Abstract

Background: Various chemical, physical and biologic treatment methods are being used to remove nitrogen and PHOSPHORUS from WASTEWATER. Sequencing batch reactor (SBR) is a modified activated sludge process that removes PHOSPHORUS and organic material from sanitary WASTEWATER, biologically.Methods: This study was conducted in 2016.The performance of an aerobic-anaerobic SBR pilot device, located at Ahwaz West WASTEWATER Treatment Plant, Ahwaz, southern Iran in PHOSPHORUS and organic material removal was evaluated to determine the effect of the aerobic-anaerobic step time on the efficiency of nitrogen and PHOSPHORUS removal, the effect of changing the sequence of steps and the effect of time ratio on PHOSPHORUS removal efficiency. A reactor of 8 L was used. Influent contained 397 and 10.7 mg/l COD and PHOSPHORUS, respectively. The pilot plant started with a 24 h cycle including four cycles of 6 h, as follows: 1- Loading (15 min), 2-Anaerobic (2 h) -Aerobic (2 h), 3- Settling (1 h), Idleness (30 min) and 5- decant (15 min).Results: After reaching steady conditions (6 months), Removal percentages of PHOSPHORUS, BOD5, COD, and TSS in The SBR over a period of 6 months was 79%, 86%, 89% and 83%, respectively.Conclusion: Result of this study can be used for designing and optimum operation of sequencing batch reactors.
