Ultrafiltration (UF) has been used in the dairy industry to produce whey-protein concentrates, because this technology allows the selective concentration of the proteins in relation to the other components. The lactose and mineral-rich solution that is removed via passing the membrane leave the module as permeate. The process was conducted using membrane molar weight cut-off of 10 kDa at transmembrane pressures (200 kPa), temperatures (50 °C), and feed flow rates (840 L/h). The process shows that the permeate flux significantly decreased with time and it will significantly affect the processing. Identify the possible resistance that occurred in the UF membrane during this process. Illustrate and describe the mechanism of the membrane.

Ultrafiltration (UF) has been used in the dairy industry to produce whey-protein
concentrates, because this technology allows the selective concentration of the proteins
in relation to the other components. The lactose and mineral-rich solution that is removed
via passing the membrane leave the module as permeate. The process was conducted
using membrane molar weight cut-off of 10 kDa at transmembrane pressures (200 kPa),
temperatures (50 °C), and feed flow rates (840 L/h). The process shows that the permeate
flux significantly decreased with time and it will significantly affect the processing. Identify
the possible resistance that occurred in the UF membrane during this process. Illustrate
