ABSTRACT Kim, K.-J. and Jang, A., 2017. The fouling characteristics of NOMs on the microfiltration ceramic membrane. In: Lee, J.L.; Griffiths, T.; Lotan, A.; Suh, K.-S., and Lee, J. (eds.), The 2nd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 79, pp. 60–64. Coconut Creek (Florida), ISSN 0749-0208. The filtration performance and fouling characteristics of mixed natural organic matters (NOMs) on monolith ceramic microfiltration (MF) membrane was investigated in a dead-end mode under constant transmembrane pressure (TMP) with periodic backwash. Humic acid (HA), bovine serum albumin (BSA), and sodium alginate (SA) were used for the investigation of the fouling potential. In a pilot-scale filtration test, the fouling characteristics of NOMs were evaluated by the various operation conditions, including solution pH, foulant mixture, and rate of flux recovery. The NOMs and mixed NOMs caused severe permeability reduction, and the fouling potential varied significantly with d...
