The possibility of permeate flux enhancement based on the surface modification of a membrane was investigated. Crossflow microfiltration of a pure beer yeast suspension through smooth and stamped ceramic membranes was performed. The stamped membrane had a helical reversed thread to increase turbulence in the feed flow. Both membranes had an outer diameter of about 9 mm, the same zirkonia oxide active layer with a mean pore size of 0.23 pm. Membranes were produced by LMPM ENSCM. Fluxes of permeate were measured for different crossflow velocities and concentrations. A ceramic membrane with a helically stamped surface has several advantages compared with a smooth membrane: flux, as well as limiting flux, are higher at the same velocity of the feed, power consumption per unit volume of permeate is lower for the stamped membrane and increases with increasing crossflow velocity of the feed. Modelling of the flux decline indicates different mechanisms of fouling for smooth and stamped membranes.
