Abstract: In this study, Polyvinylidene Fluoride (PVDF) nanocomposite membrane consisting of electrospun titanium dioxide (TiO2) nanofibers (PVDF/e-TiO2) was prepared by hot pressing the as-spun TiO2 nanofibers onto PVDF flat sheet membrane. The hot press technique was carried out by applying the operating pressure at 1 bar, 1.5 bar and 2 bar for 30 seconds. The nanocomposite membrane was characterized by Scanning Electron Microscope (SEM) spectroscopy. The SEM images and analysis shows good adhesion and dispersion of TiO2 nanofibers in PVDF membrane. Based on the results, it can be concluded that a fine-tuning on the optimization study of the membrane hydrophilicity by several approaches such as pure water flux, glucose rejection and contact angle is desirable in order to ensure the developed PVDF/e-TiO2 membranes can be simultaneously efficiently functioned by means of filtration applications. Membrane successfully done glucose rejection and then COD analysis is carried out with higher efficiency. As the pressure increases the chemical oxygen demand (COD) increases because dissolved oxygen is removed in retentate side together with glucose.
