Synergistic effects of natural biosurfactant and metal oxides modification on PVDF nanofiber filters for efficient microplastic and oil removal

Original language description

The removal of microplastics and oil from oil-water emulsions presents significant challenges in membrane technology due to issues with low permeability, rejection rates, and membrane fouling. This study focuses on enhancing nanofibrous composite membranes to effectively separate microplastic contaminants (0.5 µm) and oil-water emulsions in wastewater. Polyvinylidene fluoride (PVDF) polymeric nanofibers were produced using a needle-free electrospinning technique and attached to a nonwoven surface through lamination. The membranes were modified with alkaline treatment, biosurfactant (BS), TiO2, and CuO particles to prevent fouling and improve separation efficiency. The modified membranes demonstrated exceptional water permeability, with BS-modified membranes reaching above 9000 L m−2 h−1 bar−1 for microplastic separation. However, BS modifications led to reduced water permeability during oil-water emulsion treatment. TiO2 and CuO further enhanced permeability and reduced fouling. The TiO2-modified membranes exhibited superior performance in oil-water emulsion separation, maintaining high oil rejection rates (∼95 %) and antifouling properties. The maximum microplastic and oil rejection rates were of 99.99 % and 95.30 %, respectively. This study illustrates the successful modification of membrane surfaces to improve the separation of microplastics and oil-water emulsions, offering significant advancements in wastewater treatment technology.
