ABSTRACT:
Water to be purified is passed through a reverse osmosis step to produce a pure water stream and a waste water stream. The waste water is directed to a deionization step to produce purified deionized water which is recycled to the reverse osmosis step. The process directs far less water to waste as compared to conventional reverse osmosis processes. The process also produces water of higher organic and inorganic purity than can be obtained by either reverse osmosis or deionization alone.
