The high demand for oil results in an oilfield-produced water (OPW) production increment. The management of OPW presents a significant environmental and industrial challenge, attributed to its intricate composition, which encompasses hydrocarbons, suspended solids, and salts. Polyvinylidene fluoride (PVDF)/graphene oxide (GO)-based membranes, represent effective options for oil-water separation, attributed to their enhanced mechanical strength, hydrophilicity, and resistance to fouling. Maintaining the durability and performance of these membranes requires effective chemical cleaning strategies to mitigate fouling issues. This review discusses the fouling mechanism that takes place in OPW treatment, reviews chemical cleaning of the membranes utilized in OPW treatment, and compares the chemical cleanability of PVDF/GO-based membranes. The findings indicate that the chemical cleaning process of PVDF/GO-based membrane can be aligned with that of the PVDF membrane. The incorporation of GO in PVDF-based membranes can mitigate membrane fouling. The use of chemicals can be decreased as fouling decreases. This mitigates potential harm to the membrane during the chemical cleaning procedure, particularly when employing chemicals that are susceptible to resulting in damage. When the fouling is reduced, the chemicals used can be reduced, hence reducing the potential damage to the membrane during the chemical cleaning process, especially when using chemicals prone to causing damage. This study analyses recent developments and proposes future directions to optimize the cleaning process, enhancing the sustainability and operational efficiency of PVDF/GO-based membranes in OPW treatment applications.
