DOW Filmtec RO Membrane

A critical component of the FilmTec™ family of products, DuPont Water Solutions reverse osmosis water treatment technology supports high-quality, top-performing water purification in consumer, commercial, municipal, and industrial water treatment systems across the globe.

Our FilmTec™ RO elements house spiral-wound, thin-film composite polyamide membranes. Typically, a spiral-wound configuration means lower replacement costs, simpler plumbing systems, easier maintenance, and greater design freedom than other configurations, such as tubular, plate-and-frame, and hollow-fiber module designs. Our RO elements are manufactured using the most highly advanced, automated manufacturing technology in the industry, which results in maximum uniformity and minimized element-to-element differences. Our rigorous, extensive quality testing ensures that FilmTec™ elements meet our high fabrication standard.
