Microbial community in a novel bag-based fixed activated sludge system
In this study, a novel bag-based fixed activated sludge (BBFAS) system utilizing mesh bags to contain the sludge was developed for low carbon/nitrogen ratio wastewater treatment. Pilot-scale experiments showed that the BBFAS system effectively removed pollutants and successfully prevented sludge abnormalities. High-throughput sequencing of the 16S rRNA gene revealed a significantly different bacterial community structure in the BBFAS system compared to the conventional activated sludge system.
