Dupont Filmtec SW Membranes
DuPont Filmtec SW (Seawater) series membranes are specially engineered reverse osmosis (RO) membranes designed to efficiently desalinate seawater, producing fresh, potable water essential for coastal, arid, industrial, and marine applications. These high-performance membranes achieve exceptional salt rejection rates of 99.4% or higher to meet stringent drinking water standards.
Built to withstand the high osmotic pressures of seawater, the SW membranes operate at elevated pressures ranging from 800 to 1,200 psi (55 to 83 bar). Like the BW series, they feature a wide cleaning pH range of 1 to 13, enabling effective removal of fouling and scaling, extending membrane life and performance reliability.
The DuPont Filmtec SW series includes models such as the SW30 HRLE-370/34i, SW30 XFR-400/34, and SW30 XLE-440i, making them ideal for large-scale municipal desalination plants and industrial process water treatment in power plants and refineries. These membranes offer a durable and sustainable solution for challenging seawater reverse osmosis (SWRO) applications.
