Ultrasonic Decomposition of Organic Compounds in Wastewater

Abstract

The simplicity in design and use by small-scale in ultrasonic presented a chemical device for treatment of contaminated water. The environmental problem in the petrochemical fields are wastewater and organic pollutants. The effectiveness of ultrasound reactor in decomposition of organic pollutants in aqueous media was studied. Decomposition rate of organic compounds affected by factors such as the ultrasonic power, time, concentration, pH and temperature. Decomposition degree of benzoic acid increased with increasing ultrasonic power. It was observed that H₂O₂ has negative contribution on the decomposition of benzoic acid.
