In this thesis, the Photon Initiated Oxidation (PIOx) system was investigated for its possible use in the treatment of Endocrine Disrupting Compounds (EDCs). It was theorized that the unique design of the system, namely the multiple wavelengths of UV light and the micronfoam would improve removal rates of the test contaminant when compared to other systems. 17β-estradiol was chosen as the test contaminant due to the compounds known sensitivity to ozone exposure. Two methods of testing were used, the first to test an idealized homogenous concentration (method one) and the second to mimic the sudden influx of contaminant that would be common in a water and wastewater treatment environment (method two). Method one showed degradation to below level of detection within 15 minutes. Method two showed a reduction trend but with 60-80% eliminated by the end of 15 minutes. While the PIOx system did not perform above expectations, its simplicity and compact form-factor allows the system to be applicable in a significant number of situations where other AOPs would be too expensive or complex to implement. Continued research is required into the PIOx systems capabilities and its application to low budget and rural environments.
