Implication

This analysis shows improved contaminant removal with ozone/biologically active filtration and UV/AOP, highlighting effective water quality solutions.

Key Points

Ozone/biologically active filtration achieved over 95% removal of five contaminants, enhancing treatment effectiveness.
Chemical contaminants were effectively degraded through UV/AOP, especially using hypochlorous acid compared to hydrogen peroxide.
The alternative method improved UV transmittance, aiding disinfection without exceeding regulated by-product limits.
Further studies are needed to explore the complete efficacy of O3/BAF on all contaminant types in potable reuse systems.
