New concepts in anammox processes for wastewater nitrogen ...

The discovering of anaerobic ammonium oxidation (anammox) process led to the development of autotrophic nitrogen removal systems for the treatment of effluents with low C:N rate. The anammox processes provide an efficient way to remove high concentrations of ammonium compounds from industrial and urban wastewater and covert them to dinitrogen.

Organic ,nitrogen, is released as ,ammonia nitrogen, when bacteria decompose organic matter. ,Ammonia, is lost as a gas or converted to nitrites, which are rapidly oxidized to nitrates by bacteria. Nitrates can be reduced back to ,ammonia, by bacterial reduction. This cycle continues unless retarded by a bacterial inhibitor.

Air stripping of ,ammonia, from anaerobic digestate has been reported to recover 70–92 % ,of nitrogen,. Membrane separation provides recovery in the order of 99–100 % with no secondary pollutant in the permeate.With regard to phosphorus (P) removal, physical filtration and membrane processes have the potential to reduce suspended P to trace amounts but provide minimal dissolved P removal.
