Abrégé

Method implementing resins for treating organic compounds in industrial wastewaters, said method comprising the steps of: during treatment cycles, pumping an industrial wastewater into a reactor containing an ion-exchange resin, letting said organic compounds being captured onto said resin and obtaining a treated wastewater at an outlet of said reactor; during regeneration cycles for restoring removal capacity of said resin, stopping said pumping of said industrial wastewater into said reactor, pumping a regeneration liquid into said reactor, letting said regeneration liquid desorb the organic compounds captured onto the resin, and obtaining an eluate containing said desorbed organic matter; recycling said eluate for using it as said regeneration liquid, characterized in that said resin is a strong base anionic ion exchange resin, and said regeneration liquid is an hypersaline solution.
