De Mineralization System

A demineralization plant removes dissolved mineral salts and ionic contaminants from water using an ion exchange process. It works in two stages. The Strong Acid Cation unit removes positively charged ions like calcium and magnesium. The Strong Base Anion unit then removes negatively charged ions like chlorides and sulphates. The result is highly purified water with TDS below 10 PPM. H2OMSPL's demineralization plants are built for industrial and pharmaceutical use, operate at 2.5 to 3.5 bar pressure, and are available in capacities from 500 LPH to 10,000 LPH.

More industries than you might expect depend on demineralized water. Pharmaceutical manufacturers need it to meet product purity and compliance standards. Power plants use it for boiler feed water to prevent scaling and equipment damage. Chemical processors, electronics manufacturers, textile units, and food and beverage producers all face problems when mineral contamination enters their processes. H2OMSPL's industrial demineralized water systems are built for these demanding environments and are available in multiple vessel materials, including FRP, SS 304, and SS 316 to suit different facility requirements.

A water softener only removes hardness-causing minerals like calcium and magnesium, replacing them with sodium ions. Dissolved salts and other contaminants remain in the water. A water demineralization plant goes much further, removing nearly all dissolved ionic matter and bringing TDS down below 10 PPM. That level of purity is essential for pharmaceutical production, steam generation, and laboratory applications where even trace mineral contamination causes failures. H2OMSPL also recommends adding a sand filter and carbon filter before the DM plant to protect the resin and extend system life.

Over time, the ion exchange resin inside a DM plant gets saturated and loses its ability to remove contaminants. When that happens, regeneration is needed. The Strong Acid Cation resin is restored using hydrochloric acid, while the Strong Base Anion resin is regenerated using sodium hydroxide. H2OMSPL's systems include dedicated Acid Measuring Tanks and Caustic Dilution Tanks to make this process safe and manageable on-site. Another practical advantage is that feed water can be used directly for rinsing after regeneration, which reduces water wastage and keeps operating costs under control.

Start with your feed water quality. Knowing your TDS levels, hardness, and ionic composition determines the right resin configuration and system size for your needs. H2OMSPL offers standard models from 500 LPH to 10,000 LPH, with custom builds available for larger or more specific requirements. Vessel material selection also matters, with options including FRP, SS 304, and SS 316 to suit different process environments. Adding a sand filter and carbon filter upstream as pre-treatment protects the DM plant from fouling. A built-in conductivity indicator lets you monitor output water quality in real time.
