A Mixed Bed (MB) Ion Exchange System is an advanced water purification technology that combines cation and anion exchange resins in a single vessel to achieve ultra-pure water. This system is widely used in applications requiring high-quality demineralized water, such as power plants, pharmaceuticals, laboratories, and electronics manufacturing.

The MB process works by utilizing ion exchange resins that remove dissolved salts, minerals, and impurities from water. Unlike separate cation and anion exchange units, a mixed bed system enhances water purity by allowing cation and anion resins to work simultaneously in a single unit, ensuring maximum ion removal efficiency.

How Mixed Bed Ion Exchange Works

1. Pre-Treatment:

   • Raw water undergoes pre-filtration to remove sediments, organic matter, and chlorine, which can degrade ion exchange resins.

2. Cation & Anion Exchange Process:

   • Water enters the mixed bed vessel, where the cation resin removes positively charged ions (e.g., calcium, magnesium, sodium) by exchanging them for hydrogen (H⁺) ions.
   • Simultaneously, the anion resin removes negatively charged ions (e.g., chloride, sulfate, nitrate) by exchanging them for hydroxide (OH⁻) ions.
   • The exchanged H⁺ and OH⁻ ions combine to form pure water (H₂O).

3. Final Filtration:

   • After ion exchange, the purified water undergoes post-filtration to remove any residual impurities and ensure high purity.

4. Resin Regeneration:

   • Over time, the resins become saturated with exchanged ions. The MB system requires periodic regeneration, which is typically done by separating the resins and treating them with acid (for cation resins) and caustic (for anion resins).
