SW30XFR-400/34 DuPont FilmTec 7,500 GPD at 800 PSI 8 x 40 inch 99.8% Rejection Membranes

DuPont FilmTec SW30XFR-400/34 Seawater RO Membrane (7,500 GPD)

For large-scale desalination facilities and industrial water treatment systems dealing with challenging or high-fouling feed water, the DuPont FilmTec SW30XFR-400/34 provides a highly durable and efficient reverse osmosis solution. Engineered specifically for seawater desalination, this premium 8-inch by 40-inch membrane element utilizes an advanced Extra Fouling Resistant (XFR) thin-film composite chemistry. This specialized polyamide design provides exceptional resistance to biological and colloidal fouling, significantly reducing the frequency of chemical cleanings (Clean-In-Place) while maintaining an outstanding balance of permeate quality and system energy consumption.

To further combat fouling and extend operational lifespan, the SW30XFR-400/34 incorporates a thicker 34-mil feed spacer alongside an expansive 400 square feet of active membrane surface area. When evaluated under standard test conditions at an applied pressure of 800 PSI, this high-performance element delivers a robust nominal permeate flow rate of 7,500 gallons per day (GPD) with an exceptional stabilized salt rejection rate of 99.8%. Capable of handling a wide pH range during cleaning cycles, this heavy-duty spiral-wound membrane ensures maximum facility uptime, lower long-term operating costs, and highly reliable potable water production in demanding marine and municipal environments.
