ultrasonic cavitation

The main methods for removal dyes from wastewater and the essence of advanced oxidation processes are considered. The advantages of using solid-phase oxidizing agents compared to liquid-phase oxidants are presented. The influence of the specific power (P/V) of ultrasonic cavitation treatment on the efficiency and intensity of dyes degradation using advanced oxidation processes based on simultaneously activated by ultrasonic cavitation and catalysts of solid-phase oxidizing agents is analyzed.

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.
