This study was undertaken to treat the aqueous solutions containing the organic pollutants, PCP(p-chlorophenol) and DBS(sodium dodecyl benzene sulfonate), by adsorption and biofilm processes using activated carbon fiber(ACF A-15) packed columns. And the changes of trihalomethane formation potentials(THMFP) in the model experimental system was investigated to clarify the mechanisms of the decrease/increase of THMFP in the biological activated carbon treatment. When adsorption of bi-components solution(PCP and DBS) was progressed, DBS , which was initially adsorbed, was replaced by PCP. The final adsorption capacities for these components at SV(space velocity) of 3.6h-1 were in good agreement with the batch single adsorption measurement, but for the SV of 11.3h-1, the adsorption capacity for DBS was found to be decreased. The removal efficiencies for DBS and PCP in bi-components system, were over 50% and 70%, respectively by BAC treatment. In case of treating the bi-components solution(PCP and DBS) mixed with raw stream water, the removal efficiencies for these components were greatly improved to over 90%. It was found that DBS restrains the THMFPs of PCP more or less. However, from the THMFP removal point of view, treating the bi-components (PCP and DBS) feed solution mixed with raw stream water containing abundant biomass, appeared to be more effective than treating the bi-components solution without raw stream water.
