HLDS Multi-plate Sludge Dewatering Screw Press belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. HLDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.Main Features ♦ Exclusive pre-thickening device enables a wide solid concentration ranging from 3000mg/l~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 maintenanceAdvantages Widely UseApplicable 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 CostPower-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.Non-clogging Self-cleaning with small amount of water.Suit for Oily SludgeNo secondary pollutionThe 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
