Summary: Solar driven advanced oxidation processes (S-AOPs) have been successfully studied as tertiary and quaternary treatment of urban wastewater. However, their application has been hindered by the lack of comparison data with consolidated technologies and evaluation of environmental impact. This study compared the environmental impact of a new S-AOP called sequential treatment (ST) with sunlight/H2O2 and solar photo-Fenton (SPF) to pilot scale ozonation (O-3) treatment through Life Cycle Assessment (LCA). The results showed that ST had a better overall environmental performance compared to O-3, making it a more sustainable solution for small urban wastewater treatment plants.
