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 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 کاملBiological nutrient removal by a sequencing batch reactor (SBR) using an internal organic carbon source in digested piggery wastewater.
Experiments in a lab-scale SBR were conducted to demonstrate the feasibility of using an internal carbon source (non-digested pig manure) for biological nitrogen and phosphorus removal in digested piggery wastewater. The internal C-source used for denitrification had similar effects to acetate. 99.8% of nitrogen and 97.8% of phosphate were removed in the SBR, from an initial content in the feed...
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 anaerobically digested swine wastewater using an intermittently aerated sequencing batch reactor.
A lab-scale intermittently aerated sequencing batch reactor (IASBR) was applied to treat anaerobically digested swine wastewater (ADSW) to explore the removal characteristics of veterinary antibiotics. The removal rates of 11 veterinary antibiotics in the reactor were investigated under different chemical organic demand (COD) volumetric loadings, solid retention times (SRT) and ratios of COD to...
