Abstract

Geosmin and 2-methylisoborneol (2-MIB) produced by cyanobacteria during algal blooming in surface water are the major taste-and-odor-causing compounds in drinking water and need to be removed. Activated carbon is often used in treatment plants for the mitigation of odor problem. However, there is a lack of information on the effect of pore size distribution and particle size of activated carbon for adsorption of both odor compounds. Therefore, we studied the effect of pore size distribution and particle size of activated carbon on the adsorption of geosmin and 2-MIB. When comparing the adsorption of geosmin and 2-MIB between activated carbon fiber (ACF), powdered activated carbon (PAC) and granular activated carbon (GAC), the order of removal efficiency was PAC > ACF > GAC. As a result of comparing PACs with various pore distribution characteristics, well-developed micropores on activated carbon were found to be favorable for adsorption of geosmin and 2-MIB. For particle size, smaller was more effective for adsorption of geosmin and 2-MIB.

녹조현상 발생시 남조류에 의하여 발생하는 이취미 물질인 Geosmin과 2-methylisoborneol(2-MIB)는 수돗물에 냄새를 유발하는 원인 물질로서 제거가 필요하다. 일반적으로 정수장에서는 이취미 물질의 제거를 위하여 활성탄을 사용하고 있으나 활성탄의 기공 분포와 활성탄의 입자크기가 이취미 물질 흡착제 미치는 영향에 대한 정보는 부족하다. 따라서, 본 연구에서는 다양한 활성탄의 기공분포와 활성탄의 입자 크기가 이 취미 물질 흡착에 미치는 영향을 살펴보았다. 분말활성탄(PAC), 입상활성탄(GAC), 활성탄소섬유(ACF)의 이취미 물질 흡착을 비교한 결과, PAC > ACF > GAC 순서로 이취미물질 흡착제거효율이 높았다. 다양한 기공분포 특성을 갖는 분말활성탄들을 비교한 결과, 미세기공이 잘발달된 경우가 Geosmin과 2-MIB의 흡착에 유리한 것으로 나타났으며, 입자 크기의 경우에는 작을수록 Geosmin과 2-MIB의 흡착에 보다 효과적이었다.
