Screw screens for solids-liquid separation in waste water
Achieve crucial solids-liquid separation with screw screens designed to handle diverse wastewater challenges, enhancing treatment efficiency and reducing sludge handling costs.

Separates and Dewaters Solids from Wastewater
The WASTEMASTER GCP-GCE Screw Screens from WAMGROUP are engineered-to-order solutions for effective solids-liquid separation in wastewater treatment processes. These screw screens combine screening, conveying, and dewatering in a single unit, eliminating the need for internal bearings and reducing maintenance costs. Ideal for municipal, industrial, food processing, and tannery applications, they deliver clarified effluent and de-watered sludge cakes efficiently. With a processing capacity of up to 1,000 m³/h, these units integrate seamlessly into continuous or intermittent operations, featuring a robust design made from 304L/316L stainless steel for corrosion resistance. The shaftless spiral design prevents jamming, ensuring smooth operation even with fibrous materials while allowing for solids volume reduction of up to 35%. The WASTEMASTER GCP variant includes a compacting section for additional sludge dewatering, whereas the GCE-type is tailored for applications where compaction isn’t required. This flexible equipment supports a range of customization options, including alternative screen types, motor protection levels, and angle adjustments, ensuring it meets diverse client needs within various environmental and waste processing industries.
