MBR 공정에서 막오염 완화제가 막여과 특성에 미치는 영향
이우녕,이정학 한국공업화학회 2005 응용화학 Vol.9 No.1
Membrane filtration characteristics are observed with and without Membrane Fouling Reducer (MFR) in Membrane Bioreactor (MBR) process. Membrane filtration performances are improved as increased in MFR concentration about 50 ppm. However, filtration performances are deteriorated over 50 ppm. Microbial floc size, soluble COD and soluble EPS concentrations are changed with variations of MFR concentrations. And they affects the filtration performances. Variations of these factors are owing to the variations of zeta potentials of microbial flocs. Variations of zeta potentials may affects flocculation and deflocculation.
