Demineralization is the process of removing mineral sales from water by using the ion exchange process. Demineralization Water is water completely free (or almost) of dissolved minerals. A Demineralised (DM) Plant is a specialized water purification system designed to remove dissolved salts, minerals, and ionic impurities from water using advanced ion exchange technology, producing ultra-pure water essential for critical industrial and laboratory applications.
By employing a series of cation and anion exchange resins, the DM plant effectively eliminates hardness-causing elements such as calcium, magnesium, sodium, chloride, sulfate, and nitrate ions, resulting in water with very low conductivity and total dissolved solids (TDS). This high-purity water is crucial in industries like power generation, pharmaceuticals, electronics manufacturing, chemical processing, and boiler feed water treatment, where even trace mineral content can affect product quality and operational efficiency.
Demineralized water from a DM plant helps prevent scaling, corrosion, and fouling in sensitive equipment, thereby enhancing performance and extending equipment life. Modern DM plants often feature automated regeneration and monitoring systems to ensure continuous, reliable operation with minimal maintenance. Investing in a demineralised plant guarantees consistent water quality, supports regulatory compliance, and contributes to sustainable industrial processes by optimizing water usage and reducing waste.
● Distillation
● Deionization
● Membrane filtration (reverse osmosis or nano filtration)
● Electrodyalisis or other technologies.
● Demineralization water also known as Deionized Water, Water that has had its mineral ions removed.
● Mineral ions such as cations of sodium, calcium, iron, copper, etc and anions such as chloride, sulphate, nitrate, etc are common ions present in Water. Deionization is a physical process which uses specially manufactured ion exchange resins which provides ion exchange site for the replacement of the mineral salts in water with water forming H+ and OH- ions. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.
Water Pure Filteration is a well known manufacturer of RO Systems in Ahmedabad. Reverse osmosis (RO) is a water purification technology that uses a Semipermeable membrane.
