MBR research trends − the cost of unoriginality

Sharp-eyed readers of this blog may have received the impression that I am not a huge fan of MBR research publications based on fouling. It could be argued that there is far too much effort dedicated to this single area and there is at least some fuel for this particular fire.

Influent quality − garbage in …?

Many of the challenges faced by MBRs have very little to do with the membrane technology and everything to do with the components or issues around it.  This can include the software, the screens, the maintenance scheduling, the training but also influent flow and quality.

MABRs (or membrane aeration bioreactors to you and me)

The term 'MABR' was first introduced by Mike Semmens of the University of Minnesota. The large body of research at Cranfield University was actually preceded by a collaborative research programme on MABRs between Tom Stephenson of Cranfield and Semmens in the early 1990s.

The cost of ceramic membranes for MBRs

Surely, ceramic membranes are just too damned expensive, aren’t they? Well, as someone who’s dabbled in cost analysis every once in a while, let’s just run through the process for operating expenditure (OPEX).

Exploring the possibilities of MBR Modelling

I have, in my time, had the pleasure of conversing with such people working on both biological and membrane separation processes and there can be little doubt that they have all demonstrated a keen interest in the practicalities of the technologies.
