DM Plant
A DM plant generally consists of cation, anion, and mixed bed exchangers. Any ions in the final water from this process consist essentially of hydrogen ions and hydroxide ions, which recombine to form pure water. Very pure DM water becomes highly corrosive once it absorbs oxygen from the atmosphere because of its very high affinity for oxygen.
The capacity of the DM plant is dictated by the type and quantity of salts in the raw water input. However, some storage is essential as the DM plant may be down for maintenance. For this purpose, a storage tank is installed from which DM water is continuously withdrawn for boiler make-up. The storage tank for DM water is made from materials not affected by corrosive water, such as PVC. The piping and valves are generally of stainless steel. Sometimes, a steam blanketing arrangement or stainless steel doughnut float is provided on top of the water in the tank to avoid contact with air. DM water make-up is generally added at the steam space of the surface condenser. This arrangement not only sprays the water but also DM water gets deaerated, with the dissolved gases being removed by an air ejector attached to the condenser.
We are instrumental in providing our clients with DM Plant that makes use of Ion exchange technology, which is used to remove salts (cations and anions) from the 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.
We are one of the trusted fabricators of DM Plant, which is based on Ion exchange technology for removal of salts (cations and anions). This removal process of salts from the water soluble chemical compounds when these are dissolved in the water. Our DM plants are fabricated using corrosion resistant material and can be customized according to the requirements of the clients. These are made available at market leading prices.
