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

The aim of this work is to characterize more accurately, through experimental or theoretical approaches, the hydrodynamics of three particular systems usually used for flux enhancement: shear-enhanced filtration with a vibrating membrane module, gas/liquid two-phase flows and Dean vortices. The corr

A vibratory shear-enhanced filtration system (VSEP) was used for the separation of casein micelles from whey proteins of skim milk reconstituted from low heat milk powder, which has a similar protein content as fresh milk. This paper compares the performances of microfiltration (MF) with a 0.1 µm po

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
