🏭 FilmTec™ BW30HR-440 High Rejection Brackish Water RO Membrane
The FilmTec™ BW30HR-440 (High Rejection) is a premium 8-inch diameter reverse osmosis element engineered for high-purity industrial and municipal water treatment. It combines an industry-leading 440 square feet of active membrane area with DuPont’s most advanced brackish water membrane chemistry. This high-productivity design allows system operators to achieve maximum salt rejection and permeate quality while potentially reducing the total number of elements required in a system, thereby lowering capital and operational expenses.
Equipped with a 28-mil feed spacer, the BW30HR-440 is designed to balance high flux with excellent cleanability, making it ideal for plant managers seeking long-term consistency and fouling resistance. Its robust fiberglass hard-shell construction ensures structural integrity in high-pressure applications. This element is specifically optimized to deliver superior rejection of critical solutes, including silica, boron, ammonium, and nitrate, ensuring the highest level of permeate purity for demanding process waters.
