DuPont FilmTec RO Membranes for Every Application

DuPont FilmTec Membrane Elements

FilmTec RO membrane elements offer superior quality and performance for the separation of contaminants in concentrated water resulting in purified, clean drinking water. We supply DuPont FilmTec membranes for any application. These elements offer extremely high rejection capabilities, and utilize less energy to produce purified water than conventional elements using reverse osmosis (RO) and nanofiltration (NF) technologies. These membranes are exceptionally efficient in water treatment applications that include industrial, commercial, municipal, and consumer-related concerns.
