Abstract: The ultrasound waves (20kHz to several hundred kHz) generated from the conversion of electric pulses by using a transducer can cause dramatic chemical and physical effects. Cavitating bubbles formed under ultrasonic irradiation produce high temperature and pressure conditions (up to 5,000K and 1,000 atm) inside the bubbles and as a consequence reactive oxygen species and many other reactive radicals are produced. The ultrasonic irradiation technique for cleaning polluted water has several merits over the other typical advanced oxidation technologies (AOTs) because this technique does not require chemical additives or catalystsand is independent of the color of the polluted water.
