Abstract
A reverse osmosis apparatus includes a pump for pressurizing feed water introduced into a pressure resistant container in which is slidably mounted a semipermeable membrane cartridge. A rod, attached to an end of the semipermeable membrane cartridge, passes slidably and sealingly through one end of the pressure resistant container and is connected to means for reciprocal actuation. Means, preferably common, are provided to actuate the pump and the rod which imparts longitudinal reciprocal motion to the rod and the membrane cartridge within the pressure resistant container, thereby providing improved turbulence and circulation of the feed water through the semipermeable membrane cartridge over the membrane surfaces. The common means may be in the form of a lever operated by a handle or pedal, or by a power source such as an electric motor.
