Application of the resistances in series model in ultrafiltration

This study deals with a subject that has recently been developed in our laboratory and whose aim is to reduce fouling of tangential membranes. In the work reported here, we show that, thanks to the resistance model, the effects of instabilities generated by a double-phase gas-liquid flow in the presence of a turbulence promoter lead to a more efficient hydrodynamics in terms of reducing deposited material on the membrane surface. The use of such a process to filtrate sodium alginate leads to very encouraging results allowing flux improvements by a factor of 2.3.
