How are low HRTs connected with the increase of EPS (and consequently membrane fouling rate) in MBRs? What's the chemistry behind this?

It has been observed that low HRTs promote membrane fouling in MBRs, due to the increase in bound or soluble EPS.

How can non-Newtonian (pseudoplastic) nature of liquid phase account for the decrease of void fraction in an upward co-current bubbly flow?

Maybe via the formation of larger bubbles which have higher rising velocity and result in the decrease of the respective residence time? If so, why shear-thinning behavior promotes the formation...
