MECHANICAL PROPERTIES OF POLYSULFONE-ZnO NANOCOMPOSITE MEMBRANE

Large quantities of wastewater are generated by the petroleum refining process. Micron-scale emulsion droplets and submicron difficult to remove from oil-refined wastewater, addressing these issues has been a major challenge for researchers. Membrane technology is widely used in water treatment because it very selective effective filtration his research focuses on oil refinery using polysulfone membrane (PSF)-nano-ZnO with addition polyethylene glycol (PEG). This aims determine PEG ratio that produces optimum PSF-ZnO terms mechanical properties, including thickness, tensile strength, molecular weight cut-off (MWCO) value. The membranes clearance were obtained at 3% thickness 0.0077 mm, Young's modulus 8800 N/m2, Morphological analysis was performed SEM (Scanning Electron Microscopy) method which had highest lowest permeability values.. best MWCO value achieved 19% PSF-nano-ZnO 1% wt 5 minutes UV irradiation. shows composite affects pore openings. formed variations concentrations affecting membrane. Higher make thicker, resulting higher Young’s modulus.
