Title (EN) HIGH PERFORMANCE POSITIVELY CHARGED COMPOSITE MEMBRANES AND THEIR USE IN NANOFILTRATION PROCESSES
(FR) MEMBRANES COMPOSITES CHARGÉES POSITIVEMENT À PERFORMANCE ÉLEVÉE ET LEUR UTILISATION DANS DES PROCÉDÉS DE NANOFILTRATION
Abstract:
(EN) The present invention is directed to positively charged nanofiltration (NF) membranes comprising a substrate layer (S) based on a sulfonated polymer and a positively charged film layer (F) on top of said substrate, and to a method for their preparation. Furthermore, the present invention is directed to nanofiltration processes making use of said composite membrane.
(FR) La présente invention concerne des membranes de nanofiltration (NF) chargées positivement comprenant une couche de substrat (S) basée sur un polymère sulfoné et une couche de film chargée positivement (F) sur le dessus dudit substrat, et un procédé pour leur préparation. De plus, la présente invention concerne des procédés de nanofiltration utilisant ladite membrane composite.
