High U Trough Shaftless Screw Conveyor For Sludge Treatment
Introduction
Dewatered residuals from environmental processes including water and wastewater treatment are ideal applications for KWS Shaftless Screw Conveyors. Wet and sticky bulk materials such as dewatered biosolids, grit and screenings are efficiently conveyed with a shaftless spiral, eliminating the need for internal bearings or a center pipe. Conveying efficiency is improved where elevation changes are required because the shaftless spiral allows for higher trough loading. The perfect solution to efficiently and reliably convey dewatered residuals are KWS Shaftless Screw Conveyors.
