Micropollutant degradation in water by photochemical processes

The increasing legislation pressure, risks associated with micropollutants, and the insufficient efficacy of conventional WWTPs on their removal have formed a joint driving force that is boosting studies on more efficient treatment technology. The general objective of this thesis is to contribute to a better understanding and further development of photochemical treatment processes for micropollutant removal from aqueous streams. Emphasis of this thesis is given to two topics: (1) Further development of UV/TiO2 technique by application of TNA as immobilized catalyst; (2) Development of alternative photochemical water treatment technique for micropollutant removal from wastewater. This thesis demonstrates that: (1) TiO2 nanotube array is a promising immobilized photocatalyst for the removal of micropollutants; (2) Red light induced methylene blue photosensitization provides an efficient process for micropollutants removal.
