ABSTRACT:
A multiple purpose tank has an inlet-outlet port, an inlet port and an outlet port connected to a drain. A flexible liquid-proof liner in the tank is connected to the inlet-outlet port to form a variable volume container. Automatic valve means controls the flow of effluent-untreated liquid to the drain and the pressure of effluent-untreated liquid in the tank on the liner and the variable volume container formed thereby. A reverse osmosis module has an inlet port for connection to a pressurized source of untreated liquid and an outlet port connected to the inlet port of the tank. The module has an outlet port connected to the inletoutlet port of the tank to discharge treated liquid to the interior of the tank. A manually actuated control valve controls the flow of effluent-untreated liquid to the tank.
