Flushing shield for large sewers
The HydroGuard Mini flushing shield can be used for eliminating sediment in long and medium size sewer sections (DN600 – DN2000).
The load by pollutants through stormwater discharge can be reduced by its use, and at the same time, it ensures a more consistent load to the wastewater treatment plant. Also, the lifespan of sewers is increased, the odours are eliminated, and costly mobile mode of sewer cleaning is avoided. The flushing is kept constant even during dry weather, in this way it prevents the settling of silt in a proactive manner. The cleaning is accomplished by the energy of the sudden water level drop of water impounded behind the flushing shield (extraction wave).
The frequency of flushing and quantity of flushing water can be adjusted at the equipment. A number of HydroGuard Mini equipment may be used connected in series in very long sewer runs (5-6 km). Upon specific request it is possible to create larger equipment too for sizes exceeding DN2000.
