Abstract

A pipe gallery includes an exterior peripheral wall containing a gallery upper chamber, a backwash waste chamber, and a gallery lower chamber. A gallery influent line and filter influent pipes are connected to the gallery upper chamber. A backwash drain line and secondary pipes are connected to the backwash waste chamber. Filter effluent pipes and a gallery effluent line are connected to the gallery lower chamber. The lower chamber may also include a separate supply chamber, to which a gallery backwash supply line and filter backwash pipes are connected. The filter influent pipes and secondary pipes may be connected to the top chambers of filter cells in a filtration system, while the filter effluent pipes are connected to bottom chambers of the cells. Valves are used to create separate filtering and backwash pathways.
