Oxygen mass transfer is a key parameter for processing aerobic bioreactors in terms of operational costs and efficiency. In membrane bioreactors, a reduction of the aeration capacity is often observed at high solid ratios, caused by the presence of solids and the non-Newtonian properties of activated sludge.
