Nitrogen Removal from Wastewater by a Sequencing Batch Reactor
Sequencing batch reactor (SBR) is one of several periodically operated, suspended-growth activated sludge system. It has an advantage for nitrogen removal which is difficult to remove with conventional system. This paper reviewed the nitrogen removal performance in SBR for several different industrial wastewaters and discussed the factors which may affect the treatment performance. Several modi...
متن کاملevaluation of the efficiency of the sequencing batch reactor in nitrogen and phosphorus removal from synthetic wastewater in a bench scale experiment
background : the sequencing batch reactor (sbr) is one of the most widely used systems in sewage treatment because of the simplicity of the process, flexibility of operation in the removal of nutrients, and the ability to be used in different scales. the aim of this study was to evaluate the efficiency of the sbr in the removal of organic matter (nitrogen and phosphorus) from synthetic wastewat...
متن کاملRemoval of Nitrogen Compounds from Industrial Wastewater Using Sequencing Batch Reactor: The Effects of React Time
Abstract—This study was performed to optimise the react time (RT) and study its effects on the removal rates of nitrogen compounds in a sequencing batch reactor (SBR) treating synthetic industrial wastewater. The results showed that increasing the RT from 4 h to 10, 16 and 22 h significantly improved the nitrogen compounds’ removal efficiency, it was increased from 69.5% to 95%, 75.7 to 97% and...
متن کاملNitrogen removal in a Sequencing Batch Biofilm Reactor: effect of carbon availability and intermittent aeration
This study aimed to investigate the effects of carbon availability and intermittent aeration on nitrogen removal in a Sequencing Batch Biofilm Reactor (SBBR). The percentage of nitrogen removal in the SBBRs operating with dump fill and slow fill with optimum intermittent aeration was quite similar, 75.7% and 69.2%, respectively, indicating that intermittent aeration allowed a considerable energ...
متن کاملAssessment of nitrogen and phosphorus removal in an intermittently aerated sequencing batch reactor (IASBR) and a sequencing batch reactor (SBR).
Biological nitrogen and phosphorus removal was investigated in an intermittently aerated sequencing batch reactor (IASBR) and a sequencing batch reactor (SBR). The removal efficiencies of ammonium-nitrogen (NH4(+)-N) were 100% in both reactors in steady operation state. The total nitrogen (TN) removal efficiencies were 90.4% in the IASBR and 79.3% in the SBR, while the total phosphorus (TP) rem...
