In this study, polyethersulfone membranes were prepared via immersion precipitation from quaternary systems containing N, N-dimethylacetamide (DMAc) as solvent, polyvinylpyrrolidone (PVP) and acetic acid as additives. The morphology and performance of the prepared membranes were investigated by Scanning Electron Microscopy (SEM) and separation experiments using milk as the feed. Acetic acid caused an increment in the flux at high polymer concentration (16 wt%) and a decline in the flux at low polymer concentration (10 and 13 wt%).
