“…자연환기가 부족한 상황에서 벤젠, 포름알데히드와 같은 휘발 성유기화합물(VOC)을 포함한 유해화학물질이 실내에 축적되며 (Allen and Miguel, 1995;Miguel et al, 1995;Spengler and Sexton, 1983), 이들의 농도는 공간의 부피, 오염물질의 발생 및 제 거율, 환기량, 외부의 기상상황, 그리고 실외의 오염물질의 농도 등 에 따라 민감하게 영향을 받는다 (Guieysse et al, 2008). 새집증후 군이 나타나는 신축건물에서는 VOC나 포름알데히드의 농도가 높 게 유지되는 것으로 조사되었으며 (Cho and Sohn, 2010;Lee and Chung, 2011;Jones, 1999;Jung et al, 2007;Sekine, 2005), 오 염물질은 환기를 통해 효과적으로 제거할 수 있으나 에너지 소비와 외부환경조건에 따른 환기불가 등의 문제도 발생한다 (Ekberg, 1994).…”

This study was carried out to investigate the formaldehyde (FA) filtration pattern of additional media for indoor biofilter system. Dry pellet type activated carbon (PAC), activated clay (ACL), zeolite, diatomite, pumice and loess ceramic ball were tested. In the case of dry filter media, formaldehyde purification efficiency was the most excellent with activated clay and then was good with the activated carbon, diatomite, zeolite, and pumice order. PAC and ACL decreased the FA concentration with exponential pattern resulted from dynamic balance between emission and purification. Zeolite, diatomite, pumice, and loess ceramic ball showed high filtration rate at initial time and then increased FA concentration result from breakthrough. PAC, zeolite and diatomite could be recommended as additional filter media for biofilter system considering FA filtration and breakthrough characteristics. FA filtration and breakthrough characteristics were improved with wet media except PAC and ACL. In particular, purification performance improvement and breakthrough mitigation were higher in pumice and loess ceramic balls. PAC+ZEO mixing showed the most high purification performance and breakthrough mitigation in all mixing methods. Thus mixture of PAC with zeolite and vertical mixing could be recommended as additional filter media to improve the FA purification ability and pressure drop with indoor air biofilter system.
