Multiplate Sludge Dehydrator With Automatic Poly Dosing System

Sludge Dehydrator Description

---

The main purpose of Sludge dewatering machine is to minimize the handling and disposal. Sludge dewatering press is the most cost effective method of dewatering, and hence helps to sustain the environmental objectives of company. 

Sludge dewatering equipment is not intended to treat the sludge or liquid but; it only separates the liquid components & solid components so it will get easier & cost effective to handle the separate phases of the disposal. Once the final sludge has been dewatered, then liquid is treated in ETP/STP & solid sludge is disposed.

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.
