Demineralization or Deionisation is the process of removing mineral salts from water by using the ion exchange process. Impurities that remains dissolved in water dissociate to form positive and negative charged particles known as ions. An ion-exchange vessel holds ion-exchange resin of the required type through which water is allowed to pass. The selective ions in the water are exchanged with ions or radicals loosely held by the resin. In this way, the water is passed through several vessels or a mixed bed vessel so that both positive and negative ions are removed and water is dematerialized.
We at Shubham, provide Wide range of custom-built Demineralization plants for industrial process water applications, with inherent design to conserve water, and save costs. Our unique design of D.M. plant ensures the maximum utilization of the effective surface area, uniform space and linear velocity across the resin bed which provides effective contact time between water and resin bed, yield salt free water for process equipment where water is being used for further application.
Shubham DM Plants are available in diameters from 0.225 Mts. to 4.0 Mts. with the flow rate sup to 250M3/Hr. and OBR up to 2200 M3@800 PPM TDS. These strong, pre-engineered, pre-assembled units minimize installation and start-up costs. Our D.M. Plant is acclaimed in the market for cost efficiency and consistent functioning.
A Typical two-bed DM Plant consists of two FRP/MSRL/SS Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strong acid cation(SAC) exchange resin, which replaces positive ions of salt with hydrogen ions to form respective acids, which are absorbed in next vessel by strong base anion (SBA) exchange resin. The water obtained by this process shows conductivity less than 20 µ S / cm at 25˚C and total dissolved solids less than 10 ppm.
