Abstract

Membrane fouling is a major concern in microfiltration of metalworking fluids (MWFs). In this study two experiments were undertaken using a-alumina membranes in the microfiltration of a semi-synthetic MWF. The first experiment tested the effect that MWF concentration has on MWF flux. It was found that MWF concentrations between 1 % and 5% yielded similar steady-state fluxes after several days of processing. Membrane fouling occurred first by a deposited layer of MWF particles causing pore constriction followed by the formation of a porous cake layer of particles. The second experiment examined the effect of operational parameters on the formation of the cake layer. A 2 3 factorial experiment determined that increasing cross-flow velocity retards cake. formation and that transmembrane pressure only affects membrane flux in the presence of backpulsing.
