Municipal wastewater with limited organic substrate concentrations may pose a challenge for the application of aerobic granular sludge technology. Readily biodegradable carbon or chemical oxygen demand (rbCOD) is necessary for biological phosphorus removal (bio-P), and a sufficient organic loading rate is necessary for biofilm formation. This project investigated the impact of substrate availability on granule formation and development, and how selective wasting can be used to retain granules in a continuous flow system.
