Influence of mixed liquor suspended solids, aeration, and mixing on oxygen transfer parameters in a sequencing batch membrane bioreactor
Aeration is utilized to supply dissolved oxygen to activated sludge in wastewater treatment facilities for the conversion and removal of carbon, phosphorous, and nitrogen. It accounts for 50-90% of a treatment facility’s energy demands. In membrane bioreactors (MBR), the traditional clarifier is replaced with a membrane separation, allowing for operation at higher mixed liquor suspended solids (MLSS) concentration in the bioreactor. While this approach results in a reduced system footprint and higher quality treated effluent suitable for different reuse applications, it comes with an energy ...
