“Enrichment and adaptation yield high anammox conversion rates under low temperatures”. De Cocker P, Bessiere Y, Hernandez-Raquet G, Dubos S, Mozo I, Gaval G, Caligaris M, Barillon B, Vlaeminck SE, Sperandio M, Bioresource technology 250, 505 (2018). http://doi.org/10.1016/J.BIORTECH.2017.11.079
Abstract: This study compared two anammox sequencing batch reactors (SBR) for one year. SBRconstantT was kept at 30 °C while temperature in SBRloweringT was decreased step-wise from 30 °C to 20 °C and 15 °C followed by over 140 days at 12.5 °C and 10 °C. High retention of anammox bacteria (AnAOB) and minimization of competition with AnAOB were key. 5-L anoxic reactors with the same inoculum were fed synthetic influent containing 25.9 mg NH4+-N/L and 34.1 mg NO2−-N/L (no COD). Specific ammonium removal rates continuously increased in SBRconstantT, reaching 785 mg NH4+-N/gVSS/d, and were maintained in SBRloweringT, reaching 82.2 and 91.8 mg NH4+-N/gVSS/d at 12.5 and 10 °C respectively. AnAOB enrichment (increasing hzsA and 16S rDNA gene concentrations) and adaptation (shift from Ca. Brocadia to Ca. Kuenenia in SBRloweringT) contributed to these high rates. Rapidly settling granules developed, with average diameters of 1.2 (SBRconstantT) and 1.6 mm (SBRloweringT). Results reinforce the potential of anammox for mainstream applications.

“Short and long term effect of decreasing temperature on anammox activity and enrichment in mainstream granular sludge process”. De Cocker P, Bessiere Y, Hernandez-Raquet G, Dubos S, Mercade M, Sun XY, Mozo I, Barillon B, Gaval G, Caligaris M, Ruel SM, Vlaeminck SE, Sperandio M, Frontiers In Wastewater Treatment And Modelling, Ficwtm 2017 4, 50 (2017). http://doi.org/10.1007/978-3-319-58421-8_8
Abstract: This study investigates the impact of lower temperature on short term and long term (down to 10 degrees C) on a completely anoxic anammox granular sludge process. This is the first time granular sludge Anammox is operated in pure anoxic condition in SBR and at low temperature. Conversion performance, kinetic parameters, sludge characteristics and microbial community were analyzed.
