Air Products’ Halia® aeration systems can be utilized for aeration in Membrane Bioreactors (MBRs). With oxygen aeration, MBRs can be operated at higher biomass concentrations without the oxygen transfer limitations of air systems. This results in high treatment rate and reduced basin footprint. The use of the Halia aeration systems in MBRs also reduces the foaming and VOC emissions issues associated with air-based systems.
