Quatech Screw Press for Sludge Dewatering

Name: Quatech Screw Press
Brand: Quatech

Quatech QSP 15 to QSP 750 screw presses for STP and ETP sludge, from QuaSys Inc.

Quatech Screw Press

Quatech is QuaSys Inc.'s own brand. The Quatech Screw Press is an economical and eco-friendly sludge dewatering machine. It uses screw extrusion to separate solids from liquid, with strong squeezing forces created by variations in screw diameter and pitch and the small gap between the floating and fixed rings.

Typical wastewater plant applications include thickened or un-thickened waste activated sludge (WAS), digested sludge from aerobic or anaerobic processes, and dissolved air flotation (DAF) sludges. It also dewaters liquid sludges from industry and municipal applications. For municipal or bio sludge it typically produces a cake with 20% dry solids. It is a simple, slow-moving device that dewaters by continuous gravitational drainage.

Why QuaSys Inc.?

Correct Sizing: Machine selected from your sludge flow and solids load.
Commissioning Support: Polymer dosing guidance during commissioning to optimise cake dryness from day one.
AMC & Spares: Maintenance contracts and spare parts support across India.
