The Sludge Dewatering Screw Press Machine for Wastewater Treatment developed by HOLLY utilizes the dewatering principles of force-water homo-direction, thin-layer dewatering, proper pressure and extension of the sludge dewatering path. The new equipment, more advanced than the traditional dewatering equipment which are easily blocked, unsuitable for low-concentrated sludge and oily sludge, of high consumption and difficult to operate, well eliminate these problems and are of higher efficiency and power saving.

Main Features

♦ Exclusive pre-thickening device enables a wide solid concentration ranging from 3000mg/l to 50000mg/l
♦ Fixed and moving plates replace filter cloth, self-cleaning, clog-free, easy to handle oily sludge
♦ Low running speed, low noise, low power consumption, 1 /8 of Belt Press and 1 /20 of centrifuge
♦ Less capital construction cost, more excellent working performance
♦ Fully automatic control, Easy operation and simple maintenance

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.

Low Running Cost
Power-use: less than 5% of centrifuge. 
Water-use: less than 0.1% of belt filter press. Polymer: saving around 60%. 
Room: saving more than 60% of the investment for dehydration room.
Self-cleaning with small amount of water.
Suit for Oily Sludge 

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.
