SW30HRLE-370/34i DuPont FilmTec 6,700 GPD at 800 PSI 8 x 40 inch Membranes

DuPont FilmTec SW30HRLE-370/34i Seawater RO Membrane (6,700 GPD)

The DuPont FilmTec SW30HRLE-370/34i is a premium, high-rejection Seawater Reverse Osmosis (SWRO) membrane element engineered for demanding municipal and industrial desalination applications. Fabricated with advanced polyamide thin-film composite technology, this 8-inch by 40-inch spiral-wound element is specifically designed for high-fouling or challenging feedwater conditions. It features a wide 34-mil feed spacer that minimizes the impact of colloidal fouling, reduces the pressure drop across the vessel, and significantly enhances the effectiveness of routine cleanings. To ensure superior system reliability, the element integrates DuPont's distinct iLEC (Interlocking Endcaps) technology, which eliminates the need for interconnecting O-rings, thereby reducing operational costs and preventing internal leaks that can degrade permeate quality.

Delivering an excellent balance of energy consumption and high-productivity purification, the SW30HRLE-370/34i features 370 square feet of active membrane area. Evaluated under standard test conditions at an applied pressure of 800 PSI, this robust element produces a massive nominal permeate flow rate of 6,700 gallons per day (GPD) while maintaining an outstanding 99.80% stabilized salt rejection rate and 92% boron rejection. Rated for a maximum operating pressure of 1,200 PSI, it provides resilient, long-lasting performance for large-scale seawater reverse osmosis (SWRO) plants, offshore facilities, and heavy-duty coastal desalination systems requiring unwavering water purity and consistent flux.
