This study evaluates the photodegradation efficiency of bisphenol A (BPA) in a visible light/TiO 2 system. TiO 2 was generated by the sol–gel method and polyethyleneglycol (PEG) was used as a modulator. The effects of the molecular weight of PEG, the addition percentage of PEG, the pH of the solution and the TiO 2 dose were determined. For a given percentage of PEG added, the...
Many ultrafiltration-related studies have emphasized fouling mechanisms, but few works have been done on resistance modeling. This study investigated the temporal variation of different resistances including membrane intrinsic resistance, fouling resistance, and concentration polarization resistance, based on a well established resistance--in-series model. The various resistances were determined at...
