Description

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.
