Different types of advanced oxidation processes and their combinations such as O₃/H₂O₂/UV, O₃/Fenton/UV, O₃/TiO₂/UV, Fenton/H₂O₂/UV, Fenton/TiO₂/UV, TiO₂/H₂O₂/UV, TiO₂/H₂O₂/O₃/UV, TiO₂/O₃/Fenton/UV, TiO₂/H₂O₂/Fenton/UV and O₃/H₂O₂/Fenton/UV were studied for the treatment of undiluted red wastewater from Z113 Factory. The treatment efficiency was evaluated by analyzing chemical oxygen demand (COD) reduction, % degradation of α-TNT, 2,4-DNT, 2,6-DNT, 2,4-DNT-3-SO₃Na and 2,4-DNT-5-SO₃Na. Among studied processes Fenton/TiO₂/O₃/UV was the most effective technology to treat red wastewater. It allows to reduce > 99% of COD, α-TNT, 2,4-DNT, 2,6-DNT, 2,4-DNT-3-SO₃Na and 2,4-DNT-5-SO₃Na after 30h of treatment with optimum operating conditions: rotation speed of 600 rpm, pH of 4 and temperature of 40^oC. According to the chromatograms obtained by gas chromatograph/mass spectrometer (GC/MS), intermediates of the decomposition of pollutants in red wastewater were identified. GC/MS, HPLC, UV-vis and Bacterial Toxicity test were used to assess effluent quality changes before and after treatment. By economic analysis, the studied process had the potential to apply in practice to treat real wastewater at the Z113 Factory.
