Nitrogen removal and microbial community responses in anammox-enhanced biofilters across diverse urban waters.
Biofilters offer decentralized nitrogen treatment but often show variable performance across influent types. This study evaluated anammox-enhanced biofilters (A-BF, inoculated with enriched anammox biomass) and control biofilters (C-BF) treating wastewater (WW), stormwater (SW), and greywater (GW) under synthetic and r...
