Abstract :
The colonization of columnar activated carbon was developed. Some analysis of several physical–chemical, biochemical and microbiological methods (indicators) used to characterize the BAC biofilm´s composition and activity was provided. The filtration column filled with columnar activated carbon was operated incessantly for 72 days in the condition of natural colonization in a dynamic flow and poor nutritional status. The mature biofilm was observed after 53 days. By contrast, it was found that the columnar activated carbon showed a faster colonization speed and higher removal efficiency of NH3-N, NO2-N, UV254, CODMn, DOC and AOC, which were 37.2%, 35.8%, 25.2%, 30.2%, 22.7% and 171, respectively.
