ABSTRACT OF THE DISCLOSURE Reverse osmosis, particularly for water desal- ination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. Pump action is assisted by returning pressurized concentrate fluid acting on reverse side of the pump piston or dia- phragm. Directional valves controlling alternating admis- sion and venting of concentrate fluid to and from pump cylinder are actuated mechanically by reversal of force applied to the piston rod. Mechanical dwell is provided in the piston or diaphragm motion during directional valve actuation. Pump may be operated by a manual lever or by a crank mechanism on a low speed rotary shaft. An optional differential surge absorber provides continuity of feed solution circulation past membrane surfaces during the return pump stroke, thus minimizing detrimental salt concen- tration build-up on the membranes.
