DuPont™ XP 77 IG Ultrafiltration Membrane: Superior Precision, Unmatched Reliability
The DuPont™ XP 77 IG Ultrafiltration Membrane is a high-performance filtration solution engineered for excellence in diverse water treatment applications. Featuring an advanced PVDF (polyvinylidene fluoride) hollow fiber construction, this membrane delivers exceptional filtration accuracy, robust mechanical strength, and consistent performance. Its nominal pore size of 0.03 microns ensures the efficient removal of bacteria, viruses, colloids, and other suspended particles, producing water with turbidity ≤0.1 NTU and a Slit Density Index (SDI15) ≤2.5. This makes it an ideal pretreatment for reverse osmosis (RO) systems and other critical processes
