The review of existent methods of high-purity water production in industrial conditions is given. It is shown, that electro-ion-exchange technology is the alternative to the use of mixed-bed polisher. The evaluation of the methods of post-treatment stage efficiency increasing in MBP is performed. The correlation between the charging rate of particles of ion-exchangers and the ion-exchangers mixed media expansion degree is set. The criterion of determination of the optimum conditions of ion-exchangers mixture separation during the regeneration of MBP is set. The results of investigations of the cation- and anion-exchange resins mixture separation conditions on a pilot plant are given.

Key words: high purify water production, membrane treatment, electroionexchange technology, mixed bed filter, ion-exchange resins separation.
