Superior performance of catalytic ozonation on molecular-level transformation of effluent organic matter and self-cleaning property in catalytic ozonation membrane reactor

Catalytic ozonation membrane reactor (COMR) is one of the most promising technologies for municipal wastewater reclamation. Herein, we evaluated superior performance of catalytic ozonation in COMR through filtration of effluent organic matter (EfOM) using the origin and three catalytic membranes. We found that filtration primarily contributed to rejection of protein-like fluorescence enriched in relatively high-oxygen compounds (O/C >0.4) with high molecular weight and catalytic ozonation further removed humic-like materials and highly unsaturated, aromatic and reduced compounds (O/C
