Ion exchange is an effective, versatile means of conditioning boiler feedwater. The term “ion exchange` describes the process : as water flows through a bed of ion exchange material, undesirable ions are removed and replaced with less objectionable ones. For example, in softening processes, calcium and magnesium ions(hardness) are exchanged for sodium ions. In dealkalization, the ions contributing to alkalinity(carbonate, bicarbonate, etc.) are removed and replaced with chloride ions.
