Rapid in-situ enrichment of anammox bacteria from activated sludge via nitrate induction: pilot-scale demonstration and mechanistic insights.
The enrichment of anaerobic ammonium-oxidizing (anammox) bacteria from common activated sludge is slow, greatly limiting the application of anammox-based technologies. Herein, a nitrate-induction strategy was applied during the early enrichment stage to accelerate the enrichment of anammox bacteria. Compared with the c...
