What is the role of MBBR media in biological phosphorus removal?

MBBR media play a supportive role in biological phosphorus removal (EBPR) in wastewater treatment by providing a suitable environment for phosphorus-accumulating organisms (PAOs) when integrated into systems with specific zones. MBBR media can:
1.Zone Integration: Incorporate pre-anoxic and anaerobic zones for PAOs to thrive and facilitate phosphorus release.
2.Biofilm Diversity: Host PAOs within the biofilm, enabling phosphorus storage and removal.
3.Sequential Treatment: Aid in reducing organic loads before phosphorus-specific removal processes.
While MBBR media are not specifically designed for EBPR, they can be part of systems that promote phosphorus removal when combined with appropriate process design.
