Demineralisation (DM) Plants
High purity water solutions. Complete mineral and TDS removal for high pressure utilities and sensitive process demands.
High Purity Water and TDS Challenges
High dissolved solids (TDS) and mineral content are critical issues for South Gujarat industries — particularly in highly concentrated industrial zones like Ankleshwar, Jhagadia, Dahej, and Vapi where groundwater mineral content is exceptionally high.
For high pressure utilities and sensitive manufacturing processes, near-zero TDS water is a necessity. Hydrocare Engineers designs, supplies, installs, and commissions high-performance Demineralisation (DM) plants loaded with genuine Tulsion® ion exchange resins to deliver the ultra-pure water required for your operations.
Demineralisation (DM) Plants
How It Works
Two-bed demineralisation plants utilize a strong acid cation exchange resin (H+ form) to remove all metal cations, converting salts to corresponding mineral acids. Water then passes through a base anion exchange resin (OH- form) to adsorb those mineral acids, leaving completely demineralised pure water. Mixed Bed (MB) polishing systems mix both resins in a single vessel to polish water to near-theoretical purity.
