Recently, in order to meet the Strengthened effluent standard retrofitting the conventional activated sludge process into the advanced treatment process is on the increase, and the changes in microbial biomass fractions within the corresponding process largely affect the effluent water quality. depending on the operational condition. In this study, in order to evaluate the Changes in microbial fractions within the process, depending on the process change. weekly monitoring and respirometric method performed. As results from observing profile changes. the acclimation towards corresponding process and substrate was completed after about 4-5 weeks of adaptation period. The biomass fractions of heterotrophs and autotrophs for activated sludge and BNR process sludge changed from 19.0-21.8 to 15.8-16.1% and from 0.8-1.0 to 7.6-8.8% in VSS. respectively. Based on these results, it was concluded that the Changes in characteristics of activated Sludge process and advanced treatment process, depending on the microbial acclimation, can be better explained.
