Abstract

Procedure and installation to desalinate solutions that have a high saline component with the use of ion exchange resins, characterized by the fact of passing the aqueous solution successively through a strongly basic anion exchange resin, so that the treated water contains all the cations in the water before treatment transformed into bicarbonates while the mineral acidity is absorbed by the strongly basic anion exchange resin, through a weakly acidic cation exchange resin so that it absorbs all the cations and releases the acid carbonic, through a strongly acidic cation exchange resin and finally through a weakly basic anion exchange resin so that the cations and anions that come from the passage through the first two gases of the treatment are retained and water is obtained debugged containing only e free carbonic acid.
