Preparation and Characterization of the PSF hollow fiber ultrafiltration support membrane

The hollow fiber ultrafiltration membrane is not only widely applied in industry field such as water treatment,it is but also abroad applied in preparation study of nanofiltration membrane and reverse osmosis membrane as support membrane. The PSF hollow fiber UF support membrane was preparation by dry-jet wet spinning,and the effects of concentraion of every component and spinning technology parameters on membrane performance were studied systematically. The results show that its pure water flux decreases a...
