N2O-production was investigated during nitrogen removal using aerobic granular sludge (AGS) technology. A pilot sequencing batch reactor (SBR) with AGS achieved an effluent in accordance with national discharge limits, although presented a nitrite accumulation rate of 95.79% with no simultaneous nitrification-denitrification. N2O production was 2.06 mg L-1 during the anoxic phase, with N2O emission during air pulses and the aeration phase of 1.6% of the nitrogen loading rate. Batch tests with…

Sulfur-based denitrification may be a key biogeochemical nitrate (NO3 −) removal process in sulfide-rich regions, but it is still poorly understood in natural terrestrial ecosystems. We examined

Microbial pathways of nitrogen removal in aerobic granular sludge treating domestic wastewater

BACKGROUND Aerobic granular sludge (AGS) technology has been widely investigated for wastewater treatment. The morphological and structural characteristics of granules and nitrogen pathways have not
