Technology overview
Membrane Aerated Biofilm Reactor (MABR)
conceptual process
Air inlet
A gas transfer
membrane delivers
oxygen to a biofilm
attached to the
surface of the
membrane
Oxygen transfer is
4X more efficient
Air outlet than fine bubble

MABR compared to conventional biofilm
Reaction occurs at the surface Reaction occurs in the biofilm
Favors growth of nitrifiers at
