Practical recommendations
Odour problems (2)
The following measures can reduce the occurrence of odours:
-
Reduction of the pump pressure at the vehicle (resulting in a lower flushing pressure)
-
Choosing the appropriate cleaning nozzle (large jet angles, low number of nozzle inserts)
-
Reduction of the pullback velocity of the nozzle
-
Cleaning of preferably short sections from manhole to manhole
-
Regular removal of waste material within a section
-
Improvement of the aeration (air inlet and outlet), e.g. open manholes.
