In this study flat sheet mixed-matrix nanocomposite membranes (MMNM) were synthesized via phase inversion method in which γ-alumina (Al2O3) nanoparticle used as additive and polyacrylonitrile (PAN) polymer used as membrane matrix. The pure water flux, fouling and dye rejection of fabricated membranes were characterized, using cross flow filtration system. The raw membranes (membrane without alumina nanoparticle) showed enhanced pure water flux and dye rejection in comparison with other studies that were reported for pure PAN. The γ-alumina nanoparticles were blended in different weight percent with PAN membrane matrix. Addition of nanoparticles increased pure water flux and improved antifouling properties of membranes. All membranes whether raw or nanocomposite displayed great ability in dye rejection.
