Demineralization is the process to remove mineral salts from water through the ion exchange process. Based on this process, we bring forth the best Water Demineralisation Plants for the clients across the country. Our Water Demineralisation Plant not only demineralises the water but also conserves it and saves cost. Our Water Demineralisation Plant is available in various materials and sizes. The Water Demineralisation Plants come in different types including Manually Operated and Fully Automatic, with maximum flow rate ranging from 1500 to 20000 LHP. Also, the clients can avail Water Demineralisation Plants from us in customized forms, as per their requirements.
Applications :

•  Process water for manufacturing plants
•  Boiler feed water and electronic industries
•  Hospital, hotel, Institute and more
•  Pharma industry and storage batteries
•  Beverage and food processing industry

Operating Principle :
A Typical two-bed DM Plant consists of two FRP/MS Rubber lined Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained by this process shows conductivity less than 20 µ S / cm at 25o C and total dissolved solids less than 10 ppm.
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
•  Produces DM water of high purity
•  Complete Assembly with backwash equipment
