Heterogeneity of the diverse aerobic sludge granules self-cultivated in a membrane bioreactor with enhanced internal circulation

The present work revealed the heterogeneity of the sludge granules formed in a membrane bioreactor with enhanced internal circulation, and also contributed to better understanding of their forming mechanisms. By continuously carrying out an experiment lasting for more than 3?months with the floc sludge from a local municipal wastewater treatment plant as inoculation sludge, diverse aerobic sludge granules were found to be successfully self-cultivated within the reactor. The results of scanning electron microscopy, fluorescence microscope and high-throughput sequencing measurement indicated that the obtained diverse granules exhibited quite obvious heterogeneity in their basic physico-chemical and microbial properties, and filamentous bacteria actually acted as a main skeleton to keep the self-cultivated sludge granules stable in both their structure and morphology. Furthermore, stable and high COD and TN removal achieved, over 85% and 60%, respectively, which confirmed its usefulness in wastewater treatment.
