Cleaning of pressure lines
NA-06 - Cleaning: Cleaning Pressure Pipes
Physical methods
Physical methods aim at an increase of the sewage flow velocity for cleaning purposes by the addition of pressurised air.
Flushing is performed two to four times a day, or more often if required, by blowing air into the pressure pipe system. Thus, the flow cross section in the pressure pipelines is decreased. Due to the increased sewage velocity, deposits are stirred up and transported further downstream.
