Abstract
Laboratory scale reactors treating domestic wastewater were operated for selection of aerobic granules. We found the formation, structure, biological performance and microbial community structures of aerobic granules were affected by the rates of the influent wastewater feed. In a reactor with slow feed (R1), poor granulation occurred during the 190 day operation. However, good granulation occurred in the fast feed reactor (R2) after 85 days of operation. Analysis of microbial community shifts indicated that granulation in R2 correlated with increasing abundance of Gammaproteobacteria (uncultured Competibacter sp.). In R1 the formation of loosely structured, large aggregates and then later small granules correlated with high abundance of Flavobacterium and Commamonas spp. The results suggest that slow reactor feed rates are detrimental to granule formation, which is important to consider in the full-scale application of the technology.
