발포성 폐유리 여재 충전 여과장치를 이용한 하수월류수(CSOs)의 인(P)과 부유물질 제거 = Removal of Suspended Solids and Phosphorous in Combined Sewer Overflows (CSOs) by Filtration Apparatus with Expanded Waste-Glass Filter Media

다국어 초록 (Multilingual Abstract)

CSOs (Combined Sewer Overflows) entering water bodies during rainfall cause water pollution problems because they contain sewage components, including suspended solids (SS) and nutrients. Therefore, proper treatment is required to reduce pollution loads on water systems. This study examined the removal efficiency of filtration systems filled with expanded waste glass filter media under various filtration conditions. The filtration column was filled with filter media A with a particle size of 5-14 mm at the bottom and filter media B with a particle size of 0.3-1.4 mm at the top. SS removal efficiency, including smaller particles, increased as the packing height of filter media B increased. The maximum efficiency was 85.7% when the ratio of the filter media B was 50% at a linear velocity of 20 m/hr and SS concentration of the influent was 100-130 mg/L. As the filtration was combined with coagulation, the removal rate of total phosphorus (TP) increased by more than 50% compared to filtration only. Also, PAC (Poly Aluminum Chloride) was more effective in the removal of phosphorus than aluminum sulfate (Alum) due to its higher viscosity. We confirm that the expanded waste glass-filter media are effectively applicable to the CSOs filtration process, and the effective treatment methods associated with coagulation are discussed.
