This study evaluates the effectiveness of Fenton'soxidation (FO) process and ozone (O3) oxidation compared with a coagulation–flocculation (CF) process to remove effluent toxicity as well as colour and COD from a textile industry wastewater. Daphnia magna was used to test acutetoxicity in raw and pre-treated wastewater. The operational parameters for each process were determined on the basis of complete toxicityremoval. The FO process removed COD at a higher rate (59%) than O3 (33%) while colour removal was similar (89% and 91%, respectively). The CF process removed both COD and colour at rates similar to the FO process. A colour range of 150–250 platin–cobalt (Pt–Co) unit was assessed for toxicity.

Abstract

This study evaluates the effectiveness of Fenton'soxidation (FO) process and ozone (O3) oxidation compared with a coagulation–flocculation (CF) process to remove effluent toxicity as well as colour and COD from a textile industry wastewater. Daphnia magna was used to test acutetoxicity in raw and pre-treated wastewater. The operational parameters for each process were determined on the basis of complete toxicityremoval. The FO process removed COD at a higher rate (59%) than O3 (33%) while colour removal was similar (89% and 91%, respectively). The CF process removed both COD and colour at rates similar to the FO process. A colour range of 150–250 platin–cobalt (Pt–Co) unit was assessed for toxicity.
