Process for the purification of water by passing it through a mixture of a cation exchanger and an anion exchanger characterized by the fact that the ion exchangers are arranged in a purification column above a horizontal porous plane, whereas the output for the regeneration solutions of the ion exchangers is established above the porous plane, at a level corresponding to the separation plane of the ion exchangers, when these have been separated into two superimposed layers, arriving at the solutions of regeneration by the upper part or by the lower part of said column according to the ion exchanger to be regenerated.
