Fig. 1 shows the effect of microfiltration on permeate fluxes of UF for model whey solution.  It can be noticed that the permeate fluxes of MF whey are approximately double the whey feed fluxes. It is believed that microfiltration avoids contaminants deposited onto the UF membrane pores, which could reduces permeate flux.

The effect of microfiltration on permeate fluxes of UF for model whey solution is shown in Fig. 1, which shows that the permeation fluxes of MF whey are approximately double to that of the whey feed fluxes. The reduced permeation flux can be explianed according to the effect of  microfiltration by avoid contaminants deposited into the UF membrane pores.

The significant differences in the permeate fluxes between MF pre-treated whey feed and control were observed, which lasted at least for 90mins(Fig.1). One possible explanation of such low amount of permeate fluxes in  MF pre-treated whey feed solution is that microfiltration may try to prevent contaminants from migrating into the pores of UF membrane.
