Undissociated HNO 2  (up to 2 mg dm −3 ) was confirmed as substrate inhibitor for granular biomass from a denitritation upflow sludge bed reactor used for biological removal of nitrite. On the contrary, total nitrite nitrogen (N-NO 2  up to 500 mg dm −3 ) and methanol (COD up to 2000 mg dm −3 ) were not proven to be inhibitors. pH also affected the denitritation efficiency (optimal pH was 5.9). Reduction of HNO 2  concentration in the reactor by effluent recycling is recommended.
