Abstract A sequencing batch reactor (SBR) was used to remove phosphate in biological wastewater treatment as an alternative to the activated sludge process, in order to improve the low removal efficiency of phosphate and the operational instability. After a cycle of 2 h anaerobic and 4 h aerobic conditions, phosphate removal was optimized. The removal efficiencies of 5 and 50 mg phosphate l−1 by Staphylococcus auricularis under repeated anaerobic and aerobic conditions were above 90%. These results showed that a long adaptation time, one of the major problems in biological phosphate removal process, was overcome by SBR.
