Storm runoff from road contains significant loads of micro particles, heavy metals and organic constituents. The majority of storm runoff pollution is trapped in particles smaller than 100 μm in diameter. Storm water data collected from two road sites in the Chungbuk, Korea areas to characterize the road runoff. The quantity of road runoff and quality constituents, including COD, SS, TKN, PO4-P, TP, Fe, Cd, Cu, Cr and particle size distribution were analyzed. There were three major objectives of this study. The first objective was to characterize the road runoff and first flush. The second objective was to measure and evaluate particle size distribution of the road runoff. The final objective was the assessment of the hydrodynamic filter separator (HDFS) for treatment of micro particle in road runoff. Because many road runoff pollutants are associated with micro particles, new device called hydrodynamic filter separator has been developed for the treatment of road runoff.
