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 کاملEffect of nitrite from nitritation on biological phosphorus removal in a sequencing batch reactor treating domestic wastewater.
Although nitrite effect on enhanced biological phosphorus removal (EBPR) has been previously studied, very limited research has been undertaken about the effect of nitrite accumulation caused by nitritation on EBPR. This paper focused on nitrite effect from nitritation on EBPR in a sequencing batch reactor treating domestic wastewater. Results showed that nitrite of below 10mg/L did not inhibit...
متن کاملMoving Bed Biofilm Reactor Performance in Phenol Removal from Wastewater
Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...
متن کاملNitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification Using a Biofilm Filtration Reactor
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients and harmful effects on down-stream in the livestock manure process with respect to the microbial growth. Simultaneous nitrification and denitrification (SND) is linked to inhibition of the second ni...
