摘要

Industrial wastewater from oil refining processes poses significant environmental challenges due to the high concentration of petroleum hydrocarbons and increased chemical oxygen demand (COD), where conventional treatment methods fail due to severe membrane fouling in treatment systems. This study introduces a novel and stable green catalyst (GC) derived from calcium oxide (CaO) prepared from tomato sepal biomass, which is integrated as an efficient visible light photocatalyst with a polyacrylonitrile (PAN) membrane in a photocatalytic membrane reactor (PMR). The main objective was to optimize the PMR to maximize oil and COD removal while minimizing permeate flux (PF) reduction using synthetic wastewater simulated from industrial petroleum effluents. For this purpose, PAN membrane was fabricated via phase inversion and both GC and PAN were characterized using several techniques. Performance evaluation was performed under visible LED light irradiation with 14 W intensity, neutral pH and flow rate of 0.6 L/min, at membrane pressure of 2 bar, with different parameters through central composite design (CCD) in response surface methodology (RSM). The results of the experiments showed the outstanding performance of the PMR membrane with a one-hour treatment, which produced a wastewater flux of 74.34 L/m2h. At a concentration of 100 ppm, the oil and COD removal efficiencies were determined to be 99.20% and 97.15%, respectively. In addition, the PAN membrane showed remarkable self-cleaning performance, achieving a flux recovery ratio (FRR) of 96.24% when operating with industrial wastewater. The results showed the high potential of the PMR system in advancing industrial wastewater treatment by significantly reducing membrane fouling and increasing effluent quality, and achieving compliance with World Health Organization (WHO) standards through residual oil and COD concentrations of 5 and 100 ppm, respectively.
