For many years, Distillation was the only method available for complete removal of soluble salts from water. However, with the advent of the development of the commercial cation -Exchange and Anion exchange Resin, it has been passable to produce De-ionised water of highest purity by a two step Ion -exchange process.

SONA CHEMICALS demineralizer consists of acid/ alkali proof pressure vessel with internal fittings and initial change of Caption and Anion exchanger. A set of regeneration equipment, Hydraulic ejectors, acid and alkali tanks, conductivity meter helps to provide pure salt free water, which is required for industrial purpose.

De-mineralization technology is the proven process for treatment of water. A DM Water System produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. Demineralized Water System finds wide application in the field of steam, power, process, and cooling.

Demineralization of water can be better achieved by employing a “Mixed Bed”of cationic and Anionic Resins this method produces an effluent which is far superior to that produced by the two bed operation. When water is passed through a mix bed consisting of Anion and cation exchange resins, each pair of contracting resin particles functions as a stage in the treatment and thus the total effect is that of a multiple- cycle -deionization. 

When the resins are exhausted the bed is backwashed when the two resins are separated in different layers due to difference in their densities. Then the resin are separately regenerated, washed and mixed again by injecting air and reused for a fresh cycle.
