Demineralization Plants

Our company has designed a demineralization plant which is very well suited for purifying all sorts of impurities in water. Because the plant uses advanced technology so this is very useful for removing harmful chemicals and toxics from the water. Our company is known to be one of the famous demineralization plant manufacturers in India who provide the safest form of water that is used for various purposes.

Demineralization Plant

Demineralization is the process of removing mineral salts from Water by using the ion exchange process. Demineralised Water is Water completely free ( or almost ) of dissolved minerals as a result of one of the following processes :

  • Distillation
  • Deionization
  • Membrane filtration (reverse osmosis or nanofiltration)
  • Electrodyalisis
  • Or other technologies.

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. A DM 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.


Raw Water is passed via two small polystyrene bead filled (ion exchange resins) beds. While the cations get exchanged with hydrogen ions in first bed, the anions are exchanged with hydroxyl ions, in the second one.

In the context of Water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the Water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively-charged ions are called cations and are usually metals; negatively-charged ions are called anions and are usually non-metals).


  • Variety of cost effective standard models.
  • Improved aesthetics and rugged design.
  • User friendly, low maintenance and easy to install.
  • Simpler distribution and collection systems.
  • Quick availability.
  • Pre dispatch assembly check.
  • The multiport valves are top mounted as well as side mounted with the necessary high pressure rating PVC piping.
  • Single valve operation as compared to the six valves in conventional filters
  • Each operating step is clearly marked on the valve, thereby eliminating chances of error in the operating sequence.
  • Single valve assembly, with its simplified frontal Piping, simpler distribution collecting systems is Very easy to install.
  • Rust free
  • Less power consumption
  • Durable
  • Economical
  • High shelf life

The basic DM plant must have minimum two resin columns, Cation and Anion. The cation unit contains resins, which are in H+ form and Anion resins in service cycle are in OH- form. The filtered raw water, when passed through a two bed DM plant, cation resins exchange all cations in water and the salts are converted to respective acids. This acidic water is passed through the anion resins, which exchanges the anions and the pure water is achieved.The water coming out of Anion unit generally has TDS less than 40 PPM & Hardness less than 1 PPM.

The two bed DM plant generally consists of two pressure vessels for accommodating cation and anion resins, nest of valves or multiport valve, piping, chemical tanks, testing kit and conductivity meter. Depending on raw water & treated water quality desired, the other units get added for a specific purpose.
