The performance of the slow sand filter was examined using the landscape water with the experimental period of 46 days. The filter installed was similar to the traditional slow sand filter; expect that the top 5-cm sand was changed to the quartz sand. In this study, the variations of the turbidity, COD, BOD and TN were measured based on the filtration rate of 0.2m/h. Results showed that the average...
Highway runoff is one of the important water resources in urban areas, though severe pollution has curbed its direct use. In this study, a soil infiltration system is proposed for treatment of highway runoff. Bench-scale experiments with different inflow concentrations and system operation modes (continuous/intermittent) have been designed to simulate the highly varied inflow rate and pollution load...
