DOW FILMTEC™ Membranes
DOW FILMTEC Seawater RO Elements for Marine Systems
Features
Improved DOW FILMTEC™ seawater reverse osmosis elements offer the highest
productivity while maintaining excellent salt rejection.
•
DOW FILMTEC SW30 membrane elements have the highest flow rates available to
meet the water demands of both sea-based and land-based desalinators.
•
DOW FILMTEC SW30 elements may also be operated at lower pressure to reduce
pump size, cost and operating expenses.
•
Improved DOW FILMTEC seawater membrane combined with automated, precision
element fabrication result in the most consistent product performance available.
