Abstract:
The effect of colloidal interactions between casein micelles on the flux of a tubular ceramic membrane at cross-flow microfiltration (MF) of skim milk was studied. Filtration experiments were performed at a pH range of 6.8--5.9. Compared to filtration of milk at its native pH (6.8), the flux was reduced and membranefouling proceeded fasterwhenacidified milk was filtered. To explain the observed flux behavior, a new interaction model for casein micelles was developed, which incorporates on the ba...     »
