DM Plants: Working Principle, Process And The Application

DM Water treatment plants use the demineralization process of removing excess minerals and salts from raw water by using an ion-exchange process. Demineralized water is free from all sorts of dissolved minerals and excess salts by using one of these following processes.

The demineralized water, also known as deionized water that means the excess of minerals and ions are removed. Minerals like sodium, calcium, iron, chloride, and sulphates are common ions present in hard water. Deionization or Demineralization of water is a physical process that uses ion exchange resins to replace the mineral salts in water. Because of the majority of impurities and dissolved salts, water becomes hard and needs to be treated before use.

The Doctor Fresh DM plant produces high-quality water that is far better than distilled water in a quick time and also ignores scale buildup. De-mineralization is the proven technology for hard water treatment. DM water plant produces water that is softer by applying the principles of ion exchange and polishing. Demineralized water can be used for various day-to-day practices without any further treatments.

The Working Principle Behind Demineralization Of Water

When the raw water is passed through two small ion exchange resin beds, the cations get exchanged with hydrogen ions in the first bead, and the anions are exchanged with hydroxyl ions in the second bead. Ion exchange is a rapid and reversible process in which excess ions present in the water are replaced by ions released in the ion-exchange resin.

The excess ions are pulled out by the resin, and the rest is restored in the original ionic form. The Positively-charged ions are called cations, mostly metals; negatively charged ions are called anions and are non-metals. Many industries have started using DM plants to get demineralized water for industrial purposes. However, some industries have been using these units for a long time ago to use in-

  • Industries that require water to operate high-pressure boilers
  • Food and beverage industries where need in large quantity
  • Units like electronic goods manufacturing
  • Medicine and other food processing industries

The Reason To Choose Doctor Fresh DM Water Plants

The water free from any mineral is called de- mineralized as various salts are diluted in water. When the water has such a mineral that is no longer required, it must be treated in ion exchange resins to adsorbs the positively charged ion. In which the cations pass through an anion resin column that adsorbs the negatively charged anions, and water becomes free from the excess ions. Our DM water treatment plants are made to be tough and durable that only require basic servicing.

  • The demineralized water is better in quality than distilled water that we use for drinking
  • The DM plants are available for large, medium, and small scale industries
  • The DM water plant never uses any chemicals or do not produce any hazardous byproducts
  • The new age DM plants are compact, and that needs minimum space for installation
  • Using DM plants to demineralize water are one of the cost-effective methods

Frequently asked questions

Demineralization is the process of elimination of mineral salts present in the water by using an ion-exchange process. The demineralization water is entirely free of dissolved minerals due to distillation, deionization, membrane filtration, and others.
