Ultrasonic Cavitation in Wastewater Treatment from Azo Dye Methyl Orange

Abstract

The work is devoted to the study of reagent treatment of methyl orange mono azo dye under the action of acoustic vibrations of the ultrasonic range. The positive effect of cavitation phenomena on the rate of mineralization of azo dye (13.4% increase) was compared with the reagent treatment of the solution without ultrasonic vibrations. On the basis of the analyzed information sources and experimental results, a schematic technological scheme of cavitation-reagent mineralization of methyl orange was developed, the main apparatus of which is a hydrodynamic jet cavitator (scaling for industry).
