The characteristic behaviour of the polysulfone (PSF), poly-(N-vinylpyrrolidone) (PVP), N-methyl-2-pyrrolidinone (NMP) ultrafiltration membrane casting solution system was investigated. Solutions containing different weight percentages of PSF and PVP were prepared. Zero-shear casting solution viscos

Micellar-enhanced ultrafiltration (MEUF) of phenol and a cationic surfactant, cetylpyridinium chloride (CPC), is studied using two polysulfone membranes of 5- and 50-kDa molecular weight cutoff (MWCO) and two ceramic membranes of 15- and 50-kDa MWCO. Filtrations are run under laminar cross-flow and
