Treatment of Micro-Polluted Surface Water by the Nanomaterials Modified PVDF Ultrafiltration Membrane

Abstract:

The PVDF ultrafiltration membrane was modified by step in situ polymerization coupled with TiO₂-PANI membrane surface modifying. It has been prepared by different oxidants, such as ammonium persulfate (APS) and ferric chloride (FeCl₃). Meanwhile, application of the modified PVDF ultrafiltration membrane on treating micro-polluted surface water was studied. Turbidity removal efficiency, organic compounds and ammonia nitrogen (NH₃-N) were mainly concerned. The results show that the modified PVDF UF membranes can remove 95% turbidity, UV₂₅₄ higher than 50% which was increased greater than the original film. When FeCl₃ was taken as oxidant with 0.03mol/L, less by-product, NH₄⁺, was generated than APS. Thus, the ammonia nitrogen removal rate is as high as 85.2% and is 20% more than the original film.
