Catalytic Ozonation of Phenol

open access: yesJournal of Korean Society of Environmental Engineers, 2011
Abstract : In this study AOPs of O 3 /UV radiation, O 3 /Mg(OH) 2 /UV radiation and O 3 /MgO/UV radiation system for phenol treatment in aqueous solution was performed in a laboratory scale circulating batch reacter. Flow rate of ozone 1.0 L/min, ozone concentrations 150 ± 10 mg/L was maintained constantly at the above-mentioned oxidation processes ...

Urban Wastewater Treatment by Catalytic Ozonation [PDF]

open access: yesOzone: Science & Engineering, 2015
This study focuses on the catalytic ozonation of organic matter recalcitrant to usual water treatment technologies. Experiments aimed to investigate the efficiency of the process TOCCATA®, which uses a granular catalyst coupled with ozonation. Comparison was made between single ozonation, single adsorption onto the catalyst and catalytic ozonation ...
