DuPont FilmTec SW30XLE-440i Seawater RO Membrane
The DuPont FilmTec SW30XLE-440i is a high-productivity Extra Low Energy Seawater Reverse Osmosis Element designed to reduce operating costs in desalination plants. As part of the "XLE" (Extra Low Energy) family, this membrane delivers high salt rejection while operating at lower feed pressures than standard seawater elements, resulting in significant energy savings. Its large 440 ft² active area maximizes production capacity, making it an ideal choice for large-scale municipal and industrial systems where efficiency is critical
The "i" suffix denotes the inclusion of iLEC™ (Interlocking End Caps) technology. This innovative design replaces standard sliding couplers with a direct, leak-tight mechanical seal between elements. By eliminating O-rings, iLEC reduces the risk of permeate contamination and simplifies installation. The SW30XLE-440i is optimized for medium-salinity seawater and cold water applications, offering a sustainable solution for producing high-quality permeate with lower power consumption.
