Optimizing anoxic biological phosphorus removal in the anaerobic-anoxic sequencing batch reactor (A(2) SBR) was observed to depend on two parameters: the amount of added nitrate and the sludge retention time (SRT). The concentration of 120 mg N-NO3 . l(-1) in the anoxic medium and the SRT of 16 days were determined as optimal for a complete phosphorus removal in the A, SBR. The reactor was supplied with synthetic wastewater containing 800 mg COD.I-1 acetic acid, 240 mg N-NH4 . I-1 and 30 mg P-PO4 . l(-1). This study was completed by microscopic observations which revealed three morphological types of phosphate-accumulating bacteria (PAB).
