Fabricating electrospun nanofibres has drawn more attention due to the rapid advancement of nanotechnology. Electrospun nanofibre membranes are attractive materials in various applications due to their distinctive characteristics, which include interconnected pore structure, high porosity (90%), tribological and mechanical properties, specific surface area, and remarkable functional capabilities. The electrospun fibre membrane addresses the drawbacks of existing approaches' poor efficiency and high energy requirement, particularly in wastewater treatment. In this thesis, non- woven nanofibre membrane containing nanoparticle anti-fouling was created using electrospinning technology for filtering emulsified oil from water. A quick and reliable way to make polymeric nanofibres of different diameters and morphologies is by electrospinning. A nonwoven fibrous membrane is produced by electrospinning, which involves charging a viscoelastic fluid to cause a liquid jet to be propelled from a needle and gathered on a drum collector. In the first part of this work, the polymer hydrophilic Polyacrylonitrile (PAN) polymer was dissolved in Dimethylformamide (DMF) solvent to an initial solution of 10% PAN/DMF concentration. Then different concentrations of silica nanoparticles (6, 8, 10 wt %) were added. Second, the polymer hydrophobic Polyvinylidene difluoride (PVDF) polymer was dissolved in dimethylformamide (DMF) solvent to an initial 10% PVDF/DMF concentration solution. Then different concentrations of silica nanoparticles (6, 8, 10 wt %) were added. Under constant conditions of operation, fabricated nanofibre membranes have been employed to filter out emulsified oil via a cross-flow filtering system. Throughout the filtration experiment, the permeate flow and the percentage of oil rejection were used to gauge how well the manufactured membrane performed. As a result of the built-up fouling on the membrane surface, the filtration findings revealed an apparent reduction in the permeate flows over time. Each fabricated nonwoven nanofibre membrane's surface was examined using field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR).
