Abstract In the present study a mathematical model has been applied to interpret permeate flux decay in the process of concentrating skim milk by ultrafiltration (UF) using a commercial membrane module. The effects of operational variables, such as temperature and transmembrane pressure, on membrane fouling have been studied using technical parameters. An energy analysis has demonstrated that the thermal process, and not the mechanical energy needed for fluid pumping, holds the main demand of energy consumption. In addition, achievement of higher volume of permeates by incrementing transmembrane pressure and not temperature, was assessed. The applied mathematical analysis led to evaluate engineering aspects of skim milk ultrafiltration regarding design and operation with optimal efficiency.
