Comparison of three different systems used for flux enhancement: application to crossflow filtration of yeast suspensions

摘要

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 correlation between local hydrodynamics and permeate flux obtained during crossflow filtration of a yeast suspension under different operating conditions confirmed the importance of the wall shear stress in these three systems.
