Abstract

For sand and zeolite filter media in stormwater BMPs, media breakage effects on infiltration were investigated. Compaction effort and infiltration force were mainly examined for breakage sources. The 1-D column infiltration tests for un-compacted and compacted media filters were conducted to investigate the breakage effect on infiltration. As a result, the following findings were deduced: 1) particle breakage due to filtration forces was found to be relatively minimal; 2) un-compacted media had lesser amount of crushed particles and permeability fluctuations compared to compacted media; 3) even without the presence of suspended solids in the influent, reduction in permeability was found, which resulted from rearrangement and re-entrainment of media particle itself; 4) only media particle breakage resistance is considered, sand was revealed to have better performance compared to zeolite media.

강우유출수 비점오염 침투처리시설에 사용되는 모래와 제올라이트 필터에서 여재 파쇄가 침투에 미치는 영향을 분석하였다. 여재 파쇄의 원인으로 다짐에너지와 침투력의 영향을 검토하였다. 여재 파쇄가 침투에 미치는 영향을 조사하기 위해 비다짐 및 다짐 침투층에 대한 일차원 컬럼 침투시험을 수행하였다. 시험결과로부터 다음 결론을 얻었다. 1) 침투력에 의한 여재 파쇄량은 상대적으로 적은 것으로 분석되었다. 2) 다짐여재와 비교하여 비다짐여재는 파쇄량이 적고 침투에 따른 투수성 변화도 작다. 3) 부유오염물을 함유하지 않는 침투수가 침투하는 경우에도 파쇄된 여재의 재배열, 재이동이 원인으로 추정되는 투수성 감소가 발생하였다. 4) 여재 파쇄의 영향만을 고려한다면 필터 재료로서 모래의 적용성이 제올라이트 보다 양호함을 확인했다.
