Water for steam boilers and other purposes is demineralized in our country by the means of ion-exchange technologies, consisting of two-three stages of cationic and anionic filters. Operation experience of ion-exchange technology is about 60 years. Currently improvement of ion exchange technology and increase of ion-exchanger efficiency is performed is the way of counter-current ion-exchanger designing and improvement of quality of water treatment ion-exchange resins.
