Sludge Dewatering
Our sludge dewatering technology is based on screw presses.
The fluid, raw sludge is flocculated and pumped into a screw cylinder, where the wall consists of alternating fixed and moving rings and a central screw. As the flocculated sludge passes through the cylinder the water drains out though 0,5mm gap between the rings. The sludge becomes more and more dry as it passes through the cylinder and at the last section the sludge is pressed into a cake and released.
The screw press works using slow-moving, energy saving processes that need a minimum of attention during operation.
The screw press can be directly integrated with our flotation-units.
The capacity is based on the amount of solids and ranges from 10 kg DS/h and up to 300 kg DS/h.
