Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 3,   Pages 362-367 doi: 10.1007/s11783-007-0062-9

Abstract: In this study, ultrasound was used to control the membrane fouling online in an anaerobic membrane bioreactorThe experimental results indicated that when the crossflow velocity was more than 1.0 m/s, membrane foulingWhen ultrasound was applied, an ultrasonic power range of 60–150 W was suitable for the membrane foulingThe experimental results showed that the membrane fouling was controlled so well that membrane filtrationresistance (Σ) could stay at 5 × 10 m for more than a week with the crossflow velocity of 0.75 m/s,
