Abstract – Advanced oxidation processes (AOP), such as ozonation, photolysis, UV-H₂O₂, solar photo-Fenton, photocatalysis and photoelectrocatalysis have been demonstrated to be effective in the degradation of persistent pharmaceuticals residues in surface water, groundwater and wastewater. Radiation transport, fluid-dynamics and mass transport are all critical interlinked factors that govern the performance of chemical, photochemical and photoelectrochemical reactors. Through efficient reactor design, the radiation field in photoreactors can be optimized, the reactor fluid-dynamics can be matched to the radiation field to yield higher pharmaceuticals residues conversion, and the gas-liquid mass transfer in ozonation reactors can be intensified. In this presentation, the degradation of persistent pharmaceutical residues in water such as antidepressants, antibiotics, oestrogens, antiviral, antiretrovirals, antifungal and illicit drugs will be discussed in multi-scale photoreactors systems at both micro- and macro-scale such as multi-orifice oscillatory baffled column [1-2], fluoropolymer microcapillary array film photoreactors [3-5], pilot-scale solar fountain and compound parabolic collectors [6-8] and full-scale solar photo-Fenton raceway reactors [9]. The optimisation and intensification of pharmaceuticals removal in these and other AOP photoreactors will be examined.
