Product Description

What is deminerlization ?

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

Distillation

De-ionization

Membrane filtration (reverse osmosis or nano filtration)

Electro-dialysis

Or other technologies.


 is Deminerlized before using it for industry purpose?

Distilled water contains dissolved silica. If distilled water is fed to boiler and turbine section it will unbalance the temperature in boiler section from higher to lower temperature or lower to higher temperature.Distilled water contains dissolved silica. DM water is applicable to boilers feed Water, Textiles,Pharmaceuticals, Chemicals, Breweries, Swimming pools, Potable Water,Hospitals, Automobile, and Battery, Fertilizers.


Why to choose us?

We provide our clients a high-quality Deminerlization Water Plant. Our offered deminerlization plant removes mineral salts from water by using theion-exchange process. This demineralization plant is provided in customized options in order to fulfill the needs of clientele.  Today, we are regarded as one of the trusted Demineralization Water Plant Exporters.

Working Principle

A DM Water System produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. Deminerlized water also known as De-ionized 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, sulfate, nitrate, etc are common ions present in Water. Deioniztion 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. De-minerlization technology is the proven process for treatment of Water.

Ion exchange process is widely accepted for water treatment and purification.(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).
Ion-exchange is a rapid and reversible process in which impurity ions presenting the water are replaced by ions released by an ion-exchange resin.


There are two basic types of resin.

Cation exchange resins

Anion exchange resins

Cation exchange resins will release Hydrogen(H+) ions or other positively charged ions in exchange for impurity cations present in the water. Anion exchange resins will release hydroxide (OH-) ions or other negatively charged ions in exchange for impurity anions present in the water.

There are three ways in which ion-exchange technology can be used in water treatment and purification:

Cation exchange resins alone can be employed to soften water by Base Exchange;
Anion-exchange resins alone can be used for organic scavenging or nitrate removal;
Combinations of cation and anion-exchange resins can be used to remove virtually all the ionic impurities present in the feed water, a process known as de-ionization. Water de-ionizers purification process results in water of exceptionally high quality.

For many laboratory and industrial applications,high-purity Water which is essentially free from ionic contaminants is required. Water of this quality can be produced by de-ionization. The two most common types of ionization

Two bed deionization

Mixed bed deionization

Two Bed Deionization:

The two-bed deionizer consists of two vessels - one containing a cation-exchangeres in in the hydrogen (H+) form and the other containing an anion resin in the hydroxyl (OH-) form. Water flows through the cation column, whereupon all the cations are exchanged for hydrogen ions. To keep the Water electrical lybalanced, for every mono valent cation, e.g. Na+, one hydrogen ion is exchanged and for every divalent cation, e.g. Ca2+, or Mg2+, two hydrogen ions are exchanged. The same principle applies when considering anion-exchange. The decationised Water then flows through the anion column. This time, all the negatively charged ions are exchanged for hydroxide ions which then combine with the hydrogen ions to form Water (H2O).

Mixed Bed  Deionization

Inmixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained in a single pressure vessel. The thoroughmixture of cation-exchangers and anion-exchangers in a single column makes amixed-bed deionizer equivalent to a lengthy series of two-bed plants. As aresult, the Water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant. Although more efficient inpurifying the incoming feed water, mixed-bed plants are more sensitive to impurities in the Water supply and involve a more complicated regeneration process.Mixed-bed deionizers are normally used to “polish' the Water to higher levels of purity after it has been initially treated by either a two-bed deionizer ora reverse osmosis unit.

 Our unique design of dimineralizing plant ensures the maximum utilization of the effective surface area, uniform space and linear velocity across the resin bed which provides effective contact time between water and resin bed yield soft water and prevent any precipitation and scale formation on the surface of heat exchanges and any process equipment where water is being used for further application.

 The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. For the purpose of regeneration resin is separated by backwash, regenerated separately with 5%HCl and 5%NaOH and mixed after washing.
