Membranes composites à film mince pour osmose directe à haut débit et membranes à pression osmotique retardée

High flux thin-film composite forward osmosis and pressure-retarded osmosis membranes

Abstract

One aspect of the invention relates to customized thin-film composite membranes comprising: a porous support; a selective barrier; and one or more polymeric additives dispersed in the porous support in an amount from at least about 1% and about 50% by weight of the porous support. Another aspect of the invention relates to a method of fabricating a porous support comprising the steps of: preparing a polymer solution comprising a polymer, a polymeric additive, and a first liquid; contacting a surface with the polymer solution; and evaporating the liquid. Another aspect of the invention relates to the use of the thin- film composite membranes disclosed herein in osmotically driven membrane processes.
L'un des aspects de l'invention a trait à des membranes composites à film mince personnalisées comprenant: un support poreux; une barrière sélective; et un ou plusieurs additifs polymériques dispersés dans le support poreux en une quantité d'au moins environ 1% à environ 50% de son poids. Un autre aspect de l'invention a trait à la méthode de fabrication d'un support poreux consistant: à préparer une solution de polymère comprenant: un polymère, un additif polymérique et un premier liquide; à mettre en contact une surface avec ladite solution de polymère; et à faire évaporer le liquide. Un autre aspect de l'invention a trait à l'utilisation desdites membranes composites dans des processus à membranes osmotiques.
