The internet is awash with pie charts demonstrating that 50−55% of energy costs at a classical municipal WWTW are associated with aeration. The percentage is slightly larger for MBRs because of the requirement for membrane air scouring as well as process aeration.

The factors governing implementation of an MBR (or any other technology, for that matter) can largely be reduced to a single parameter: money. So here's a list of the top 10 key factors to take into consideration when implementing an MBR.
I was privileged to be invited to the 10th Annual Ovivo MBR Operator’s Workshop in Austin TX last week (May 2015). Last year, I was only able to present via Webex from Doha and it meant I didn't get to see the other presentations. This year, I realised what I'd missed.
It's often the case that if you ask the price of anything at all relating to engineering, you'll get the answer 'It depends'. Trying to establish the cost of an MBR installation is no different: there are many different components of cost, and many ways of determining them.
