Product Description

Our reputed customers can purchase from us supreme quality DM Plant that is highly acknowledged for its excellent water purification. Demineralization or deionization is the process to remove mineral salts from water by using the ion exchange process. The ions that are widely found in raw water are: Calcium (Ca2+) Chloride (Cl-), Magnesium (Mg2+) Bicarbonate (HCO3-.), Sodium (Na+) Nitrate (NO3-), Potassium (K+) Carbonate (CO32-) and Iron (Fe2+) Sulfate (SO42-). There are three ways in this ion-exchange technology of this DM Plant that can be used in water treatment and purification: first, cation-exchange resins is used to soften water by base exchange; secondly, anion-exchange resins are used for organic scavenging or nitrate removal; and thirdly, combinations of cation-exchange and anion-exchange resins are used to remove virtually all the ionic impurities that are present in the feedwater with a process known as deionization.

Features:

  • High strength

  • Durable finish standards

  • Sturdy design

  • Less maintenance


Operating Principle:
Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together. 

There are four distinct stages in the operation of Deionisers
  • Service
  • Backwashing
  • Regeneration
  • Rinse/remix
Service:

In the Service cycle the water enters the vessel and passes through the Resin bed of the respective exchanger. 

Backwashing:

After the resins are exhausted, the bed is backwashed. Backwashing is carried out by a uniform upward flow of water through the resin bed. The backwash step expands the resin bed releasing any entrapped particulate matter & removes the channeling in the resin column if occurred during the service cycle.

Regeneration

When the ion exchange resins loose all the exchangeable ions, they require regeneration to restore them back to hydrogen or hydroxyl form depending upon whether they are cation or anion resins. To achieve this 4 - 5% concentrated solution of Hydrochloric acid is used for cation resin and a 4% - 5% concentrated solution of caustic soda for anion resin. Sulphuric acid can also be used for Cation Regeneration but the concentration of acid during injection must be kept at minimum, such as to prevent calcium sulphate precipitation on the resin. 

Rinse 

 The final stage of regeneration is to rinse the resins of excess regenerant 

Advantages:
  • Easy to install & operate
  • Complete Assembly with backwash ®eneration equipment
  • Produces DM water of high purity
