Pure & Reliable Water Treatment
A Demineralization (DM) Plant is a proven water treatment system designed to remove dissolved salts, minerals, and impurities through ion exchange technology. DM plants produce high-purity water that is essential for applications requiring low conductivity and mineral-free water, such as boilers, pharmaceuticals, laboratories, and power plants.
Ralsonics offers custom-engineered DM Plants with advanced ion-exchange resins, robust construction, and user-friendly operation, ensuring consistent and reliable performance.

A typical DM plant operates using ion exchange resins that replace dissolved ions with hydrogen (H⁺) and hydroxide (OH⁻) ions, which then combine to form pure water. The process involves:

RO plants use membranes to remove salts, while DM plants use ion exchange resins. RO is ideal for high TDS feed water, while DM is best for low to medium TDS water.
Regeneration frequency depends on feed water quality and plant capacity but typically occurs after 8–12 hours of operation.
Resins generally last 3–5 years with proper regeneration and maintenance.
