                    In this study, a polyvinylidene  fluoride (PVDF) ultrafiltration (UF/MF)
                    membrane  was  modified by  dispersing  nano-sized Silver  (Ag)  particles  in  a
                    PVDF solution. PVDF micro fibrous membranes were fabricated by
                    Electrospinning method. Nonwoven fabric was used as the support layer. This
                    study investigates the effect of Ag nanoparticles on antibacterial properties of the
                    membrane,  Effect  of Electrospinning parameters on membrane permeability.
                    The experimental result indicates that the addition of Ag nanoparticles increased
                    the  antibacterial properties of the  micro-fibrous membrane in addition to
                    increasing of  the  hydrophilicity.  PVDF  membrane  fouling  was  reduced  by
                    changing the membrane surface from hydrophobic to hydrophilic after Ag
                    particles addition.
