and water + isopropyl alcohol (IPA) (80/20 v %) were used as solvent and coagulant, respectively. The AFM image shows that the membrane with high porosity in surface is formed at low concentration of PVP (2 wt %) in the casting solution. Also, the pure water flux, milk water permeation and protein rejection measurements indicate that the membrane performance improves with addition of 2 wt% of PVP in the castingsolution.
