Recent studies in environmental applications of ultrasoundA paper submitted to the Journal of Environmental Engineering and Science.

Abstract

As a young, new, and rapidly growing science, the applications of ultrasound in environmental technology hold a promising future. Compared with conventional methods, ultrasonication can bring several benefits such as environmentally friendly (no toxic chemicals are used or produced), low cost, and compact (allowing on-site treatment). Beside an overview on ultrasonic background, this paper summarizes main findings and innovations of recent studies that used ultrasound in environmental analysis, water and sludge treatment, soil and sediment remediation, and air purification.
