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