Abstract
Systems and methods for acoustically-enhanced membrane separation are described. The system may generally include a separation membrane and an acoustically-responsive structure positioned proximate the upstream side of the separation membrane. The system may further include a transducer for generating an acoustic field, wherein the acoustic field causes microstructures extending from the acoustically-responsive structure to oscillate and thereby create streaming effects in the region between the distal ends of the microstructures and the upstream side of the separation membrane. These streaming effects can prevent or remove separation membrane fouling, prevent the formation of cake layers on the separation membrane, and/or remove cake layer formed on a separation membrane.
