Ion Exchange Treatment Systems

ion exchange water treatment

What is Ion Exchange?

Ion exchange (IX) is a purification method that softens water and removes unwanted minerals and other substances. A reversible process, IX works by removing undesirable metallic salt ions and replacing them with ions attached to a media or resin. Because ions have differing affinities for the resin, IX occurs as the new ions replace ones with less attraction as the water flows over the media or resin. Ion exchange is a form of sorption similar to absorption and adsorption.

There are two types of exchangers: cation exchangers (targeting positively charged ions, or cations) and anion exchangers (targeting negatively charged ions, or anions). Ions most often used as the exchange ions are sodium and chloride, which are used to remove ions attached to hard minerals, nitrate, uranium, radium and other radionuclides. Eventually, the physical resin will be saturated with the undesirable ions. Depending on the application, the resin may be regenerated on site, at a central regeneration facility or be completely replaced and disposed of.
