Industrial DM plants consists of cation unit and anion unit placed one after other in series. The cation unit is charged with strong acid cation resin & anion unit is charged with strong base unit. Industrial DM plants remove all the anions & cations from the water. Conductivity of the treated water at the out let of Industrial DM Plant shall be less than 1 micro mhos per cm. The cation resin is regenerated with Hydrochloric acid & anion resin with Caustic solution. Industrial Mixed Bed DM Plant is called as polisher. Two bed DM Plant out let Conductivity will be less than 30 micro mhos, this 30 will be bring down in Mixed bed DM plant. Air is required in Mixed Bed DM plant to mix resins after regeneration. Industrial DM plant vessels are made up of Mild steel rubber lining. Industrial DM Plants are used in the following areas.
Industrial DM Plant Applications:
- Battery top up
- Laboratory and research institutions
- Pharmaceuticals
- Chemicals
- Electroplating and mirror silvering
