The dynamic ultrafiltration of anionic surfactant solution, sodium dodecyl benzene sulfonate (SDBS), using a rotating disk system with hydrophilic polyethersulfone (PES) membranes (MWCO 10 kDa) was studied in this paper. The effects of mean transmembrane pressure (TMP) and disk rotating speed on the

Ultrafiltration of UHT skimmed milk has been carried out using a smooth disk and a disk equipped with 6-mm-high vanes rotating at high angular velocity T near a circular 50 kD membrane. Permeate turbidity was less than 2 NTU confirming complete casein micelles retention. The addition of vanes to the
