Web7. jan 2024 · Reverse Osmosis. Reverse Osmosis is the reversal of this natural phenomenon, by the application of external pressure on the solution that contains the higher concentration of dissolved ions, this forces water through the semi-permeable membrane in the opposite direction, leaving behind the dissolved ions and the suspended solids. WebThe UF permeate, containing about 0.1%–0.5% of proteins and 5% of lactose, was submitted to the NF process. At an operating pressure of 20 bar a concentrated solution containing higher than 25% of lactose was obtained. By selecting proper operating parameters (operating temperature of 30°C and VRF 5) the lactose yield was higher than 90%.
