Anyone working in wastewater cannot have failed to have noticed the increasing attention being paid to micropollutants. These are substances capable, we are assured, of wreaking havoc on the environment with potentially significant risk to human health.
The MBR Blog
I was privileged to attend a defence of a student PhD in the beautiful surroundings of Delft earlier this week. Apart from a rather bizarre protocol to which the university strictly adhered, entailing all examiners dressing as Jedi knights, it was a most agreeable experience.
It is recognised that MBRs − and the immersed configuration (iMBR) in particular − operate more efficiently when fluctuations in loading are reduced. If the option is available, a buffer tank can reduce fluctuations sufficiently to allow more optimal use of the membranes.
High operational costs, and energy costs in particular, are often seen as the Achilles heel of MBRs. Energy efficiency in operating MBRs has attracted a great deal of attention, particularly in relation to blowing air and aeration energy efficiency.
