| Outline of Final Research Achievements |
This study proposed the design of the bacterial community in activated sludge for advanced wastewater treatment by bioaugmentation to membrane bioreactors (MBRs). For demonstrating this proposal, 4-tert-butylphenol (4-t-BP) was selected as a recalcitrant chemical. Sphingobium fuliginis OMI as a 4-t-BP-degrading bacterium was augmented to a lab-scale MBR. Against the influent concentration at 20 mg/L, the effluent 4-t-BP concentration in the control MBR was 8-14mg/L, indicating insufficient treatment. On the other hand, 4-t-BP was not detected from effluent (<0.1 mg/L) in the bioaugmentated MBR after 7-21 days of inoculation of the bacterium, indicating successful advanced treatment.
