- Abstract
- A coagulation-flocculation (CF) process using aluminum sulfate as a coagulant was employed to treat highlysuspended solids in tunnel wastewater. Response surface methodology (RSM) based on a Box-Behnken design was applied toevaluate the effects of three factors (coagulant dosage, pH and temperature) on total suspended solids (TSS) removal efficiencyas well as to identify optimal values of those factors to maximize removal of TSS. Optimal conditions of coagulant dosage and pHfor maximum TSS removal changed depending on the temperature (4 ~ 24℃). As temperature increased, the amount of coagulantdosage and pH level decreased for maximum TSS removal efficiency during the CF process. Proper adjustment of optimalpH and coagulant dosage to accommodate temperature fluctuations can improve TSS removal performance of the CF process.
