Nitrogen removal mechanisms in improved hybrid activated sludge-membrane aerated biofilm reactor: Insights from metagenomics and metaproteomics.
Simultaneous nitrification-denitrification (SND) is a promising process for low C/N wastewater treatment. A hybrid activated sludge-membrane aerated biofilm reactor (H-MABR) capable of achieving two‑stage SND was developed and exhibited satisfactory nitrogen removal performance; however, the underlying mechanisms remai...
