Article Preview

In this study, to effectively control urban non point source pollution, natural and artificial materials which were processed in various ways were charged as a filter media in a real size urban non point source pollution plant(EcoTank) and compared and evaluated the efficiency of filtering solid and organic compounds. The efficiency of filter media was evaluated after collecting dust from urban surface and artificially producing runoffs to evaluate runoff control efficiency of pollutants that caused from pollution in urban streets. To evaluate the efficiency of pollutants runoff control depending on different filter types, EPP(Expanded polypropylene), GAC(Granular activated carbon), Zeolite, Mix-1(EPP in the upper part, GAC in the lower part), Mix-2(GAC in the upper part, EPP in the lower part) was charged to the EcoTank and conducted experiments in an identical condition[6]. As a result of the filter evaluation using real size reactor, EPP was identified as the best filter media for non point source pollution runoff control, and the efficiency was in the following order: EPP > Mix-1 > Mix-2 > GAC > Zeolite.
