Abstract

Influence of the dope solution concentration on final membrane properties, regarding TiO2 role, was investigated. For this purpose, blended flat sheet poly(vinylidene fluoride) (PVDF)-based membranes with different proportions of poly(vinyl pyrrolidone) (PVP)/TiO2 ratios were prepared via phase inversion process. The final application of the membranes was evaluated, especially in contact with vital microbial mixed liquor, in membrane bioreactors due to antibacterial properties of TiO2 and environmentally concern of nanoparticles application. Response surface methodology (RSM) was used as a precise and multivariate technique to estimate and navigate the system performance at any experimental point within the investigation domain. Filtration properties, flux recovery ratio and (Protein flux / pure water flux: Jp/Jw) ratio of the membranes were investigated statistically to propose the formulations for the optimal performance. The correlation showed good agreement with the measured pure water flux and flux recovery ratio values of the fabricated membranes, with R2 values higher than 90%. The findings are significant since demonstrating that the loaded nano TiO2 particles around 0.5 wt% improve pure water flux, however, based on the Pareto analysis, experimental values and environmental safety concern, nanoparticles loading can be neglected in comparison with the other factors investigated in this study.
