Bacterial selection during the formation of early-stage aerobic granules in wastewater treatment systems operated under wash-out dynamics
Aerobic granular sludge is attractive for high-rate biological wastewater treatment.Biomass wash-out conditions stimulate the formation of aerobic granules.Deteriorated performances in biomass settling and nutrient removal during start-up have however often been reported.The effect of wash-out dynamics was investigated on bacterial selection, bioma
