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

Ancillary equipment for membrane bioreactors
Unlike classical activated sludge treatment, MBRs require fine screening to 1-3 mm, and membrane process operation control

Systems integration: Putting it all together
The design of a centralised unit to control the complete multi-step process in a WWTP is the job of the systems integrator. The SI is responsible for linking the individual control systems, as well as the commissioning and start-up of the installed plant.
