Abstract

The nitrogen removal processes with microbial films attached to various supports have become of interest. In general, biofilm processes provide more stable performance and higher effeciency compared to the conventional activated sludge systems. There is an additional advantage that denitrification proceeds even under aerobic conditions due to the presence of anaerobic zone at the lower layer in a biofilm. Consequently, simultaneous nitrification and denitrification in the same film can be expected when the film thickness is enough. The purpose of the present study is to establish the kinetics of nitrogen removal with the biofilm by analyzing the diffusions and reactions inside the film.
