“…비점오염원 중 강우유 출수의 수질 상태를 파악할 수 있는 주 오염물질은 부유성 고형물(suspended solid, SS)로 유기물, 무기물 등을 함께 수반하고 있으며, 강우 시 초기 세척 현상을 통해 고농도의 비점오염원을 유출한다. 따라서 SS의 제거율은 다른 오염물 질들의 제거율 지표로도 이용될 수 있다고 여겨지고 있다 (Hwang et al, 2017). 이러한 이유로 우리나라의 '비점오염저 감시설 설치 및 관리⋅운영 매뉴얼' (ME, 2016) (Choi and Shin, 2002).…”

Stormwater runoff is a major source of nonpoint source pollution, contributing 22-40% of the total pollution load in 4 major rivers, which has a significant impact on aquatic ecosystems. The criteria for installation of nonpoint pollution abatement facilities in Korea focuses on the removal of suspended solids. Since the load of dissolved phosphorus and heavy metals in stormwater runoff is increasing, it is necessary to develop a method to reduce dissolved materials as well. In this study, the efficiency of using clay granule, zeolite, blast furnace, and basic oxygen furnace slag (from lab-and pilot-scale experiments) to remove SS, phosphorus, and heavy metals from surface waters was evaluated. Among the four types of filter media, the removal performance of clay granule for SS and basic oxygen furnace slag for phosphorus and heavy metals was excellent. As a result, the clay granule and basic oxygen furnace slag were selected as the filter media. In the pilot column test, 89.5% of SS, 77.6% of phosphorus, 87.3% of Zn, and 67.5% of Cu was removed, indicating stable removal efficiency, with a head loss of 3.8 cm. It satisfied the nonpoint pollution abatement facility installation criteria of functioning at a linear velocity 20 m/h. The clay granule and basic oxygen slag filter would be a useful addition to a nonpoint pollution abatement facility.

A filtration system widely receives attention because of its excellent total suspended solid (TSS) removal efficiency. However, clogging leads to increasing head loss in a filtration system. Herein, we investigated the TSS removal efficiency of a fiber filter based on the filtration method and TSS properties to determine the performance of the filter in a lab-scale experiment. Furthermore, we found the TSS removal efficiency, head loss of the filter media, and recovery ratio of the head loss after backwashing in a pilot-scale experiment. The TSS removal efficiency was 60-80% in the lab-scale test and higher than 80% in the pilot-scale test, which met the designated standard. In addition, the low head loss (< 20 mm) and high recovery ratio of the head loss (100%) showed the excellent performance of the filtration system.
