Synergistic Effect of Alternating Current-Based Electric and Acoustic Fields on Flux Recovery in Crossflow Microfiltration of Synthetic Wastewater

•A new electro-acoustofiltration device has been developed for simultaneous application of alternating current electric field and acoustic field for specific flux recovery.•Specific flux recovery in the presence of both fields is greater than numerical sum of fluxes (i.e., 1 + 1 > 2) due to AC electric field alone or acoustic field alone.•AC electric field and acoustic field have critical fields beyond which improvement in specific flux or fouling mitigation are minimal.•Specific flux recovery during simultaneous application of electric and acoustic fields depends on foulant type and composition, feedwater pH, and electric field and acoustic field parameters.
