Abstract
A system and method for advanced oxidation (10) of treated sewage effluent provide additional treatment to treated sewage effluent (TSE) for reuse thereof. The method includes exposing TSE to ozone and hydrogen peroxide to oxidize contaminants; coagulating remaining waste in the TSE; flocculating the coagulated TSE; holding the flocculated treated sewage effluent in a settling tank for sedimentation; removing coarse suspended particles from the flocculated TSE by filtration after sedimentation; and removing fine suspended particles by ultrafiltration of the TSE after removing the coarse suspended particles. The system includes a chemical mixing tank (16); a homogenizing tank (22); an advanced oxidation process system (24); a rapid mixer; a flocculation tank (28); a sedimentation tank (32); a sand filter (34); and at least one ultrafiltration system (38), (36).
