Emerging investigators series: prediction of trace organic contaminant abatement with UV/H2O2: development and validation of semi-empirical models for municipal wastewater effluents

Recent evaluations of potable reuse treatment trains suggest that the use of UV and UV/H2O2 may become increasingly common, particularly in systems employing ozone and/or biofiltration. This study provides a summary of photolysis rate constants and (OH)-O-center dot rate constants and demonstrates the applicability of semi-empirical relationships predicting (OH)-O-center dot exposure and trace organic contaminant (TOrC) abatement with UV/H2O2 in matrices with low UV transmittance (e.g.,
