Fundamentals of MBR design − the immersed membrane bioreactor process
The design of a membrane bioreactor system largely relates to the configuration of the membrane, the membrane separation process, and the biotreatment process.

MBR building blocks
An MBR has the same components as a classical activated sludge process, but with membrane separation replacing sedimentation

Topic
MBRs − choosing the process and membrane configuration
MBRs have two process configurations, immersed and sidestream, their implementation depending on wastewater quality and flow
Topic
Immersed vs sidestream MBRs − flux and shear
Shear is the force created when an air or liquid stream flows parallel to the membrane surface, helping to suppress fouling
Topic
Ancillary equipment for membrane bioreactors
Unlike classical activated sludge treatment, MBRs require fine screening to 1-3 mm, and membrane process operation control

MBR academic research, past and present
Academic research into MBRs has been dominated by studies of membrane fouling and foulant characterisation. Key topics, such as process failure risk, chemical cleaning impacts on membrane life, and pretreatment requirements, have been largely overlooked.
