Demineralization is a method of purifying water. While the term demineralization can refer to any treatment technique that removes minerals from water, it is usually reserved for ion exchange (IX) processes that remove ionic mineral pollutants almost completely. The phrases deionization and demineralization are frequently used interchangeably. The Process of removing minerals and salts from water using ion exchange process. Demineralized water mostly contains of Calcium, Magnesium, Sodium, Chloride. The demineralized water is also called deionised water or Demin water. The presence of certain ionic pollutants will determine whether anionic or cationic resins are required. The exchange of ions in a normal IX reaction merely results in the replacement of contaminated ions with less undesirable ions. The goal of an IX sodium softening system, for example, is to replace hardness ions (e.g., Ca2+ or Mg2+) in solution with sodium ions (Na+).As a result, the treated solution will be soft to the touch, with a higher sodium ion concentration. While this is appropriate in many cases, other operations require near-total dissolved solids removal. This is when demineralization enters the picture. Cations in the feed water are exchanged for hydrogen (H+) ions and anions for hydroxyl (OH–) ions during demineralization.
- The process can be used to soften highly acidic or alkaline waters
- The water softened by this process is good for high pressure boilers .
- It produces water of very low hardness (upto 2 ppm ) .
