Urban storm runoff from road contains significant loads of micro particles, metal elements, particulate and dissolved solids and organic constituents. Micro particle is important when considering pollution mitigation because pollutant metal and organics have similar behavior with particles. The objective of this research is to evaluate the Screen Trap device performance for simulated road storm runoff treatment. A various type of materials such as road sediments, silt soil, crushed paper, perlite, granular activated carbon were used for simulated particle, and to determine the removal efficiency with various surface loading rate. In laboratory scale Screen Trap study, the operation ranges of surface loading rates were from 227 to 1,862 m3/m2/day. The Screen Trap removal efficiency ranges were form 39.2 to 95% based on SS.
