'Abstract The natural environment, as well as water resources on the earth's surface are constantly under pressure from the ever increasing human activities due to globalization. Focusing on water pollution through natural and anthropogenic activities, water pollution has become a global problem causing adverse effects on both humans and the ecosystem both short and long term. The advancement in technology has given rise to analytical capabilities that have been able to trace these activities and have been noted to be emerging in the form of harmful organic pollutants resistant to natural degradations and biological treatment. This thesis focuses on experimental research on the use of Ozonation and Catalytic Ozonation for the degradation of phenol in water. Making good use of these processes to treat wastewater and polluted groundwater, it is essential to prevent the discharge of pollutants into natural bodies, secure access to good drinking water as well as public health. AOPs are a group of environmental technologies used to treat water, soil and air and when substantial quantity of individual or mixtures of organic pollutants get in contact with surface water through direct and indirect sources, they affect the quality of these water bodies. Therefore, APOs are used because, they demonstrate powerful techniques for the degradation of a wide range of toxic and refractory organic pollutants in different types of polluted water. The thesis has been carried out with the aim of degrading phenol using AOPs and possibly minimizing unwanted side reactions and the experimental analysis revealed that phenol actually degraded but under controlled conditions. The observations however, supports the theoretical suggestions to some extent and experimentally proved that catalytic ozonation works better with the degradation than just ozonation of phenol, considering catalytic ozonation achieved 97% removal efficiency after 1 minute and ozonation achieved just 29.6% removal efficiency after 1 minute. Catalytic ozonation as a technique for the removal of refractory organic pollutants in advanced water treatment, doubtlessly possesses a promising potential for the treatment of industrial effluents, but efforts are still being made to fully understand the byproducts formed and the consequences that will follow.
