High-efficiency simultaneous ammonia and nitrate removal in iron-sulfur coupled system under carbon limitation: Multi-omics insights into metabolic regulation and microbial interactions.

Iron‑sulfur coupling is a promising process for efficient nitrate removal, but its potential for simultaneous ammonia removal remains poorly recognized. This study established a biofilter (ISBF) using sponge iron and elemental sulfur as mixed fillers. Over 228 days of operation, ISBF achieved excellent nitrate (98.1%)...
