The present study presents the sono-degradation petroleum refinery effluent and the influence of addition activated carbon and hydrogen peroxide on sonolysis. The sonolytic degradation was analyzed for the reduction in % COD of the effluent and the results showed that the combination of activated carbon and hydrogen peroxide gave better results. The effect of key operating parameters, such as sonication time and pH on % COD reduction were studied. Experiments were carried out at initial concentrations of activated carbon (0.5, 1, 1.5 and 2 gm) and activated carbon (2 gm) with hydrogen peroxide (50,100,150 and 200 mg/l) on sonochemical degradation of effluent at pH 10. This study showed that % COD remaining was found to be found that the activated carbon at 2 grams a better read, therefore, adopted with the added along with 50,100,150 and 200 mg/l hydrogen peroxide respectively. Degradation was found to increase with increasing sonication time. In addition, as the concentration is increased. At the end of 90 min of sonication, the % COD remaining was increases when the recycling of activated carbon increases.
