MBRs − towards zero energy and zero waste

A long-standing notion regarding wastewater is its potential to provide a useful resource, rather than being viewed as a waste. This is not completely far-fetched. Wastewaters high in readily biodegradable organic carbon can be anaerobically treated to provide methane.

Industrial resolution − challenging wastewaters

A while back I posted a discussion on LinkedIn asking for comments on what readers regarded as being the most challenging industrial effluent for treatment using an MBR. It was largely ignored (a common enough, and entirely justifiable, happenstance).

Really cleaning up − clogging in MBRs

Having spent the best part of 6−7 years bemoaning the lack of understanding of clogging of MBR membrane channels, it is with a certain amount of pride that I can report that the group at Cranfield has recently produced three papers on the topic.

There can be few things more confounding in MBR operation and maintenance than the development of filamentous bacteria in the biotank. These are 'string-like' micro-organisms, with different species apparently prevailing under different conditions.
