In this work, we have tested a photocatalytic material consisting of a core of SiO2/Fe3O4
coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, a pilot plant of
45 L equipped with an Ultraviolet light (UVC) lamp was employed to study the degradation of a
model contaminant, enrofloxacin (ENR), as well as water disinfection (elimination of Escherichia coli
and Clostridium perfringens). The influence of different operational conditions was explored by
means of dye (rhodamine-B) decolorization rates, analyzing the effects of photocatalyst quantity,
pH and recirculation flow rates. The magnox/UVC process was also compared with other four
Advanced Oxidation Processes (AOPs): (i) UVC irradiation alone, (ii) hydrogen peroxide with UVC
(H2O2/UVC), (iii) Fenton, and (iv) photo-Fenton. Although UVC irradiation was efficient enough to
produce total water disinfection, only when employing the AOPs, significant degradations of ENR
were observed, with photo-Fenton being the most efficient process (total enrofloxacin removal in
5 min and c.a. 80% mineralization in 120 min, at pH0 2.8). However, Magnox/UVC has shown great
pollutant abatement effectiveness under neutral conditions, with the additional advantage of no acid
or H2O2 addition, as well as its plausible reuse and simple separation due to its magnetic properties. [-]
