N2 - The removal efficiencies for ammonium (NH4 +) and total phosphorus (TP) from runoff using two layered filtration systems (LFS-A, with a turf surface, and LFS-B, with a permeable brick surface) were investigated in six repeated experiments. The results indicated that the removal efficiencies for NH4 + and TP from infiltrated water using LFS-A were as high as 90.92 and 91.60%, respectively, while the efficiencies resulting from LFS-B ranged from 86.67 to nearly 100% and 90.29 to 99.09%, respectively. However, there was a significant difference in the comprehensive removal rates (CRRs) for NH4 + and TP between LFS-A (400 and 70 mg·m-2·h-1, respectively) and LFS-B (174 and 54 mg·m-2·h-1, respectively). Some engineering measures, such as the utilization of replanted turf, may reduce the CRRs for pollutants for long periods of time; while no significant relationships between the CRRs of NH4 + and TP and their initial concentrations were observed.
