact screw type filter press

Main Parts: Sludge concentration & dewatering Body; Flocculation & Conditioning Tank; Integrate Automatic Control Cabinet; Filtrate Collection Tank

Working Principle:

Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path

It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc

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.

Product Feature:
Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L
The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L.


Since MSP can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.
