文摘

Activated sludge biomass was converted to GAO dominated biofilm within eight weeks. Biofilm removed organic carbon anaerobically and stored as PHA. Storage ability of biofilm was revived after exposure to atmospheric oxygen. Biofilm operation required less energy as it avoids costly O2 transfer into wastewater. The reactor could be integrated with nitrogen removal (e.g., anammox) technologies.
