ABSTRACT:
A method for purifying water, comprising separating a supply stream into a permeate stream and a reject stream, removing non-monovalent salt impurities from the reject stream to produce a treated stream; providing the treated stream to a concentrating compartment of an electrodeionization unit; and, producing an EDI product stream of purified water.
