Long-term partial nitrification in an intermittently aerated sequencing batch reactor (SBR) treating ammonium-rich wastewater under controlled oxygen-limited conditions
Highlights Development of a novel technology for partial nitrification at ambient temperature. First time to use online NH4-–N measurement as a control parameter for bioreactors. RT-PCR analysis shows the population size of AOB was up to 10% of total bacteria. Intermittent aeration and oxygen-limited conditions sustained partial nitrification. The bioreactor …
