In this paper, we investigate the characteristics of membrane fouling caused by water temperature in the Membrane bioreactor(MBR) process and try to derive the membrane fouling control by chemical enhanced backwashing(CEB). The extracellular polymeric substances(EPS) concentration was analyzed accor...

EPS 대표물질은? | EPS 대표물질인 Protein과 Polysaccharide의 수온에 따른 막 오염 특성을 알아보고자 하였고, 수온조건 10, 20 및 30˚C에 따라 미생물이 포함된 여과저항 증가율은 9.73×10 8 /m・min, 9. | |
membrane bioreactors 공정의 전망은? | 생물학적 폐수처리 공정에 분리막을 도입한 membrane bioreactors (MBR) 공정은 폭기조 내에 고농도의 MLSS (Mixed liquer suspended solid, 약 8,000〜15,000 mg/L) 를 유지시킴으로써 처리용량 및 처리효율을 도모할 수 있다. 하지만 MBR 공정 운영 중 발생하는 막오염 (fouling) 현상으로 인해 투과수량 감소 및 운전압력 상승 등이 발생하고, 이것은 유지관리비용 상승으로 직결되어 MBR 적용에 제한이 되고 있다 (Farquharson, Zhou, 2010; Han et al. | |
