Demineralization Plant

NA Demineralization Plant is set up to remove all sorts of dissolved minerals: cations of calcium, sodium, iron, etcetera, and anions of sulfate, nitrate, and chloride from water to receive 100% purified drinking water.


Mineral salts from water are removed through ion exchange, deionization, distillation, membrane filtration or electrodialysis. A demineralized water plant produces mineral free water by operating on principles like- degasification, polishing and ion exchange. The process starts with the raw water being passed through two of the polystyrene bead-filled beds that comprise the ion exchange resins. The cations exchanges with hydrogen ions in the first bed and the anions with the hydroxyl ions in the second. During this process, the impure ions are consumed by the resins and replaced by pure ones released from the ion-exchange resin. Hydrogen or other positively charged ions are released by cation exchanged resins to replace impure cations and similarly, hydroxyl and other negative ions are released by anion exchange resins to replace impure anions. After removal of ionic contaminants, highly purified water is obtained. The resin needs to be periodically regenerated so that its original ionic form is maintained.

The demineralization plants are rust-free, durable, economical, user-friendly and require low maintenance. It consumes less power and the multiport valves are top and side mounted with high pressure rated PVC pipes. These plants are extensively applicable in the field of steam, power, cooling, such as textiles, breweries, boilers feeding water, ion exchange plants, automobiles, potable water, and hospitals. It is also used in manual or automatic plants as softeners, de-gasifiers, ‘cation’ polisher, mix bed demineralizer, oil and gas sector and pharmaceutical industries.
