N2 - The effluent stream from the industrial production of the herbicide trifluraline (amination water) was submitted to a combined treatment of a physical–chemical process (coagulation) with an advanced oxidation process (Fenton). The recovering of the residual sludge was performed. The combined coagulation–Fenton-sedimentation process proved to be very suitable for wastewater color reduction (91.6%), promoting considerable abatement of the organic load (63.4% COD reduction). According to the fractionary factorial design, the main effects of pH (A) and Fenton sludge (B) variables were considered statistical fluctuations of the process (and not decisive), while the main effects of Fe3+ (C), Fe2+ (D) and H2O2 (E), as well as the interactions between variables A and B, A and E, C and D and C and E were considered significant.
