Sludge dewatering press is treatment which generates dewatered cake with high dry solid content and a quality of cent rate water, leading to vital sludge volume reduction. So, that's why the prices which are related to sludge dewatering screw press have been decreased.
Multidisc are arranged one after other with alternate disc being moving and fixed.The gap between the plates acts as media for fine filtration.The screw press main unit requires very very low power motor and the filtration surface area consists of a multiple discs which are self-cleaning, and generally do not clog, thus, the sludge press can be used continuously.
The main unit of the sludge dewatering screw press is of multi-shaft design. Hence,when two or more main units are configured into one machine, any individual shaft can be repaired or serviced without interrupting operations.
Sludge Dehydrator Process
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.

Sludge Dehydrator Application
Low Power Consumption
Simple and short start-up and shut
Continuous operation. Hence continuous output can be obtained
Process can be automized
Only electricity and water supply for cleaning is required, and that too in less amount
For a multi-channel machine, one or more channels may be removed for maintenance purposes, while the machine with the remaining channels may still be operated
No clogging. Cleaning is automized and is easy
Long life of discs
No external lubrication system is required
