In this study the process of tannery wastewater treatment by electrocoagulation and coagulation with FeCl₃ followed by advanced oxidation processes (Fenton reaction, O₃/OH⁻ O₃/H₂O₂, H₂O₂ /UV) was investigated. Electrocoagulation resulted in a slightly better purification effect than coagulation. The purification effect obtained by AOPs decreased in the order: Fenton reaction
