Abstract :
Pulsed arc electrohydraulic discharge process (PAED) has been studied for the removal of some of organic pollutants. Firstly, the destruction of para-chlorophenol by PAED system was studied under some different experimental conditions (ionic strength, pH, conductivity and organic initial concentration) in a 5.6-L reactor with the following configuration: 2.9 kV of potential, 140 muF of capacitors. Secondly, the energy consumption for the degradation of 4-CP was estimated. From four initial concentrations of 4-CP, the energy consumption was found to be about 3.5 105 kJ/mol. A comparison between PEAD efficiency to convert 4-CP with UV-254 nm, O3 and O3/H2O2 systems is finally presented.
