We are manufacturing D.M. plants for the process of removing mineral salts from water by using the ion exchange process.
Demineralized 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.
De-mineralization technology is the proven process for treatment of water. ADM Water System produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. Demineralized Water System finds wide application in the field of steam, power, process, and cooling.

Demineralisation plant
Natural water contains a large number of dissolved materials in dilute form, the majority of which are salts. These solids are referred to as TDS. Demineralization, also known as deionization, is the process of removing mineral salts from water via an ion exchange technique. This process, also known as deionization, removes both cations and anions. In other terms, it’s a wastewater treatment procedure.
An ion is an atom or group of atoms carrying an electric charge. Positively charged ions are termed cations and are usually metals,eg- Iron,Calcium ,Magnesium ,Copper,Sodium, Potassium etc. Negatively charged ions are called anions and are usually nonmetals.These include chloride, carbonate, sulphate, bicarbonate, and nitrate etc
High-purity water obtained through the deionization process has no ionic contaminants. As a result, it is widely used in laboratories and enterprises to ensure that their units run well.
Deionization is a physical process that uses specifically designed ion exchange resins to offer an ion exchange site for the replacement of mineral salts in water with water, resulting in H+ and OH- ions. Because dissolved salts make up the bulk of water contaminants, deionization creates high purity water that is similar to distilled water, and it is a rapid process.
Process :
In the context of water purification, ion exchange is a fast and reversible process in which contaminant ions in the water are replaced by ions released by an ion-exchange resin. The resin absorbs the impurity ions and must be renewed on a regular basis to return to its original ionic form.
There are two types of resin: cation-exchange and anion-exchange resins. Cation exchange resins release hydrogen (H+) ions or other positively charged ions in exchange for impurity cations found in water. Anion exchange resins release hydroxyl (OH-) ions or other negatively charged ions in exchange for impurity anions in water.
Water treatment and purification using ion exchange technology.
Ion-exchange technology can be used for water treatment and purification in three ways: cation-exchange resins for base exchange, anion-exchange resins for organic scavenging or nitrate removal, and a combination of both for deionization, which removes all ionic impurities from feedwater. The purifying process of water deionizers produces extremely high-quality water.
For many laboratory and industrial applications, high-purity water that is virtually devoid of ionic pollutants is required. Deionization can provide this grade of water.The two most common forms of deionization are:
Two-bed deionisation
Mixed-bed deionisation
Two-Bed Demineralization
As the name implies, this is a two-vessel method, one with cation resin and the other with anion resin. First, water goes via a cation exchanger. Every cation is replaced for corresponding hydrogen ions. This keeps the water electrically balanced. Water leaves the cation and goes through an anion exchange. The same concept is used here, and anions are exchanged for hydroxyl ions.
Mixed-Bed Demineralization
Instead of two separate vessels, the cation and anion resins are combined in a single pressure vessel. This approach is definitely believed to be more efficient than the two-bed plants but the regeneration mechanism involved here is more intricate. The mixed-bed plants produce better quality water than the two-bed plants. However, they are typically used when a higher level of purification is required. Following the two-bed demineralization treatment, water is refined further using the mixed-bed technique.
Demineralization water treatment has numerous applications in the fields of textiles, chemicals, boiler feed water, hospitals, swimming pools, pharmaceutical industries, and automobiles.
