Studies Of Antifouling Properties On Ultrafiltration Membrane For Oily Wastewater
Organic-inorganic composite membranes were synthesized through phase inversion technique with nano-sized particles such as zinc oxide (ZnO), calcium carbonate (CaCO3) or titanium oxide (TiO2) uniformly dispersed in the polyacrylonitrile (PAN) solution. The effect of nanoparticles and type of nanopar...
