DUPONT Product Data Sheet Description FilmTecTM Membranes FilmTecTM Seawater RO Elements for Commercial Systems Improved FilmTec TM Seawater Reverse Osmosis Elements offer the highest productivity while maintaining excellent salt rejection. • FilmTecTM SW30 Membrane Elements have the highest flow rates available to meet the water demands of both sea-based and land-based desalinators. FilmTecTM SW30 Elements may also be operated at lower pressure to reduce pump size, cost and operating expenses. Improved FilmTecTM seawater membrane combined with automated, precision element fabrication result in the most consistent product performance available.

Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure. Please refer to Dechlorinating Feedwater (Form No. 45-D01569-en) for more information.
