A method to clean a treatment water containing brackish or sea water and further containing a veterinary product for aquatic animals, the method comprising the steps of:

Method and device to clean a treatment water containing a veterinary product for aquatic animals

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.

Ozone oxidation process for treatment of water containing azoles and azole-type compounds

The invention is directed to systems and methods of biological and chemical treatment of wastewater comprising organic nitrogen compounds. Systems may include: an aerobic reactor, a first separation module for separating liquid and solid components of the wastewater; an oxidation module for removing organic materials from the wastewater; and a post-anoxic reactor for denitrifying at least a portion of the wastewater. Systems may include a second separation module and various feedback recycle lines between the components. Methods may include: degrading by the aerobic reactor more than 95% of organic compounds to ammonia, oxidizing by the oxidation module at least a portion of the ammonia to nitrates, and degrading by the post-anoxic reactor at least a portion of the nitrates to nitrogen gas and water. Systems and methods may reduce total organic carbon of the wastewater by more than 90%, and total nitrogen of the wastewater by more than 90%.
