description The present invention is generally directed to the use of an ozone oxidation process to remove azoles and azole-type compounds from wastewater. Specifically, the present invention is directed to a chemical treatment system for wastewater, including: an oxidation module receiving wastewater input and outputting an effluent; wherein the oxidation module removes azole-type compounds from the wastewater; and wherein the effluent has a reduction in azole-type compounds greater than ninety percent (90%). In accordance with some embodiments, the present invention provides an oxidation module receiving as inputs: wastewater received from a chemical mechanical polishing process and ozone gas received from an ozone generator; the oxidation module outputting an effluent; wherein the oxidation module removes azole-type compounds from the input wastewater; wherein the effluent has a reduction in azole-type compounds greater than ninety percent (90%); and wherein the oxidation module does not require ferrous treatment or solid-liquid separation before treatment.
