DM Water Plant

A DM water plant is a specific water treatment plant that removes dissolved salts and minerals from raw water to provide ultra-pure water suitable for industrial use. DM water plants serve critical needs in industries such as pharmaceuticals, power, electronics, and labs—essentially any setting where water quality impacts the quality of the product or the lifespan of the equipment. DM water plants work through a multi-phase ion exchange process with cation exchange resins and anion exchange resins. The plant replaces hardness ions such as calcium and magnesium with hydrogen ions and removes hardness-causing anions, such as chloride and sulphate, with hydroxide ions, making demineralised water with very low conductivity and total dissolved solids (TDS). Today, DM water plants are generally comprised of FRP or stainless steel vessels, automatic multiport valves for backwashing, test taps, inlet and outlet monitoring meters, and a chemical regeneration system utilising an acid (in the cation resin vessel) and alkali (in the anion resin vessel) chemical solution system. High-end systems include a mixed-bed polisher stage for ultra-pure water, programmable logic controller (PLC) automation with reporting, and remote monitoring. DM water plants produce suitable water for boiler feed water, cooling towers, chemical processing, and rinsing. DM water plants have different capacities, from within 500 LPH all the way up to and exceeding 100,000 LPH, suitable for any lab or commercial need.
