- A Blended Nano-composite Cellulose Acetate (CA) membrane incorporated with titanium dioxide (TiO2) nanoparticles along with control CA polymeric membrane was prepared by phase inversion method to evaluate the performance of Forward Osmosis (FO) membrane system. TiO2 nanoparticles were added into the CA matrix to improve the desalination performance of the CA membrane and enhancing hydrophilicity and stability. The membranes were fabricated by casting of CA/TiO2 with PVP as a pore former on a polyester woven mesh. The performance of the FO membrane was tested using 1M NaCl as the draw solution (DS) and Deionised (DI) water as the feed solution (FS) in FO mode. The water flux obtained by CA polymeric membrane was 14.5 LMH, while it was 26.6 LMH, 30.5 LMH, and 21.71 LMH for blended nano-composite CA membrane at TiO2 concentrations of 0.5 wt%, 1 wt% and 1.5 wt%, respectively. The blended nano-composite membrane prepared using CA substrate embedded with 1 wt% exhibited the most promising results by showing high water permeability. The enhanced hydrophilicity and favourable structure formed are the main factors resulting in high water flux of nano-composite substrate. Although, increase in TiO2 nanoparticles from 0.5 wt% to 1.5 wt% resulted in low water permeability. Based on the results obtained in this work, it can be concluded that adding an appropriate amount of TiO2 nanoparticles into CA substrate could potentially improve the performance of CA polymeric membrane and improve the membrane permeability, mechanical strength and stability.
