Coagulation-flocculation sequential with Fenton or Photo-Fenton processes as an alternative for the industrial textile wastewater treatment

The comparison of COD removal efficiency with time using Coagulation-Floculation-Fenton (FT) and Coagulation-Floculation-Photo-Fenton (PF) processes with these obtained using H2O2 re-injection and dosage strategies (pH = 3, Fe2+ concentration = 1 mM). The wastewater was pre-treated by C-F, removing 45% of the original COD.106
