Advanced oxidation processes (AOPs) have proven to be among the most effective techniques for removing OMPs from water samples. However, for economic feasibility, the source of light is a critical aspect of AOPs. The objective of the proposed project is to develop and optimize innovative technology based on UV-LED AOP for the economically viable treatment of wastewaters containing OMPs with the goal to maximize the effectiveness regarding OMPs removal, toxicity and biodegradability of treated water. The research work will be focused on studying the applicability of different UV-LED AOPs for the degradation of pharmaceuticals in simulated and real wastewater. The following AOPs will be investigated: photochemical (UV-C with H2O2) and photocatalytic (UV-C, UV-A) with TiO2 with/without addition of H2O2. Degradation of targeted OMPs and formation of their transformation products will be monitored by LC coupled to high resolution mass spectrometry (HRMS) and by toxicity on Vibrio fischeri and Daphnia magna. An evaluation of potential reactor geometries and positioning of LEDs inside the photoreactor will be conducted as well as designing treatment applications that adjust to the unique features of LEDs compared to other light sources.
