Abstract

The invention relates to a process for treating water that contains at least calcium and/or magnesium salts through membranes of reverse osmosis type, said process comprising at least one step of recovering water that is at least partly desalinated, a step of recovering a concentrate originating from said membranes and that contains bicarbonates, a step of injecting CO2 or an acid into said at least partly desalinated water, and a step of remineralization of said at least partly desalinated water within a remineralization reactor. According to the invention, such a process comprises: – a step of decarbonation of said concentrate so as to form carbonates, and – a step of recycling at least one portion of said carbonates within said remineralization reactor.
