Demineralization Plant



Our organization holds expertise in designing, erecting and commissioning highly efficient Demineralization Plant, also known as DM Plants. These plants are used for the removal of impurities from the water for industrial use. These Demineralization Water Treatment Systems are considered ideal for places when feed water TDS is low and low conductivity product water is required. These plants can also be customized based on the specific requirements of the customer. Further, the range is stringently checked on various parameters to ensure its compliance to set industry standards and capability in removing cations, anions or strong acid anions from the water.

This typical process involves the removal of Cations (e.g. calcium, magnesium, sodium, potassium, iron and other heavy metals) by a bed of Strong Acid Cation (SAC) ion exchange resin followed by a second bed of Strong Base Anion (SBA) Resin for the removal of all anions (e.g. Bicarbonate Alkalinity, Chloride, sulfate, Nitrate, Silica etc.) or a second bed of Weak Base Anion (WBA) Resin for the removal of Strong Acid Anions (e.g. chloride, sulfate and nitrate). The Demineralization process is also enhanced for production of High Purity water by providing mixed bed ion exchange column in addition to normal de-ionization columns.


About Demineralization Plant

  • In the systems, a strong Acid Cation (SAC) ion exchange resin is followed by a second bed of Strong Base Anion (SBA) resin for the removal of all anions(e.g.Bicarbonate Alkalinity, Chloride, sulfate, Nitrate, Silica and etc.)
  • A second bed of Weak Base Anion (WBA) resin takes place for the removal of Strong Acid Anions (e.g. chloride, sulfate and nitrate)
  • The Demineralization process is also known as Deionization
  • It is an economical option when feed water TDS is low and low conductivity product water is required
