Abstract: Disclosed is a process that uses reverse osmosis (RO) or nanofiltration (NF) membranes and ion exchange (IX) water softening resins to maximize the production of drinking water, purified industrial service water or recycled purified municipal or industrial effluents. The membrane and ion exchange units are configured in a manner that enables operation of the system at high permeate recoveries in the range 90% to 99%, thus producing purified drinking water with a minimum volume of wastewater to drains and a very low membrane cleaning or membrane replacement frequency. The process mitigates membrane fouling and scale formation and minimizes the use of water treatment chemicals including acidic and alkali solutions and sodium chloride salt that is normally required to regenerate the IX resin.

Abstract: The invention covers the combination of utilizing the selectivity of an adsorbent to remove species from a liquid containing mixtures of ions and then subjecting the loaded resin to a chromatographic displacement utilizing the most selectively adsorbed species to displace the undesired co-adsorbing impurities. The technique can be used even when the most selectively adsorbed species is present as a minor constituent in the feed solution.
