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.
