영문 초록

Storm water pollution has been the various concerns over the past decade. Decreasing the contamination levels of runoffs to the minimum accepted levels to protect the water quality of rivers, estuaries, streams, lakes, seas, and other bodies of waters have been the objectives of various storm water best management practices (BMP) implemented. BMPs has been augmented to existing water treatment facilities to provide additional resources for potable water usage. Novel filter materials are used to improve the performance of media filters and extend their capabilities to removing other pollutants such as organic/aromatic hydrocarbons and heavy metals. Among the novel materials being considered are photocatalyst nanoparticles coated into the sand media filter. Photocatalysts have been applied in the degradation of organic pollutants with the help of visible light irradiation. This paper describes the synthesis and use of nanoparticle-coated zeolite media filter to remove dissolved metals (Cu and Zn). Catalyst surface analysis revealed that the Cu and Zn were chemically adsorbed, and were transformed into its corresponding elemental forms.
