This thesis was conducted for the purpose of enhancement of RO membrane performance, where MgSiO₃ NPs were attached to the surface of TFC membrane with AMPS monomer as a bridging agent via free radical grafting technique. MgSiO₃ NPs modified AMPS-g-TFC membrane showed superior mechanical and thermal stabilities while it has a high hydrophilic surface, as the contact angle with water reached (~45.9).Microscopic and morphology of modified nanocomposite membrane were examined using FT-IR, XRD, and SEM. Also water flux were assessed, which gave about 28.2 L/m2.h, and a salt rejection of 95.5% for a feed saline water (2000 ppm of NaCl) at an applied pressure about 15 bar with a 32% increase in water flux comparing to the pristine TFC membrane. Results demonstrates that the MgSiO₃ NPs modified AMPS-g-TFC membrane could remarkably enhance selectivity, water permeability and surface hydrophilic characters of RO membrane
