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.
Operation & maintenance parameters for an MBR are those relating to a) the membrane separation and b) the biological process
Pressure-driven membrane processes with liquid permeation can operate in one of two modes: ‘dead-end’ or 'crossflow'.
Membranes foul when the surface is coated with solutes and colloids; clogging is the filling of membrane channels with solids

The critical parameter in MBR processes is the flux, or volume of permeate generated per unit area of membrane per unit time
The biological process parameters in an MBR do not differ from those of a CAS process, though MBRs can operate at longer SRTs
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.
