The DuPont FilmTec SW30-4040 is a high-performance 4-inch seawater reverse osmosis membrane element designed for commercial and industrial desalination systems. Built with advanced Thin Film Composite (TFC) membrane technology, it delivers excellent salt rejection and consistent permeate flow even in high-salinity seawater conditions.
This membrane is engineered for reliability and durability, making it ideal for small desalination plants, marine applications, and industrial water purification systems where high-quality permeate and long membrane life are required.
