Deminarization plants consist 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 the strong base unit. D.M. plants remove all the anions & cations from the water.
The cation resin is regenerated with Hydrochloric acid & anion resin with a Caustic solution. Then the cation unit is rinsed with feed water and anion unit with deionised water till the acceptable water quality is achieved.
