Sludge Dewatering Centrifuge - Beckart Environmental

A sludge dewatering centrifuge is an excellent investment for municipal and industrial facilities that need an effective means of separating water from sludge. The equipment works by rotating sludge at a high speed and causing the water and solids to separate and then exit opposite ends of the machine.

Cost Effective Biosolids Dewatering – Centrifuge, Belt ...

The material cost of Geotube dewatering units can range from only AU$35 to AU$120 per dry ton of solids depending on size of the units. The larger the unit, the more efficient it is in terms of dewatering volume. In cases where polymer flocculent is introduced as the sludge enters the Geotube the cost will increase a small fraction.
