Abstract:

The utilization of aerobic granular sludge (AGS) conjugates compactness and

productivity. But, the formation of granules needs appropriate operational conditions like

food-to-microorganism (F/M) ratio. This research is focused on the optimal F/M ratio to

maximize the reactor capacity while forming AGS. Aerobic granulation could be achieve

with a COD removal efficiency higher than 90% for a F/M ratio below

1,5 kgCOD.kgVSS‐1.d-1.
