A Demineralization (DM) Water Treatment Plant is a system designed to remove mineral salts and impurities from water using the process of ion exchange. It is commonly used in industries where high-purity water is essential, such as in power plants, pharmaceuticals, electronics manufacturing, and chemical processing.

Working Principle

Demineralization works on the ion exchange principle, where cation and anion exchange resins are used to remove dissolved salts.

  1. Cation Exchange Column:

    • Replaces positive ions (e.g., Ca²⁺, Mg²⁺, Na⁺) in water with H⁺ (hydrogen) ions.

    • Water becomes acidic after this stage.

  2. Anion Exchange Column:

    • Replaces negative ions (e.g., Cl⁻, SO₄²⁻, NO₃⁻) with OH⁻ (hydroxide) ions.

    • H⁺ + OH⁻ combine to form pure water (H₂O).
