Assessment 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...
متن کاملNitrogen 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 کاملCharacteristics of MEG Removal from Industrial Wastewater by Sequencing Batch Reactor (SBR)
Background: MEG is extensively applied in the sour gas industry as a hydrate inhibitor. It is toxic in oral drinking and serious injury or death may result from swallowing of pure ethylene glycol and poses a potential hazard to the environment through impact soil. Glycols are harmful to aquatic life. There is little information about the digestion of MEG in the aerobic reactor. Therefore, t...
متن کاملRemoval of veterinary antibiotics from sequencing batch reactor (SBR) pretreated swine wastewater by Fenton's reagent.
The large-scale application of veterinary antibiotics in livestock industry makes swine wastewater an important source of antibiotics pollution. This work investigated the degradation of six selected antibiotics, including five sulfonamides and one macrolide, by Fenton's reagent in swine wastewater pretreated with sequencing batch reactor (SBR). The dosing mode and practical dosage of Fenton's ...
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...
