Characterization of critical flux in a submerged membrane bioreactor system
Membrane bioreactor (MBR) systems have been widely used as a replacement to secondary clarifier in wastewater treatment plants. However, membrane fouling and its consequences in terms of plant and maintenance costs limit the application of MBRs. To mitigate this problem, industry often operates a...

| description | Membrane bioreactor (MBR) systems have been widely used as a replacement to secondary
clarifier in wastewater treatment plants. However, membrane fouling and its consequences in
terms of plant and maintenance costs limit the application of MBRs. To mitigate this problem,
industry often operates at sub-critical fluxes. Such a practice links to the concept of critical flux
which is defined as the flux below which there may be no fouling of the membrane. Various
experimental methods for measuring critical flux and the effect of time intervals and pressure
stepping intervals were studied. The results clearly showed that different experimental methods
provide different accuracy for critical flux determination. Both time intervals and pressure
stepping interval were also found to cause different level of membrane fouling. |
