Zusammenfassung:Nanofiltration devices and systems, along with improved methods to convert reverse osmosis membranes to nanofiltration membranes, are disclosed. Nanofiltration devices and nanofiltration systems with improved salt permeability performance are derived from incorporating controlled heating or controlled cooling of the hypochlorite solution temperature thereby producing a more consistent manufacturing process. L'invention concerne des dispositifs et des systèmes de nanofiltration, ainsi que des procédés améliorés pour convertir des membranes d'osmose inverse en membranes de nanofiltration. Des dispositifs de nanofiltration et des systèmes de nanofiltration présentant des performances améliorées de perméabilité au sel résultent de l'incorporation d'un chauffage contrôlé ou d'un refroidissement contrôlé de la température de la solution d'hypochlorite, d'où l'obtention d'un procédé de fabrication plus cohérent.
