Membrane bioreactors − operation and maintenance
Operation & maintenance parameters for an MBR are those relating to a) the membrane separation and b) the biological process
MBR operation & maintenance
Key MBR operation and maintenance parameters – membrane side
The most important parameter of an MBR system is the flux, the volume of permeate generated per unit area of membrane per unit time. Other key parameters are TMP, permeability and shear.

MBR operation & maintenance – dead end vs crossflow
Pressure-driven membrane processes with liquid permeation can operate in one of two modes: ‘dead-end’ or 'crossflow'.
Topic
MBR operation & maintenance – fouling, clogging and cleaning
Membranes foul when the surface is coated with solutes and colloids; clogging is the filling of membrane channels with solids

Key MBR operation and maintenance parameters – biological side
The biological process parameters in an MBR do not differ from those of a CAS process, though MBRs can operate at longer SRTs

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.
