Abstract:
   In this study, A PVDF membrane modules antifreeze was developed for protecting PVDF hollow fiber membrane from freezing and suffering performance under lower temperature. The effect of lower environmental temperature on anti-freezing properties of membrane modules was investigated in terms of its flux, tensile property, membrane hydrophily and Rejection ration. The experiments demonstrated that PVDF membrane modules can be kept under lower temperature by using this kind of membrane modules antifreeze, and the performance of membrane modules was not be affected.
