Abstract

The inventive device comprises: means for the filtering and pre-filtering (2), (3) and (4) of water; at least one reverse osmosis module (1) consisting of a membrane with an inlet (1a), connected to a water supply, and two outlets (1b) and (1c); one of said outlets (1b) corresponds to pure osmosed water and is connected to a storage means; the other outlet (1c) corresponds to the concentrate charged with impurities. The outlet (Ic) corresponding to the concentrate, is connected to the water inlet of a water softener (15) and is combined with the volumetric metering of water at the inlet or outlet of the water softener (15), such that the production of osmosed water is authorized during a defined time period after the renewal of the volume of water contained in said water softener, while a means for controlling regeneration prevents the production of osmosed water during generation of the water softener.
