The efficiency of sequencing coagulation and photocatalytic
oxidation for the treatment of real textile wastewater was studied
according to the optimum conditions determined for removal of AR
73. In addition, a comparative study was performed to evaluate the
role of each process involved in the removal of AR73. Following the
determination of raw wastewater characteristic, the removal effi-
ciency (%) of COD was evaluated to determine the efficiency of
sequential process for the treatment of a real textile wastewater
