What are membrane bioreactors?
An introduction to MBRs
‘Membrane bioreactor’ (MBR) is generally a term used to define wastewater treatment processes where a perm-selective membrane, eg microfiltration or ultrafiltration, is integrated with a biological process − specifically a suspended growth bioreactor.
MBRs differ from ‘polishing’ processes where the membrane is employed as a discrete tertiary treatment step with no return of the active biomass to the biological process.
Almost all commercial MBR processes available today use the membrane as a filter, rejecting the solid materials which are developed by the biological process, resulting in a clarified and disinfected product effluent.
A membrane bioreactor is essentially a version of the conventional activated sludge (CAS) system:
Fundamentals of MBR design − the immersed membrane bioreactor process
While the CAS process uses a secondary clarifier or settlement tank for solid/liquid separation, an MBR uses a membrane for this function. This provides a number of advantages relating to process control and product water quality.

We are installing a MBR system in the industrial town wastewater treatment plant.
Do you think the polymer in industrial effluents can shorten the useful life of our system?
Not sure. It’s worth posting this query on The MBR Group on LinkedIn
Thank you for your attention
We use to separate the sludge from the device Multi disc screw press, that the effluent of the device has a large amount of polymer.
Can I kindly ask whether it is possible to have the anoxic tank/zone, serving as a sediment/septic tank, all regards to a small system of 10m3/hr, with no mechanical agitation?
Thanks & Kind Regards,
Only if it's the right shape and size to allow particles to settle.
WE require 500 KLD MBR technology Sewage Treatment Plant. Please mail me quotation immediately.
Thanks and Regards,

hello thanks to your useful site and information, i cant open the link of your site, please guide me. for example this link :https://www.youtube.com/embed/99j2Y-Zo5KI?autoplay=0&rel=0&byline=0
Hi Sara - the link works for us. You could try another browser or go to YouTube and then search for our channel which is 'Judd Water and Wastewater Consultants'. You will find the video on there. Hope that helps.
