We manufacture, export and supply Demineralisation Plant (D.M) in Kolkata, West Bengal, India. The process of Demineralisation Plant (D.M) in which the ions present in water are removed is accomplished in stages, deploying ion-exchange resins. Twin-Bed Demineralizers are used to remove ionized impurities from the water. Deionization or demineralization is the process of removing up to 95% of the dissolved mineral salts from the raw water by way of ion exchange technology. A DM plant comprises of two separate vessels internally connected in series. The first vessel is filled with strongly acidic cation (SAC) exchange resins and the second one is filled with strongly basic anion (SBA) exchange resins. Two distinctly different types of resins are utilized for this process. When water containing cations (positively charged ions such as sodium(Na+), calcium(Ca2+), magnesium (Mg2+), potassium(K+) etc.) passes through the cation resin bed, the cation resin exchanges the positive ions for hydrogen ions (H+). To keep the water electrically balanced, for every monovalent cation (e.g. Na+), one hydrogen ion is exchanged and for every divalent cation (eg., Ca2+ or Mg2+), two hydrogen ions are exchanged.
