Suitable for the following markets
The Scraper Bridge spans one or several side by side installed longitudinal tanks. The scraper blades push the grit settled in a trough against the flow direction into a sand hopper on the tank bottom. Whilst the suction scraper conveys the sediment from the tank bottom directly into a laterally installed collection trough by means of a submersible or air-lift pump. Floating substances are generally moved in flow direction to the outlet end of the grit chamber and discharged via a ramp or by means of a weir penstock into a scum collection hopper.
