The present manuscript explores a comprehensive study on effective parameters of a submerged photocatalytic membrane reactor (SPMR) comprising both membrane and photocatalytic parameters. For this propose, the response surface methodology (RSM) was applied and five effective parameters i.e. PVDF polymer concentration of the fabricated membrane (change of the membrane pore size), TiO₂ nanofiller amount in the matrix of membrane (for reducing fouling), aeration rate on membrane surface (for providing the required oxygen for photocatalytic reaction and also reducing the membrane fouling), reactor temperature and pH of the dye wastewater were used as input of the RSM. The outputs were flux, fouling reduction and dye removal percent of the membranes. UV/TiO₂/PVDF process was used for Rhodium B (RhB) dye degradation. The optimum conditions were PVDF concentration of 18 wt%, 10 wt% TiO₂ in membrane matrix, reactor temperature of 40 °C, pH = 5 and aeration rate of 1.6 L/min. After 320 minutes, the RhB dye degradation of 70% was obtained and remained constant for a long time in the continuous reactor. pH adjustment was the main effective parameter on membrane fouling reduction. Finally, the optimal conditions were applied for treatment of Eshtehard Industrial Park wastewater and pollutant removal of 60% was resulted for real wastewater.

本手稿探索了对同时包含膜和光催化参数的浸没式光催化膜反应器（SPMR）的有效参数的综合研究。对于此建议，应用了响应表面方法（RSM）并获得了五个有效参数，即所制备膜的PVDF聚合物浓度（膜孔径的变化），膜基质中的TiO ₂纳米填料量（用于减少结垢），曝气膜表面的反应速率（用于提供光催化反应所需的氧气并减少膜污染），反应器温度和染料废水的pH值用作RSM的输入。输出为膜的通量，结垢减少率和染料去除率。紫外线/ TiO ₂/ PVDF工艺用于铑B（RhB）染料降解。最佳条件为：PVDF浓度为18 wt％，膜基质中TiO ₂为10 wt％，反应器温度为40°C，pH = 5，充气速率为1.6 L / min。320分钟后，RhB染料降解达到70％，并在连续反应器中长时间保持恒定。pH调节是减少膜污染的主要有效参数。最后，将最佳条件应用于埃什特哈德工业园区废水的处理，对真实废水的去除率达到60％。
