“…The SBR technology, despite its simplicity as a batch reactor, offers a great flexibility of operation where the sequence of successive phases can be adjusted to sustain any desired combination of growth conditions for different biochemical processes (Irvine et al, 1997;Ketchum, 1997;Morgenroth and Wilderer, 1998). This feature is particularly significant for simultaneous nitrogen and phosphorus removal, now a prerequisite for most wastewaters.…”

Performance of sequencing batch reactors for simultaneous nitrogen and phosphorus removal is evaluated by means of model simulation, using the activated sludge model, ASM2d, involving anoxic phosphorus uptake, recently proposed by the IAWQ Task group. The evaluation includes all major process configurations with different aerobic, anoxic, anaerobic sequences, and fill conditions. Basic relationships between modelling and design based on overall process stoichiometry are established for the interpretation of nutrient profiles associated with different operation modes. A similar approach is also used for the assessment of the effect of major operating parameters on system performance.

“…The SBR was not only used efficiently for organic pollutants removal of municipal wastewater, but also successfully applied in the nitrogen removal of wastewater (Silverstein and Schroeder, 1983). Microbial reactions of nitrogen removal are performed within the same SBR tank (Ketchum et al, 1997;Gali et al, 2008). It can also be applied for pollutants removal of wastewater containing a high concentration of nitrogen and organic matters (Rodríguez et al, 2011).…”

Abstract. The objective of this study was to investigate the pollutant removal efficiency of different types of wastewaters by a sequencing batch reactor (SBR). A laboratory-scale SBR was used to treat sewage, medical wastewater and industrial wastewater. The effects of different conditions of aeration, stirring and settling on the efficiency of pollutants removal were explored to optimize the performance, especially for the removal of organic matter (COD), ammonia nitrogen (NH 4 + -N), total nitrogen(TN) and total phosphorus(TP) of different types of polluted water. From the results it was showed that when aeration 6 hours, stirring 4 hours and settling 2 hours in SBR, the removal rates of COD, nitrogen and phosphorus of domestic sewage were 93%, 98% and 83%, respectively; when aeration 5 hours, stirring 5 hours and settling 1 hour in the SBR, the removal rates of COD and nitrogen of pharmaceutical wastewater were 83% and 90%, respectively; when aeration 4 hours, stirring 4 hours and settling 1 hour in the SBR, removal rates of COD, nitrogen and phosphorus of industrial wastewater were 97%, 93% and 97%, respectively.
