| titleOfInvention | WATER PREPARATION METHOD |
| abstract | The invention relates to the field of water treatment, in particular to the ion-exchange technology of desalting, softening water with a simultaneous decrease in its alkalinity and can be used in the power industry to obtain high-quality conditioned water suitable for use as a heat carrier. The initial water is desalted by treatment on H-filters by successive passing through a carboxyl cation exchanger and a sulfonic cation exchanger, and then on OH-filters. Softened water is prepared by sequential or parallel passing of the initial water through the carboxyl cation and sulfonic cation exchangers, which are pretreated with the spent regeneration solution of OH filters. The H-filters spent during water softening are regenerated with an acid solution at stoichiometric costs of the reagent by passing the regeneration solution first through the sulfonic cation exchanger and then through the carboxyl cation exchanger. The implementation of the method allows to reduce the content of sodium ions in demineralized water by 80 times, stabilize and reduce the alkalinity of softened water to values of 0.29-0.36 mg-eq / dm3. At the same time, the working capacity of the cation exchangers increases by 1.7-3.3 times, which leads to an increase in the total production of demineralized and softened water by 1.4-3.7 times. |
