Primary sludge

The dry substance content had increased due to a certain process at a waste water treatment plant. Since then, faults had occurred at several points in the pump due to solids accumulating and blocking the pumps. The blockages were causing frequent damage.

After successfully conducting different tests, they opted for the Boerger Multicrusher for dealing with the primary sludge. The Multicrusher was installed on the suction side of the two primary sludge pumps which transfer the sludge alternately.

Operating safely chopping performance and the reasonable wear parts were decisive in convincing the waste water treatment operator. Since the Multicrusher was installed, the primary sludge pumps have been running smoothly.
