Abstract | Filtration experiments were conducted to determine the characteristics of manganese removal in filtration using 4 different filter media including sand and manganese sand(MS). Filtration velocity was 123 m/d and the flow rate was $3.9m^3/d$ per column. Duration of these experiments was about one year, and manganese dioxide accumulation, turbidity removal, manganese removal, and organic material removal were examined depending on filter media. When filter influent(residual chlorine 1.0 mg/L) with an average manganese concentration of 0.208 mg/L was fed through a filter column, the sand+MS and MS columns removed 98.9% and 99.2% of manganese respectively on an annual basis. When there is need to replace the sand filters with a MS filter to remove manganese, it was shown that the replacement of a partial sand filter with MS had adequate manganese removal. 여과공정에서 망간제거특성을 고찰하기 위하여 모래, 망간사 등의 4가지 여재를 사용한 여과실험이 실시되었다. 여과속도는 123 m/d였고, 칼럼당 유입량은 $3.9m^3/d$이었다. 실험기간은 약 1년이었으며, 실험기간 동안 여재별로 이산화망간 부착량, 탁도제거율, 망간제거율, 유기물제거율 등을 고찰하였다. 평균 망간농도 0.208 mg/L의 여과지 유입수(잔류염소 1.0 mg/L)를 사용하여 여과실험한 결과 모래+망간사 칼럼은 98.9%, 망간사칼럼은 99.2%의 망간제거율을 보였다. 기존 모래여과지를 망간제거를 위해 사용할 경우 여층의 전부를 망간사로 교체하지 않고 일부만 교체하여도 망간제거에 충분한 효과가 나타나는 것으로 조사되었다. |
