Ammonia removal kinetics and solids' production performance of the bio-cord technology are studied in this research. Three nitrifying reactors housing different substratum were operated at five ammonia loading rates. All substrata demonstrated stable high ammonia-nitrogen efficiencies 96.8 ± 0.9%, 97.0 0.6% 92.0 0.4% rates 0.8, 1.6 1.8 g NH4+-N/m2 d, respectively. At these same rates, three also showed low 0.19 0.03, 0.23 0.02, 0.25 0.03 total suspended solids/d. A reduction system...
Abstract In this study, a municipal lagoon with high wintertime effluent total ammonia nitrogen (TAN) concentrations was upgraded pilot‐scale nitrifying‐nitrifying‐denitrifying (NIT‐NIT‐DENIT) moving bed biofilm reactor (MBBR) treatment train to characterize its over operation, investigate the feasibility of upgrading lagoons achieve substantial biological removal across ultra‐low temperatures (0.6–3.0) and nitrification inhibition pathways in facultative systems at temperatures. Throughout...

The cold-shocked system, rapidly cooled from 10 °C to 1 °C, was characterized by lower nitrification kinetics and differences in biomass microbiome responses compared an acclimatized system operated parallel allowed acclimatize.
