Abstract
Reverse osmosis, particularly for manually operating water desalination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. The manual pump action is assisted by using two pump pistons to provide a continuous flow of feed solution to the concentrate side of the membrane to continuously flush the membrane surface. The concentration polarization is controlled by exhausting the high pressure concentrate to atmosphere through an orifice and relief valve.
