Anammox bacteria in sludge from an anoxic tank of a municipal wastewater treatment plant at Nongkhaem, Bangkok, Thailand were enriched in two sequencing batch reactors (SBRs; SBR-1 and SBR-2), under different conditions. SBR-1 was open to the atmosphere, while SBR-2 was closed and flushed with a mixture of 95% argon and 5% CO(2) during the fill period in order to provide strict anaerobic conditions. The specific nitrogen removal rates of SBR-1 and SBR-2 were 0.
