Flow field regulation and sediment particle flocculation mechanisms in ultrasound-assisted electrocoagulation intervention.

ABSTRACT: Ultrasound-assisted electrocoagulation (US-EC) shows promise in improving flocculation through cavitation and flow field regulation, yet the mechanisms of flow field evolution and particle size control under acoustic-electric coupling remain underexplored. In this study, an acoustic-electric coupling observation platform for suspended sediment flocculation was established. The motion response characteristics of gas-solid and mixed phases under the intervention of acoustic-electric coupling were observed by employing Particle Image Velocimetry (PIV). Then, the effects of different ultrasonic frequencies and current densities on flow field characteristics, particle size distribution, and flocculation behavior were systematically explored, and ultimately, the synergistic mechanism of US-EC in
