AB  - The processes of nitritation and full nitrification of synthetic reject 
      wastewater were compared in terms of N2O and NO emissions. Two lab-scale 
      sequencing batch reactors (SBR1 and SBR2) were enriched with Nitrosomonas 
      (ammonia-oxidizing bacteria) and Nitrobacter (nitrite-oxidizing bacteria), as 
      shown by fluorescence in situ hybridization (FISH) and high-resolution 16S rRNA 
      tag pyrosequencing. Stable conversion of ammonium to nitrite and nitrite to 
      nitrate was achieved in SBR1 and SBR2 respectively. Biomass from SBR2 was added 
      in SBR1 in order to achieve full nitrification. Under nitritation, 1.22% of the 
      converted-N was emitted as N2O, and 0.066% as NO. During the transition from 
      nitritation to full nitrification, effluent nitrite concentrations decreased but 
      nitrogen oxides were emitted at levels similar to the nitritation period. Gas 
      emissions decreased sharply under full nitrification conditions (0.54% 
      N2O-N/converted-N; 0.021% NO-N/converted-N), probably as a result of the combined 
      effect of lower nitrite and ammonium concentrations in the bioreactor.
