Screw Press Sludge Dewatering Dehydrator for Wwtp

Screw Press Sludge Dewatering Machine, as a new type of dewatering equipment, widely used for different industries wastewater treatment,especially for oily sludge.


1.    24 hours automatic running
24 hours automatic running just prepare enough polymer without man around.

2.    Small footprint
Saving space makes installing easier and reducing construction cost.

3.    Cost Saving
1/60 Water Consumption of Belt Filter Press, 1/15 Electric Consumption of Centrifuge

 

Working principle
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down continuously. Most water is pressed out during the thickening zone and falls down to the filtrate tank. At the same time, sludge is thickened.
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, and under the pressure of back pressure plate, the pressure in the filter chamber increases higher and higher, the sludge is greatly pressed and dryer sludge cakes are produced.
