Process data
Measuring task:
Point level detection
Measuring point:
Tank
Measuring range up to:
0.5 … 1 m
Medium:
Sludge/wastewater
Process temperature:
+20 ... +40 °C
Process pressure:
0 … 0 bar
Special challenges:
Abrasion, buildup
Application
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.
