Sanitary & Full-Fit

DOW FilmTec Membranes

DOW FILMTEC sanitary full fit reverse osmosis membrane elements are specifically designed for sanitary, evaporator, and medical applications. The full-fit configuration minimizes stagnant areas and is ideal 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 and withstand sanitization with hot water.

DOW FilmTec Sanitiary Grade Full Fit RO Membrane Elements

DOW FILMTEC RO Full Fit elements deliver high flux and outstanding quality water for applications requiring sanitary-grade membrane elements. The full-fit configuration minimizes stagnant areas and is optimal for applications requiring a sanitary design.   DOW FILMTEC™ RO-390-FF elements are the premier membrane for evaporator condensate polishing.

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.
