Method for sanitizing an electrodeionization device

A method of sanitizing an electrodeionization (EDI) device associated with a deionized water producing system, the method comprising:

• providing a water purification system configured for producing deionized water, the water purification system comprising at least one of a micro-filtration apparatus, an activated carbon tower, or a reverse osmosis apparatus;
• providing an EDI device, integrated with the water purification system, wherein the EDI device comprises an internal chamber comprising:
• an anode compartment adjacent a first end of the internal chamber, a cathode compartment adjacent an opposite second end of the internal chamber, and a plurality of ionic membranes positioned between the anode and the cathode compartments;
• modulating an isolation valve to stop a fluid supply to the internal chamber;
• supplying an electrical power to the internal chamber to create a temperature rise with the internal chamber;
• determining whether a temperature within the internal chamber is within a sanitization range;
• and
• maintaining the temperature within the sanitization range;
• wherein the electrical power sanitizes the EDI device while the fluid supply to the internal chamber is substantially reduced.
