Modeling of catalytic ozonation process in a three-phase reactor
Journal of Environmental Science and Health, Part A, 2009 In this research, the main objective was to determine the flow characteristics of a three-phase reactor in order to use this knowledge in the modeling of catalytic ozonation of aqueous dye solutions. Therefore, the stimulus-response method was used in the tracer experiments; thus, the degree of liquid mixing in the reactor was estimated by means of ...

Urban Wastewater Treatment by Catalytic Ozonation [PDF]
Ozone: 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 ...
