De Mineralised Plants

Demineralization is the process of removing mineral salts from water by using the ion exchange process.

Demineralised 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 nanofiltration)
•     Electrodyalisis
•     Or other technologies.

Demineralization ( DM ) Water Treatment Plants

Demineralized water also known as Deionized 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, sulphate, 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. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.

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.

The water free from any mineral is called De- Mineralised Water (D.M.Water). Naturally occurring water has various salts in dilute form which are called dissolved solids (TDS) . When the water having such mineral is required to be free from this, it is to be treated in Ion Exchange Resins column (H form) which adsorbs the positively charge ion. Now the cations free passed through Anion Resin Column (OH form) which adsorbs the negatively charged anions and water free from the total ions shall comes out from the system.
