ABSTRACT
Many dyeing, printing and textile industries dispose their wastewater directly to the stream without any proper treatment or with only some preliminary treatments. Various methodologies have been adopted for treating wastewater and these include biological treatment, oxidation, membrane filtration, sorption and coagulation/flocculation. Ultrasonic sound irradiation can effectively degrade different contaminants present in water because of the presence of localized high concentrations of oxidizing species. Ince and Tezcanli studied the degradation of reactive dye using United States. They observed that the rate of degradation increases by a combined process involving sonolysis and ozonation. Wu et al. reported the sonolytic degradation of cyclic hydrocarbons such as benzene, 1,3-cyclohexadiene, 1,4-cyclohexadiene and cyclohexene. The kinetics of several organic degradation products and chloride were also studied for the sonolysis of air- and argon-saturated solutions. A simple and an efficient sonochemical method was developed for the degradation of organic matter and ammonia nitrogen in azodicarbonamide wastewater.
