제목 Effect of Disintegrated Sludge Recycling on Membrane Permeability in a Membrane Bioreactor Combined with a Turbulent Jet Flow Ozone Contactor
초록 We have combined a turbulent jet flow ozone contactor (TJC) with a membrane bioreactor (MBR) to establish a zero-discharge system in terms of excess sludge in the MBR. The TJC-MBR system was compared with the conventional MBR (Control-MBR) with respect to i) the size and zeta potential of the sludge particles, ii) the loosely bound (LB) extra-cellular polymeric substances (EPS) and tightly bound (TB) EPS of the microbial flocs, iii) the porosity and biovolume of the bio-cake accumulated on the membrane, and iv) the membrane filterability.
