Surge flushing – Practical experience
According to Haußmann, the following principles apply [Haußm1998] [Dohma2002a]:
-
A high frequency of surge waves (interval flushing) prevents the new formation of deposits more effectively than individual heavy surge waves.
-
Prior to flushing, the water level in the downstream water (ponding) should be rather low, so that the surge wave can directly act on the deposits and is not affected by the standing water.
-
In [ATV1995], a minimum filling depth of 4 to 5 cm is recommended, because coarse particles can be mobilized much more easily under buoyancy.
