Abstract
In this study, to research effect of coagulation bath and composition of dope solution, polysulfone flat sheet membrane was fabricated by phase inversion method. PEG and PVP were used as additive. Concentration of polymer and additive, composition of coagulation bath was controlled to prepare flat sheet membrane. And then the morphology and water flux of prepared membrane were measured by FE-SEM and water flux testing apparatus. The highest value of water flux was measured at the membrane prepared under a 15 wt% PSF, 25 wt% PEG conditions, and water as coagulation bath. The pure water flux of the membrane composed of PSf/PEG was drastically decreased with increasing amount of DMAc. We confirmed that change of amount in additive and composition in coagulation bath influence the morphology and water flux performance of the membrane.
