The purpose of this study is to investigate the characteristics of undersea tunnel construction wastewater and treatment using Highrate Clarifier filtration (HCF). The raw water characteristics of pH, turbidity, salinity, T-N and CODMn were 10.2, 597 NTU, 15 ‰, 13.03 mg/L and 16.25 mg/L, respectively. The linear velocity (LV) of HCF were 300 and 500 m/day. As a result, the efficiency of turbidity and heavy metals removal at linear velocity of 300 m/day were higher than that at LV 500 m/day. For Fe and Mn reduction, the efficiency of HCF were in the range of 14~25% more efficient than that of HF.
