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.
