Highlights

•

Upflow membrane aerated biofilm reactor can treat low-strength nitrogen.

•

Nitritation–anammox is developed by gradually decreasing nitrite input.

•

The system achieves more than 80% removal of total nitrogen.

•

The observed NO3−–N/NH4+–N ratio of 8% is below the “theoretical ratio” (13%).

•

Anammox bacteria are dominant in granules and Candidatus Jettenia is the primary genus.
