DuPont FilmTec™ SW30XLE-400i Seawater RO Membrane

The DuPont FilmTec™ SW30XLE-400i is an advanced, Extra Low Energy Seawater Reverse Osmosis (SWRO) Membrane engineered to significantly reduce the cost of seawater desalination. Utilizing state-of-the-art Polyamide Thin-Film Composite technology, this 8" x 40" element is specifically designed to operate at significantly lower feed pressures than standard seawater membranes. With an optimal 400 square feet of active membrane area, it delivers a massive permeate flow rate of 9,000 GPD while maintaining a highly dependable 99.7% stabilized salt rejection rate, making it an excellent choice for municipal and industrial desalination facilities looking to maximize productivity while minimizing energy expenditure.

Constructed for durability in demanding marine environments, the SW30XLE-400i features a standard 28-mil feed spacer that effectively balances fouling resistance with maximum active area. The "i" designation indicates the inclusion of DuPont's patented iLEC™ (Interlocking End Caps). This innovative design creates a direct, mechanically sealed connection between elements loaded within the same pressure vessel. By eliminating the need for interconnecting O-rings, the iLEC technology drastically reduces the risk of internal leakage and bypass, ensuring consistent, high-purity permeate water quality throughout the lifespan of the system.
