| Tartalmi kivonat: | The purpose of this work was to investigate the potential of membrane ultrafiltration for the recovery of proteins from dairy effluents. Employing a 10 kDa tubular ceramic membrane in total recycle and batch modes, the effects of temperature, feed flow rate, and protein concentration in feed were evaluated by measuring permeate fiux-transmembrane pressure and permeate flux-time profiles, and total protein rejection coefficients. Results from these experiments have been used to analyze the technical viability of the recovery of dairy proteins by ultrafiltration. Last stage of ihe work consisted of a preliminary analysis of different phenomena limiting flux in this system. For this reason, previous experimental data were fitted with mathematical models proposed in bibliography by means of a computer tool of our own programming. Furthermore, a thermo-chemical washing method was successfully applied to clean tubular ceramic membranes previously fouled with dairy solutes. |
