Abstract

This study was evaluated the characteristics of organic materials in the water source and the removal characteristics of organic materials by ultrafiltration including mixing and coagulation process. As a results of the study, it was found that the total organic carbon in the water source was mostly caused by the dissolved organic materials. As the specific ultraviolet absorbance value of the raw water was low, we found the soluble organic material has a high hydrophilic and low molecular material composition ratio. As a result of ultrafiltration experiment including mixing and coagulation process, the average removal rate of total organic carbon, dissolved organic carbon and ultraviolet absorbance at 254 were 37.9%, 30.3%, and 28.2%, respectively.

본 연구는 상수원수 내에 존재하는 유기물질 특성을 평가하고 혼화 응집 공정을 포함한 UF 막여과에 의한 유기물질의 제거 특성을 평가하였다. 연구결과, 상수원수내의 총유기탄소는 대부분 용존성 유기물질에 기인함을 알 수 있었으며, 원수의 SUVA 값이 낮게 측정됨으로써 용존성 유기물질은 친수성, 저분자 물질의 구성 비율이 높음을 알 수 있었다. 또한 혼화 응집 공정을 포함한 UF 막여과 처리 실험 결과 총유기탄소의 제거율은 평균 37.9%, 용존유기탄소의 제거율은 평균 30.3%, 그리고 $UV_{254}$의 제거율은 평균 28.2%로 나타났다.
