The process of mineral salts removal from water with the help of ion exchanging process is known as water demineralisation. After the demineralisation process, the resultant water becomes almost totally free of dissolved salt minerals. The negative and positive ions of various elements get removed, leaving the pure H2O molecules behind.

The positive ions or cations include elements like Copper, Iron, Calcium and Magnesium, while the negative ions or anions include Sulphates and Chlorides.



Purpose:

The primary purpose of a Demineralisation Plant is to remove impurities of water so that oxidation of metal and scale formation can be prevented. The processed water can be used anywhere without worrying about metal corrosion.


Technology :

We, at Ecologics India, are one of the leading DM plants manufacturers of India and can provide a wide array of custom made DM plants for industrial applications. Our uniquely designed DM plants ensure maximum surface area utilization as well as inherent designs for water conservation.

Methodology:

Demineralisation is a complex process compared to other water rectification processes. Here are brief details about all of its steps.


Principle


  • A two-bed DM plant has two FRM/MSRL pressure vessels in a series connection. The first vessel contains strong acid cations (SAC) of high capacity. The second vessel contains a strong base anion (SBA).

  • The acid cations replace salt’s positive ion with hydrogen ion and form acid. This acid then gets absorbed by base anions in the second vessel.

  • The resultant water contains solids at less than 10 ppm rate. It also shows lesser conductivity at 20 µ S / cm at 25˚C.

Cation Resins


Cation resins with positive charge get rid of positively charged contaminants from the water. Mainly strong and weak acids are used as cation resins.

Hardness Removal


SAC resins are responsible for water’s hardness removal. These resins are used in almost every type of water purifier, including residential units also. SAC resin removes scale-forming Magnesium and Calcium ions and turns them into neutral Sodium ions.

Softening and Dealkalization


Weak acid cations can remove alkalinity and hardness simultaneously. They also separate some percentage of total dissolved solids (TDS). Generally, around 80% of temporary hardness gets removed by WAC.

Anion Resins


Anion resins with negative charge remove negatively charged contaminants from water. Strong base anions (SBA) and weak base anions (WBA) work as anion resins. SBA, in association with SAC, can reduce TDS and harmful minerals in the water.

DM Plants Regeneration


Depending upon usage and water output, resins in a demineralization plant can become exhausted and lose its capability of deionization. Their capability of iconic mineral removal reaches the lowest level. They have to be recharged with H+ and OH- ions.
