These results suggested that the DO concentration in influent to anammox reactor must be less than 2.5 mg/L. So far, anammox bacteria have not yet been purified from cultures. Some nitrogen-removing microorganisms cooperate to perform the anammox process. The objective of this research was to analyze the abundance and diversity of nitrogen-removing microorganisms in an anammox reactor Both reactors were filled, to 50% of their volume, with Kaldnes ring as a biofilm carrier. The influent supernatant, from dewatering of the digested sludge at the Himmerfjarden WWTP, was continuously pumped to the first reactor and next the Anammox reactor was fed with effluent from the first step. Microbial Aggregate and Functional Community Distribution in a Sequencing Batch Reactor with Anammox Granules. anammox-based granular sludge reactor affects the conversion--implications for modeling. Anammox has shown its promise and low cost for removing nitrogen from high strength wastewater such as landfill leachate. 8. anammox reactor. 8. loading rate. 8. reactor. 6. anammox. 5. high stable.

Moreover, to evaluate long-term anammox activity at moderately low temperatures, ABF reactors were operated for 446 d. Anammox activity could be maintained at 20-22 degrees C, and stable nitrogen removal performance was The anammox reactor type employed in Rotterdam was compared to other reactor types for the anammox process. Reactors with a high specific surface area like the granular sludge reactor employed in Rotterdam provide the highest volumetric loading rates. laboratory-scale stable partial nitrification-Anammox aquaculture water reactors by Liu Rong-rong, Wu Chun-du, and Lu Xu-jie J Water Reuse Desalination Volume 6(3):445-453 September 15, 2016 ©2016 by IWA Publishing Schematic diagram of the PN-Anammox reactor. A continuously fed bubble column granular sludge anammox reactor was operated for 405 days to investigate the effect of organic Results showed that influent COD improved the nitrogen removal of the anammox reactor at low influent COD/TN ratios (ca. Supplementary information PDF (520K). AOB and anammox activities were maximum at pH of 8.0 and 7.8-8.0, respectively. Short term effect of nitrite on anammox activity was studied Molecular analysis showed the nitritation-anammox sludge harbored a high microbial diversity, where each microorganism has a specific role. Our results illustrate the relationship between Anammox reactor performance and microbial community succession. The reactor was seeded with 300 mL of activated Anammox sludge taken from a lab-scale Anammox-UASB reactor in our laboratory and stored at 4 °C for 6 months.
