Pilot scale continuous reactor for water treatment by electrochemical advanced oxidation processes: Development of a new hydrodynamic/reactive combined model

Abstract The development of continuous flow electrochemical reactors is required to overcome the limitations conventional batch for treatment large flows effluents. Therefore, objective this study was develop and characterize a new pilot-scale reactor using BDD anode carbon felt cathode operating in mode. First, “Design Experiment” analysis performed order identify most critical parameters percentage mineralization 29.8 mg L−1 hydrochlorothiazide (HCT) solution. liquid rate has been identified as parameter together with configuration (number electrodes, distance between electrodes). Moreover designed able reach very high (97%) mean residence time 83 min. To better understand important role configuration, hydrodynamic then performed. “Residence Time Distribution” curves were obtained fitted well continuous-stirred tank series dead zones (CSTR-DZ) model. 28-electrodes had lower volume fraction whatever applied. By increasing behavior tends more plug reactor. Finally, mathematical model HCT solution proposed by combining kinetic CSTR-DZ This compared experimental data capture trends. approach opens up interesting perspectives successful scale-up reactors.
