It depicts the flow of water and solids through various treatment units including clarifiers, anoxic and oxic basins, tertiary filters, ultraviolet disinfection, and a bi solids handling system. The bi solids handling system includes centrifuges, conveyors, and polymer makeup units. A bid option is shown to replace existing centrifuge and solids handling equipment. Key valves, mixers and filters are also identified.
