Demineralization is a type of water purification typically performed using an ion exchange (IX) process to remove nearly all ionic mineral contaminants. Demineralization is often referred to as deionization.
IX demineralization uses cation and anion exchange resins, either in separate or shared columns (mixed bed). After demineralization, the treated water will have a high purity level comparable to distilled water, but usually at a much lower cost.
