System and method for advanced oxidation of treated sewage effluent

A method for post-treatment of treated sewage effluent, consisting of the steps of:

• exposing treated sewage effluent to ozone and hydrogen peroxide to oxidize contaminants therein to provide a first decontaminated treated sewage effluent;
• removing suspended particles from the first decontaminated treated sewage effluent, wherein the removal of particles consists of the steps of:
• coagulating remaining waste in the treated sewage effluent,
• flocculating the coagulated treated sewage effluent,
• holding the flocculated treated sewage effluent in a settling tank for sedimentation to occur, wherein the sedimentation occurs for at least 30 minutes,
• removing coarse suspended particles from the flocculated treated sewage effluent by a first filtration after sedimentation to provide a first filtered sewage effluent;
• and
• removing fine suspended particles from the first filtered treated sewage effluent by a ceramic or polymer ultrafiltration to provide a second filtered treated sewage effluent.
