Screw Press Dewatering Unit

Fully automatic sludge dewatering, stainless steel construction

Data Sheet

A fully automatic sludge dewatering unit made of acid-resistant stainless steel.

Operating principle: the slow movement of the rings, driven by the rotating central screw, moves large sludge agglomerates without breaking their structure, which helps drain the liquid. The dewatered sludge is then conveyed by the screw to the press outlet. At the end of the chamber, a cover allows easy adjustment of the dewatering degree.

Equipment

Dynamic flocculator
Sludge pumps
Polymer pump
Control system

Advantages

10x lower energy consumption compared to a centrifuge press20x lower wash water consumption compared to a belt pressVery low servicing costs
