H. Carrere et al., Modelling the clarification of lactic acid fermentation broths by cross-flow microfiltration, J MEMBR SCI, 186(2), 2001, pp. 219-230
This work is focused on modelling microfiltration for clarifying fermentati
on broths for the production of lactic acid. The hydraulic resistance-in-se
ries model was used with membrane resistance, bacterial cell cake resistanc
e, adsorption resistance and solute concentration polarisation resistance.
Most of the model parameters were determined from independent experiments.
This model was applied for microfiltrations operated either under constant
transmembrane pressure or under constant permeate flux. Resistances due to
adsorption and to solute concentration polarisation dominated. Bacterial ca
ke resistance was found to be very low or equal to zero when microfiltratio
n was below the critical flux. (C) 2001 Elsevier Science B.V. All rights re
