Abstract
A reverse osmosis system which includes a purified water storage tank, has a by-pass pipe around the concentrate flow control of its membrane module and a normally closed valve in the by-pass pipe. The by-pass pipe valve is opened automatically when purified water is withdrawn from the purified water storage tank, thereby to flush feed water through the membrane module.
