The process of demineralization is the process of removing mineral ions from a solution, especially water. It results in water that has little or no mineral content and/or dissolved salts. Demineralization can be achieved using a variety of methods such as ion-exchange resins, boiling, distillation, or combinations thereof.
Demineralization is a method of water treatment under which the mineral salts like calcium and magnesium are removed from the water. This type of water is also referred to as DI water in the industry. The deionizing process includes demineralization and ion exchange plant. Demineralized water has a high pH value, low total dissolved solids, fewer mineral salts like calcium and magnesium, and better taste. The process also helps in the reduction of nitrate, arsenic, hydrogen sulfide, etc.
