Abstract: The membrane produced was imposed by two rheological factors, which applied with different coagulation bath temperature at 10 °C, 30 °C, and 50 °C and different forced convection resident time which was at 10 s, 15 s, and 20 s. Tho objective of this study is to investigate the effect of those rheological factors to the steric and charges on the separation performance and fine structural details of UF membranes. By using the same composition, an uncertainty imposed by the membrane material upon separation performances can be eliminated. The membrane is fabricated using a ternary dope formulation of 14.4% Polysulfon_e (PSF), 81.6% N-methyl-2 pyrrolidone (NMP), and 4% water by a dry/wet phase inversion process using an electrically controlled flat sheet membrane casting machine.
