| Abstract | This study aimed to investigate the possibility of using five types of fermented product (FP)to improve the removal efficiency of basicpollutants (under aerobic condition via strong agitation), i.e., non-filteredCODT,BODTand SS presentingin two polluted canalsin Bangkokarea, namely, San Saeb and Kajacanals. The results were compared with the „Control‟experiment, which was without the addition of any fermented products (FPs). Obviously, it was found that the addition of FPs(containinghigh VFA) increased the CODTconcentration of the raw polluted water from 52 tothe range of87–107 mg/L. However, there was no clear-cut conclusion on the benefit of the FP additionin this study. Also, it was apparent that allfivedesignated FPsgave similar treatment results. The only advantage of the FP supplement was to increase the MLSS or bacteria mass in less time, which is good for a startup process. However, bacterial mass (MLSS) can be enhanced through an ordinary startup without necessity of FP addition if there is no any particular problem.In conclusion, BOD and COD removals in the reactors with FP addition were not significantly different from the „Controls‟, which eventually determined that EM and FPsaddition cannot effectively treat polluted water. |
