Catalytic Ozonation of Phenol

Journal 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 ...

Catalytic ozonation for removal of antibiotic oxy-tetracycline using zinc oxide nanoparticles

Applied Water Science, 2021
The traditional wastewater treatment plants are mostly not designed to deal with polar micropollutants such as pharmaceuticals. Therefore, antibiotics must be completely removed before their emission to ecosystems. Catalytic ozonation is used to increase
