Abstract This research emphasized the importance of removing organic pollutants from wastewater discharges. In this review, different advanced oxidation processes are discussed. A broad classification was used for treatment. An overview TiO2-based photocatalysis, Fenton process, and photocatalytic ozonation has been done. The mechanism methods studied. advantages limitations these also Various ...

The elimination of xylene was experimentally studied using advanced oxidation process in a two-step pilot plant photochemical unit with the use UV irradiation combined ozone (first step) and hydrogen peroxide solution (second step). influence initial concentration air flow rate investigated. A mathematical model first step applying UV/O3 treatment developed. Xylene conversion decreased increasi...

This Special Issue includes manuscripts on mechanistic understanding, development, and implementation of advanced oxidation processes (AOPs) for the removal contaminants emerging concern in water wastewater treatment. The main goal was successfully achieved under joint effort authors, anonymous reviewers, editorial managers. Totally, one review 15 research papers are included Issue. These mainl...

Heterogeneous catalytic ozonation (HCO) is a promising advanced oxidation process (AOP) that can effectively degrade recalcitrant organic pollutants; but formation of harmful byproducts should be carefully evaluated.
