About The MBR Site

About The MBR Site
The MBR Site is owned by Claire and Simon Judd (of Judd & Judd Ltd, trading as The MBR Site, SludgeProcessing.com and Judd Water & Wastewater Consultants), based in Bedfordshire in the UK.
Launched in 2010, The MBR Site is now an established leading source of information and guidance for everyone interested in membrane bioreactors for water or wastewater treatment − practitioners, researchers and technology providers.
The website complements our books:
- The MBR Book (published by Elsevier in 2010)
- Industrial MBRs (published in 2014) and
- Watermaths, third edition (published in 2019 by IWA)
as well as The MBR Group, a lively discussion forum of over 9,000 professionals worldwide on LinkedIn.com.

Our purpose
We aim to promote membrane bioreactor technology to the wider world, by introducing the technology to those new to the subject, as well as providing information and guidance to those already active in the field.
At the heart of our website sit our free listings directories:
but we also publish MBR news, feature articles, training and events, and we are reviewing and expanding our content continuously. Our latest upgrade, in 2021, has introduced (among other things) a whole new information architecture for our 400+ pages, on which we can build for the coming years.
We very much welcome your support. Constructive feedback and comments are always welcome, and if you would like to contribute − either by writing feature articles, adding a listing, correcting errors or advertising with us − then we would be very interested to hear from you.
You can contact us on [email protected].
