AEROBIC NITRITATION OF AMMONIA AND INTEGRATED ANAMMOX PROCESSES

AEROBIC NITRITATION OF AMMONIA AND INTEGRATED ANAMMOX PROCESSES

Processes are disclosed for the microbial nitritation of ammonia that attenuate the production of at least one of nitrate anion and nitrous oxide. The processes use an ME biocatalyst having a highly porous, hydrophilic polymeric structure with ammonia-oxidizing microorganisms substantially irreversi...

Zusammenfassung:Processes are disclosed for the microbial nitritation of ammonia that attenuate the production of at least one of nitrate anion and nitrous oxide. The processes use an ME biocatalyst having a highly porous, hydrophilic polymeric structure with ammonia-oxidizing microorganisms substantially irreversibly retained therein. The processes are particularly useful for integration with anammox processes.
