Résumé

This study explains how small operational differences support excellent granulation in aerobic granular reactors. Short settling time promoted granulation in AGS reactor. Gene expressions based on mRNA revealed much higher ammonium monooxygenase (amoA) in conventional reactor biomass than in the aerobic granular reactor (AGS) biomass during a complete cycle operation. The number of glycogen accumulating organisms in conventional was much higher than in the granular reactor. The denitrifying functional genes in the granular systems were upregulated in anaerobic and aerobic phases. The granular reactor removed 1.84 kg COD-m
