Large quantities of produced water are generated during oil and gas exploration activities as for each barrel of oil, three barrels of produced water is generated. Due to their hydrophobic nature, conventional hydrophobic polymeric membranes struggle to effectively separate oil from produced water. In this work an innovative strategy is suggested by employing a hydrophilic/super-oleophobic nanocomposite to develop novel polymeric membranes able to effectively separate oil content from produced water without negatively affecting the other membrane properties such as the total flux and fouling. Graphene oxide-Chitosan-silicone oxide (GO-CH-SiO2) nanocomposite was synthesized by functionalizing graphene oxide (GO) with chitosan (CH) and silicon dioxide (SiO2). To improve the membrane flux, anti-fouling propensity and oil rejection, the synthesized nanocomposites were doped in the polysulfone membranes matrix. The effect GO-CH-SiO2 concentration, GO:CH ratio and GO-CH:SiO2 ratio on the performances of developed membranes were experimentally assessed and morphology of the synthesized membrane were investigated using appropriate characterization techniques. The experimental results showed that the membrane with GO:CH of 1:2 and GO-CH: SiO2 ratio of 1:6.5 showed the highest pure water permeation flux of 28.35 LMH/bar with a comparable flux recovery rate of 76% and oil rejection efficiency of 98.5%.
