High concentrations of ammonia and nitrite, typical for reject water treatment in the anammox process with the use of high temperatures and pH, may cause free ammonia (FA) inhibition. In this study, the inhibitory effect of FA on anammox process rate was investigated in a bench-scale sequencing batch reactor (SBR) with granular anammox biomass. Results of the study present that the anammox process could be successfully operated at an FA concentration below 4 mgN•L-1. The anammox process rate decreased almost immediately when FA concentration increased up to 10.6 mgN•L-1. Short-term high concentrations of FA had no effect on the qualitative and quantitative composition of the anammox bacteria population.
