1. Refer to DOW FILMTEC Design Guidelines for multiple-element systems.
2. SW30-2514, SW30-2521 and SW30-2540 elements fit nominal 2.5-inch I.D. pressure vessels.
SW30-4021 and SW30-4040 elements fit nominal 4-inch I.D. pressure vessel.
DOW FILMTEC™ Membranes
DOW FILMTEC Seawater RO Elements for Marine Systems
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.
