| Abstract: | The experimental methods of ultrasound (US) enhancing ultrafiltration (UF), the influence of US irradiation on the structure of UF membranes and the efficiency of enhancement of cleaning of the UF membranes by US are reviewed. The mechanism of US enhancing UF is also outlined and It is believed that acoustic streaming and acoustic cavitation are key factors that influence the UF efficiency. |
