Sludge dewatering

Point Level
Sludge dewatering

Overview

The digested sludge is dewatered prior to drying in centrifuges or filter presses. The sludge liquor thus obtained passes through the cleaning process of the WWTP once again. A level detector controls the pumps in the filter water tank to prevent overfilling. The discharge of the dewatered sludge is controlled by a point level sensor.
