Control of Membrane Attached Biofilm (MAB) formation and accumulation is a
key aspect in the operation of Extractive Membrane Bioreactors (EMBs). in t
his work, MAB control was attempted in a novel EMB configuration which pres
ents two innovative aspects: the presence of a biphasic biomedium and a con
tained liquid membrane module. This reactor, where the benefits of high she
ar forces and the use of a biphasic biomedium are effectively combined, was
operated without any biofilm formation or reduction in organic substrate f
lux over time.
