Sludge Dehydrator Description
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.
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 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 Widely Use
Applicable sludge concentration of 2000mg/L-50000mg/L.
Most especially for the oily sludge.
Fully Automatic Control
Combining with the auto control system, the machine runs very safely and simply and can be programmed according to the requirement of the users. It can operate automatically for 24 hours, unmanned.
Sludge Dehydrator Features
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.
Sludge Dehydrator Application
All range of industries ETP & STP
Faecal Sludge management
Primary sludge and biological sludge dewatering
Wastewater treatment plants – New / Existing
