Shafted washer compactors for wastewater treatment
Effectively compact and dewater waste streams while reducing volume by up to 65%—an ideal solution for handling organic matter in wastewater treatment systems.

Compacts and Dewaters Wastewater Screenings
The VWP Shafted Washer Compactors from WAMGROUP offer an effective solution for wastewater treatment across municipal and industrial sectors. This robust equipment utilizes a thick steel shafted spiral, driven directly, that rotates within a cylindrical compacting zone. It efficiently dewaters and compacts screenings, while an integrated spray nozzle system removes organic particles, returning them to the purification process. With a capacity ranging from 1.5 to 6 m³/h, it suits various settings such as abattoirs, food processing, and paper pulp treatment. Built from durable 304 L / 316 L stainless steel, with options for ST 52 steel, it ensures longevity and resistance to corrosion. The VWP compactor’s energy-efficient design supports continuous operation, reducing volume by up to 65%, and is low on maintenance, thanks to its simplified engineering. Optional features like different inlet hopper sizes, compacting pipe lengths, and variable motor protection levels allow customization to fit your specific operational needs.
