Combination of Advanced Oxidation Processes and biological treatments for wastewater decontamination—A review
TLDR
The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation.About:
