Demineraliser

Water being universal solvent often dissolved undesirable minerals such as calcium, magnesium, sodium salts, etc., which are harmful for industrial applications. The concept of demineralization aims at providing treated water devoid of these dissolved solids.

HOW IT DOES

The process of demineralization revolves around two distinct stages. One in which hydrogen based cation exchange resins chemically react with dissolved salt particles of untreated water and exchange hydrogen ion for cations, leaving water dilute acids such as hydrochloric, sulfuric, carbonic etc. where as in the second stage anion exchange resins take the anions and provide hydroxyl ions (OH -) thereby leaving just water, which is the treated water. Regeneration of cation and anion resins is easy and simple. This process, reverse ion-exchange basically aims at making the resins, to the original status with acid- alkaline treatments

There are both standard types and tailor made ones for the given needs. Taking into account, the expected production of treated water quantity and the quality of the available raw water, quantities of resins are arrived at. Based on this resin quantity two vessels made of rubber lined mild steel, with distribution and collecting systems are designed, the first vessel has cation resins wherein raw water is semi processed the second vessel with anion resins, process this water and produces the treated water.
