Abstract: Combined effects of working pressure, temperature and fat content on the flux during ultrafiltration of cow’s milk with a polyacrylonitrile membrane UF10-PAN through full factorial experimental design were studied. Multi-factorial mathematical model for the influence of working pressure, temperature and fat content of milk on the flux was created. The model and response surfaces show that the highest value of flux is obtained at high level of the working pressure and temperature, and low level of the fat content of milk.
