Advanced oxidation technologies (AOTs) have emerged as innovative and effective methods for water and waste-water treatment. These techniques involve the generation of hydroxyl radicals (OH) to oxidize and degrade persistent organic pollutants and emerging contaminants, often rivaling the performance of established water treatment processes. The potential applications of AOTs for treating diverse source waters and oxidizing contaminants are extensive. In comparison with technologies like granular activated carbon and membranes, AOTs offer effective and cost-efficient treatment in three key areas: (1) micropollut-ant treatment, (2) addressing taste-and-odor compounds, and (3) treatment of recycled water. The advanced oxidation can serve as a final polishing stage for pre-treated effluents or can be employed as a primary or secondary treatment step to enhance subsequent biological processes and membrane separation.
