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.
