Demineralization is the removal of dissolved minerals that form salts when water is evaporated. These salts have corrosive properties and must be removed for industrial processes for the safety of equipment, such as high-pressure boilers. In ion exchange demineralization applications, salts are replaced with hydrogen and hydroxide to form pure water. However, in demineralization ion exchange systems, ion exchange resins will remove all mineral salts, except for traces of sodium and colloidal (undissolved) silica.
