Overview of the cleaning methods
Surge flushing
Wastewater volume activated flushing system
Flushing using a flushing chamber
Vacuum operated flushing chamber (2)
The cleaning effect of this method depends on the capacity of the flushing chamber and the specific local conditions, e.g:
- the slope of sewer,
- hydraulic roughness of sewer,
- geometry of the section to be flushed (geometry of the lines/basins),
- exit velocity of the surge wave,
- type of deposit, etc.
The chart shows empirically determined values for the required specific capacities of the flushing chamber and different filling heights [Loren1998]
