Abstract

An apparatus for treatment of water for consumption comprises a main storage tank, a pump, a treatment reactor and a valve for controlling the flow of water from the inlet pump to the treatment reactor and from the reactor to a flush discharge and to a waste water discharge. The tank is basically cylindrical with two part cylindrical recesses parallel to the axis of the tank and lying along one side of the tank. Each recess receives a respective one of the cylindrical pump body and the cylindrical reactor body. The pump and reactor are therefore efficiently stored within the cylindrical surface of the main tank. The valve provides five positions including a central closed position, two flush positions and two processing positions. These five positions are arranged by axial movement of a valve member along a cylindrical bore of the valve body. The processing positions are arranged at extreme ends of the stroke of the valve member so that the valve member passes through both flush positions before reaching the opposite processing position. The valve body has openings associated with each port and the valve member has annular recesses for providing communication between the various ports together with a longitudinal channel which communicates between others of the ports to provide the above five positions.
