Demineralization Plants

Product Details:

Demineralization is the process of removing mineral salts from Water by using the ion exchange process. Demineralized 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 nano filtration)
• Electro-dialysis Or other technologies.

Why water is de mineralized 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.

Working Principle
A DM Water System produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. De mineralized 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. 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. De-mineralization 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 present in 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 hydroxyl (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.

What is water demineralization?

Demineralization is a type of water purification. While it can refer to any treatment process that removes minerals from water, the term demineralization is typically reserved specifically for ion exchange (IX) processes used for near total removal of ionic mineral contaminants. Often, the terms demineralization and deionization are used interchangeably.

IX demineralization utilizes both cation and anion exchange resins, sometimes even in the same column or bed. Following demineralization, the treated water will be of a high level of purity comparable to distilled water, but typically at a much lower cost.

What’s included in a basic demineralization system?

The specific design and components of an IX demineralization system can vary from one application to the next based on process conditions and composition of the stream to be treated. Still, most demineralization systems will include the following components:

• One or more IX columns
• Regenerant dosing system
• Chemical feed storage tanks
• PLC, control valves and piping
• IX resins

There is some flexibility in the configuration of a demineralization system in order to optimally meet various process conditions and purity goals. In designing a demineralization system, consideration should be given to variability of the feed water, level of purity needed, system footprint, tolerance for ion leakage (in particular sodium and silica), and chemical feed requirements, among other factors.

How does demineralization work

As we’ve said, demineralization typically refers to the removal of dissolved mineral solids through an IX process. But before we get deeper into how demineralization works, we’ll go over the basic principles of an IX reaction.

In the presence of water, minerals and salts dissociate into their constituent ions. These dissolved solids consist of negatively-charged ions known as anions, and positively-charged ions known as cations, each of which are attracted to counterions (or ions of an opposing charge). Present within an IX column is a resin which consists of plastic beads to which an ionic functional group has been bound. These functional groups loosely hold ions of an opposing charge through mutual electrostatic attraction. During an active IX cycle, a water with dissolved ions is introduced to the resin. The ions in solution will exchange places with the  ions on the resin beads, clinging to the resin’s functional groups even as the resulting solution is drained away. IX happens when one ion has greater affinity for the functional group than the ion that is already present. The specific ionic contaminants present will dictate whether anionic and/or cationic resin types are needed.

In a typical IX reaction, the exchange of ions simply results in the replacement of contaminant ions with other, less objectionable, ions. In an IX sodium softening system, for example, the objective is to remove hardness ions (e.g. Ca²⁺ or Mg²⁺) from solution by replacing them with sodium ions (Na⁺). As a result, the treated solution will have little to no hardness, but it will contain a greater concentration of sodium ions.

While this is acceptable for many applications, some processes demand near total removal of dissolved solids. That’s where demineralization comes in. In demineralization, cations in the feed water are exchanged for hydrogen (H⁺) ions and cations are exchanged for hydroxyl (OH^–) ions.  The result is water:  H⁺ + OH^-OH → H₂O. In general, demineralization IX systems are available in either two-bed or mixed-bed configurations, as detailed below.
