Abstract

Biolgical activated carbon (BAC) processes are known to effectively remove organic pollutants in raw water, and biomass and attached bacterial species play an important role in removing process. In the present study, changes of bacterial biomass in granular activated carbon (GAC) process according to the depth and operating period were investigated. In addition, changes of bacterial biomass were also confirmed after UV exposure prior to the GAC process. Results from this this study showed that the bacterial biomass was decreased dependently according to the depth of GAC process. In case of UV pre-treatment, the bacterial biomass was declined significantly over the period of operation. However, changes in bacterial community were not shown during operation period without UV pre-treatment process. In conclusion, findings from this study may provide the useful information about the management of BAC process.
