Polysulfone (PS) and polyethersulfone (PES) ultrafiltration membranes were manufactured from a casting solution of the polymer, polyvinylpyrrolidone (PVP) in various solvents [ N , N ‐dimethylacetamide (DMAc), N , N ‐dimethylformamide (DMF) and 1‐methyl‐2‐pyrrolidone (NMP)] by immersing the prepared films in different non‐solvents [water, 2‐butanol, mixture of water and 2‐butanol, mixture of water and 2‐propanol (IPA) and mixture of water and 1‐butanol]. The influences of various solvents and non‐solvents on morphology and performance of the prepared membranes were analyzed by scanning electron microscopy (SEM) and separation experiments using milk as the feed.
