Enhancement of microfiltration of yeast suspensions using gas sparging - effect of feed conditions

The experimental results show that (a) gas sparging can significantly increase the permeate flux of yeast microfiltration, (b) the feed pH has a profound effect on the permeate flux of yeast microfiltration, (c) the removal of extracellular substances results in much higher permeate flux (washed yeast) confirming that these were the major foulants and (d) the addition of inert particles can affect the microfiltration permeate flux and adding bentonite particles reduces the permeate flux of yeast microfiltration.
