Simultaneous nitrification-denitrification in a fluidized bed reactor
Water Science and Technology, 1998 This paper describes simultaneous nitrification-denitrification (SND) in a fluidized bed reactor (FBR) without physical separation of the aerobic and anoxic zones. Continuous reactor SND trials demonstrated successful SND over distinct periods. Control was achieved by varying the reactor dissolved oxygen and the feed COD, although optimal performance ...

Study of factors affecting simultaneous nitrification and denitrification (SND)
Water Science and Technology, 1999 Experiments have been performed to gain an understanding of the conditions and processes governing the occurrence of SND in activated sludge systems. Sequencing batch reactors (SBRs) have been operated under controlled conditions using the wastewater from the first anaerobic pond in an abattoir wastewater treatment plant.
