This treatability study evaluated the overall effectiveness of advanced oxidation processes (AOPs) to treat membrane concentrates containing the pesticides bromoxynil and trifluralin. The results of study indicate that high levels of pesticide degradation were achieved using ozone (O3) plus hydrogen peroxide (H2O2) for all concentrate matrices. However, the toxicity of the samples during the O3/H2O2 process was higher than that obtained during ultraviolet (UV) light combined with H2O2. Low levels of pesticide oxidation were observed in experiments using a mixture of pesticides during all treatment options.
