Screw Press Dehydrator

Screw press dehydrator

QK Screw press dehydrator is applied for thickening and dewatering of sludge in WWTPs, with features of small footprint, lightweight and automatic operation with minimal maintenance. The water content of discharge solids is about 80%, for sludge from STP.

Features of screw press dehydrator

● Simple processing, low investment and more energy-efficient;

● Auto control system, more convenient and accurate operation;

● Unique flocculating chemical, higher dewatering performance;

● Lower running cost;

● Wildly applications in varies industry and sewage treatment plant.

How it works?

Sludge feed to filter cartridge from inlet, then moves forward under pushing force between spiral blade and moving rings. As the decreasing of space in each ring, the pressure goes higher, and then filtration goes down by gravity, solids part screw up then discharge from outlet.
