In this work, coagulation features and characteristics of dissolved organic matter (DOM) in combined sewer overflow (CSO) wastewater were investigated. Ferric chloride (FeCl3) and polyaluminum chloride (PAC) were employed in the coagulation process. Results showed that both FeCl3 and PAC are effective in removing turbidity and total phosphorus (TP). Removal efficiencies were all above 90% when dosages were reasonable. Chemical oxygen demand (COD) removal efficiency was between 60% and 70%. T...
