5. To propose effective processing technology based on the characteristics of real wastewater and quality requirements of treated water.

1. Advanced Oxidation Processes for Water and Wastewater Treatment, Advances in chemical water and wastewater treatment led to a range of processes termed advanced oxidation processes, AOPs. AOPs have shown great potential in treating pollutants at low and high concentrations and have found diverse application, Simon Parsons Ed., IWA Publishing, 2004.
2. Chemical Degradation methods for Wastes and Pollutants, Environmental and Industrial Applications, Chemical methods, particularly AOPs, can be advantageous over biological methods, because they are often faster, can treat highly contaminated systems and are less sensitive to ambient conditions., Matthew A. Tarr, Ed., Marcel Dekker, Inc., 2003.
3. Advanced oxidation processes for water treatment, fundamentals and applications, AOPs rely on the in situ generation of powerful oxidizing radical species and on their high reactivity toward a range of micropollutants. AOPs are implemented fir surface water, groundwater and municipal wastewater treatment and water recycling., Michaela L. Stefan, Ed., IWA publishing, 2018.
