[en] This work explores the optimization of poly (ether sulfone) (PES) mixed matrix membranes including titanium dioxide/bismuth ferrite (TiO2–BiFeO3) nanoparticles for improved dye-contaminated wastewater treatment. The manufacturing and operational factors that affect membrane compatibility, nanoparticle dispersion, and overall performance were emphasized. Within a central composite design framework, response surface methodology (RSM) in conjunction with analysis of variance (ANOVA) was used to methodically assess the effects of important variables, such as operating pressure (100–300 kPa), Congo Red (CR) dye concentration (0.1–0.3 g/L), and nanoparticle loading (0–0.1 wt%). Strong prediction ability was shown by the constructed model, which also found ideal conditions at 132 kPa operating pressure and 0.06 wt percent nanoparticle loading. In these circumstances, the membrane obtained a 99.88% CR dye rejection and a permeate flux of 44 kg·m⁻²·h⁻¹ . These results demonstrate the considerable potential of PES/TiO2–BiFeO3 mixed matrix membranes for advanced dye wastewater treatment applications by confirming their markedly improved permeability and separation efficiency.
