DM (Demineralization) Plants

A Demineralization (DM) plant removes mineral salts from water using ion exchange. Cation and anion exchange resins swap out minerals for harmless ions, resulting in high-purity water ideal for boilers, electronics, and other applications requiring low mineral content.

Process Description:

In the context of Water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the Water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively-charged ions are called cations and are usually metals; negatively-charged ions are called anions and are usually non-metals).

Target Impurities:

  • Cations
  • Anions

    • Advantages:

  • Heavy metals and sodium content can be removed.
  • Compact in space.
  • Reduces the overall cost of production.
