DOW FILMTEC™ SW30-2514 Seawater RO Elements for Watermakers and Marine Systems
DOW FILMTEC SW30-2514 elements have one of the highest flow rates available to meet the water demands of both sea-based and land-based desalinators. Commonly used in on-board Watermakers to create drinking water from seawater for yachts, boats, and cruise ships, DOW FILMTEC marine SWRO elements offer the highest productivity while maintaining excellent salt rejection. DOW FILMTEC SW30 elements may also be operated at lower pressure to reduce pump size, cost, and operating expenses
DOW FILMTEC SW30-2514 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
