• Post‐treatment was carried out to eliminate the colour and COD of treated combined industrial effluent. Ozonation at a dose of 300 mg/h for 10 min resulted in 100% colour and 96% COD removal at pH 8 and temperature 25 °C. The application of UV/H2O2 resulted in 91% colour and 82% COD removal. 79% colour and 60% COD removal was obtained with the Fenton process after 60‐min treatment in the presence of 170 mg/l H2O2, while the photo‐Fenton process showed an almost complete elimination of both parameters. Electrical energy consumption showed that the photo‐Fenton resulted in the highest removal efficiency with 95% removal in terms of colour and COD abatement rates. The electrical energy requirements of the tested processes followed the increasing order UV/Fe/H2O2 < O3 < UV/H2O2 < UV.
