Mechanistic Understanding of the NOB Suppression by Free Ammonia Inhibition in Continuous Flow Aerobic Granulation Bioreactors
… mg N L-1 to verify that the upper range of total ammonia nitrogen (TAN) for domestic wastewater can supply an inhibitory level of free ammonia (FA) for nitrite oxidizing bacteria (NOB) suppression in CFRs at pH around 7.8. The ammonia oxidizing bacteria (AOB):NOB activity ratio was determined for …

Submerged-Membrane Bioreactor for the Treatment of NASA Wastewater
… biological nitrification proved difficult due to free ammonia inhibition, by acidifying reactor feed consistent nitrification was observed. An unexpected observation was nitrite accumulation, typically a transient species in wastewater treatment. Kinetic modeling suggests that nitrite accumulation …

Optimization of Phosphorus Removal and Mineral Characterization in Aerated Anaerobic Digestate with Divalent Cation Addition
… with no nitrification observed likely due to free ammonia inhibition. Alkalinity reduction exceeded predicted levels, suggesting additional coprecipitation reactions occurred. Aeration and mixing consistently achieved about 20 percent total COD removal across the pilot in microaerobic …
