Abstract
An electrodeionization-based process for purifying water to remove ionic species is disclosed. Ionic removal is accomplished by supplying an electrical current between an anode and a cathode of an electrodeionization module in the range of about 1.5 to 15 times a “theoretical minimum current”. The current is supplied by a power source capable of automatically increasing or decreasing voltage in response to a change in the electrical impedance of the electrodeionization module to maintain constant current. Conduct of the process on pretreated water yields deionized water of good quality, while maintaining conditions that promote the longevity of the electrodeionization module.
