Over the past few decades, pesticide use in agriculture has skyrocketed. Pesticides are pollutants found in water sources that threaten both human health and the environment and cannot be properly handled using traditional wastewater treatment methods. In the current study, the extent of COD reduction from ozonation, ultrasound, and the combination of both methods used to study flonicamid decay in aqueous solutions was examined. The degradation was examined at optimal conditions of an ultrasound power of 90 W, a pH value of 2.0, a concentration of 20 ppm, an H2O2 loading of 1200 ppm, and a CuO loading of 0.5 g/l. When the US was used in conjunction with multiple approaches, COD was reduced to greater degrees than when the US was used alone. Ozone addition produces better ultrasound findings than simple ozonation. The largest COD reduction compared to other single systems is 92% when US + O3 + H2O2 + CuO are operating together. Overall, it has been proven with clarity that the operation of ultrasound with ozonation and catalysts such as H2O2 and CuO results in the greatest COD reduction.
