Sludge

An environmental service provider uses a Börger Rotorrake for macerating solids in front of a chamber filter press. Sludge from grit chambers, pump chambers and rain overflow basins are supplied in the coarse sludge receiving station of the environmental service provider. In the process, the solids-laden sludge pass a screen with a grid size of 100 mm and are collected in a receiving basin. The connected Rotorrake macerates the solids still left so that they cannot damage the chamber filter press. The Rotorrake is equipped with an automatic reversing control unit which prevents the solids from stucking.
