Sanitary & Full-Fit

DOW FilmTec Membranes
DOW FILMTEC sanitary full fit reverse osmosis membrane elements specifically designed for use in sanitary, evaporator, and medical applications. The full-fit configuration minimizes stagnant areas and is an ideal choice for applications requiring a sanitary design.

  • The DOW RO-390-FF product is a premier membrane for evaporator condensate polishing.
  • HYPERSHELL HSRO heat sanitizable reverse osmosis membrane elements deliver exceptional quality water with the added capability to withstand sanitization with hot water.

Benefits of DOW FilmTec Sanitary & Full Fit RO Elements

  • Reverse Osmosis removes up to 99% of total dissolved solids.
  • Full-fit design minimizes stagnant areas for applications requiring a sanitary design.
  • HSRO elements are heat sanitizable.
  • All components comply with U.S. Food & Drug Administration standards.
  • High flux rates
  • Consistent quality from automated rolling

Permeate flow and salt rejection based on the following test conditions: 2,000 ppm NaCl, pressure specified above, 77°F (25°C) and 15% recovery.  Elements must be conditioned prior to start-up. A one-time flux loss will occur during stabilization. Listed values apply after performance stabilization.   Permeate flows for individual elements may vary +/-20%.


DOW FilmTec Heat-Sanitizable Full Fit RO Membrane Elements

DOW FILMTEC HSRO Elements are heat-sanitizable reverse osmosis elements that deliver outstanding quality water with the added capability to withstand sanitization with hot water, eliminating the need for chemical sanitizers. The full-fit configuration minimizes stagnant areas and is optimal for applications requiring a sanitary design.
