4.2. Bioaugmentation of the selected strains on municipal wastewater treatment
Considering the significant effect obtained from B. Subtilis (R1) and P. Aeruginosa (R2) and the
“SludgeHammer” (R3) for degrading TOC in the synthetic wastewater, the three strains were selected for
additional degradation experiment using raw municipal wastewater. The strains were added (4% inoculums has
108CFU/ml) as a single strain of R1, R2, or R3 and a combined strain of R1+R2. The controlled bioreactor was
operated without bioaugmentation. As can be seen in Fig. 3, the removal efficiency of TOC in the bioaugmented
reactors were clearly better (6 -16% higher) than controlled reactor. The reactor inoculated with the selected
combined strains (R1+R2) yielded relatively better treatment performance compared to the reactor inoculated with
single strain of either R1, R2, and R3.
