In this experimental work, the energy demand at different pressures (0,2 MPa and 0,5 MPa), the temperature (20 °C and 50 °C) and the cow’s milk fat (0,1 % and 3,6 %) during ultrafiltration by membranes with different membranes - 10 kDa and 25 kDa, was investigated. The lower values of energy demand were established at lower pressure, fat and higher temperature. The greatest influence had the pressure for two membranes investigated, and the lowest - the fats for membrane 10 kDa and the temperature for membrane 25 kDa, respectively. Membrane 10 kDa had higher energy demand than another membrane.
