DM Plant is technology used to remove salts from water. Soluble chemical compounds, when dissolved in water, become ionized; that is their molecules dissociate into positively and negatively charged components called ions. Consider common table salt, sodium chloride. In its solid form, this compound consists of one sodium atom (Na) and one chlorine atom (Cl) tightly coupled together (NaCl). When dissolved in water, however, the compound splits into two ions Na+ and Cl- A Typical two-bed DM Plant consists of two FRP vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic caution exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin.
