What is Confronting Assumptions of Phosphorus-Accumulating Organisms and Glycogen-Accumulating Organisms: Peaceful Coexistence in a Carbon-Limited Sidestream EBPR Demonstration about?
Enhanced biological phosphorus removal (EBPR) is strongly influenced by the influent ratio of readily biodegradable carbon to soluble phosphorus due to the preferences of phosphorusaccumulating organisms (PAO). The sidestream EBPR (S2EBPR) process redirects a portion of return activated sludge (RAS) to a sidestream fermenter, increasing the availability of biodegradable carbon. In this study, we assessed the performance and microbial community structure of a full-scale S2EBPR demonstration supplemented with external carbon dosing. By the end of the 10 month study period, the demonstration achieved a median effluent orthophosphate of 0.3 mg/L. The microbial community consisted of a common core microbiome in the RAS fermenter, EBPR basin, and nitrification basin. The most abundant PAO detected were Ca. "Dechloromonas phosphorivorans", while the canonical PAO Ca. "Accumulibacter" and Tetrasphaera were observed in lower relative abundance. In addition to non-canonical PAO enrichment, the glycogen-accumulating organism Ca. "Competibacter" proliferated throughout the study and at some points outnumbered PAO taxa by 30 to 1 with no tangible performance impacts. This study provides insight
