Ion exchange definition

Ion exchange means the process of using ion exchange materials such as resin or zeolites to remove undesirable ions from water and substituting acceptable ions, for example, ion exchange for nitrate removal or ion exchange for softening.

Ion exchange means the process pertaining to demineralization of water by ion exchange units that use acids, bases, or salts to regenerate the exchange resins. The hydrogen-ion exchangers have cation-exchange resins that can be regenerated with sulfuric or hydrochloric acid. The hydroxide-ion exchangers have anion resins that can be regenerated with sodium hydroxide (NaOH), sodium carbonate (Na2CO3), or ammonia (NH3). In the case of a sodium cycle ion exchange unit, the zeolite media softener is regenerated with high concentration of sodium chloride (brine). In case of hydrogen-ion and hydroxyl-ion exchangers, the regeneration wastes are neutralized, pH adjusted, and discharged. For sodium cycle ion-exchange units, the regeneration wastewater and the first flush of rinse water contains TDS and chloride concentration of concern.
