For an MABR, a membrane aeration biofilm reactor, the membrane is not used to filter the water. Instead, it is used to aerate the solution, replacing the conventional fine bubble diffuser.
The oxygen in the air, or from a pure oxygen source, is introduced in the molecular, or 'bubbleless' form, leading to highly efficient transfer of oxygen into the solution.

In MBRs the membrane separates the product water from the biomass, whereas in MABRs it enhances aeration of the mixed liquor
