Microbial Activity in Activated Carbon Filters

Physical and chemical adsorption by aged biological active carbon (BAC) filters were observed for some organic matter fractions, and may represent important removal mechanisms during periods of low microbial activity.

The moment analysis of pulse responses was applied to the biological activated carbon (BAC) in order to elucidate its microbial activity and adsorption capacity separately. The microbial activity derived from this approach was focussed on and the following was found in this work. First, the activity of micro-organisms attached on activated carbon was higher than those on other carriers. Second, the microbial activities of bench-scale BACs treating pond water varied with the pretreatments by ozone and chlorine, but did not change considerably during the operation for about one year. Also, an the empirical relationship was found between the microbial degradation rates of pulse-injected glucose and background dissolved organics. It was concluded that this approach is useful for evaluating the microbial activity in BAC in a relatively easy manner.

Bleach plant effluent from the pulp and paper industry was treated by means of the anaerobic biological granular activated carbon process. It was found that over 50% of the COD and colour could be successfully removed from this effluent. The adsorptive capacity of the activated carbon was extended as a result of microbial activity inside the anaerobic reactor. The results of this investigation suggest that the anaerobic biological granular activated carbon process could be used to alleviate the pollution problems experienced by the pulp and paper industry.
