EN Investigations were performed on tannery wastewater, previously coagulated with FeCl3. An electrolyzer was equipped with two graphite cathodes and Ti/SnO2/PdO2/RuO2 anode, divided by the diaphragm made of asbestos fibre. The current density was: cathodic 2.0 A/dm2 and anodic 2.1 A/dm2. After 55 min of the process the catholyte was transferred into the anodic space and the process was continued. After 55 min of electro-Fenton process, the COD was reduced by 52.0% (current efficiency of COD removal was 10.6%). Electrooxidation continued by the anodic process resulted in elimination of ammonia in 55 min and a total reduction of COD by 72.9%. The coupled process d could be considered a simulation of the combined process under flow conditions. The effect of this process was compared to that of a two-steps process: Fenton process followed by indirect anodic oxidation.
