Water Handbook - Ion Exchange & Water Demineralization

For high-pressure boiler feedwater systems and many process systems, nearly complete removal of all ions, including carbon dioxide and silica, is required. Ion exchange systems are used for efficient removal of dissolved ions from water. Ion exchangers exchange one ion for another, hold it temporarily, and then release it to a regenerant solution.
