Nitrifying population dynamics in a redox stratified membrane biofilm reactor (RSMBR) for treating ammonium-rich

Rongchang WANG, Xinmin ZHAN, Yalei ZHANG, Jianfu ZHAO

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 1,   Pages 48-56 doi: 10.1007/s11783-011-0305-7

Abstract: Nitrogen removal performance and nitrifying population dynamics were investigated in a redox stratified membranebiofilm reactor (RSMBR) under oxygen limited condition to treat ammonium-rich wastewater.Confocal micrographs showed the stratified distributions of nitrifiers and denitrifiers in the membrane, while heterotrophic bacteria propagated at the top of the biofilm.The growth of heterotrophic bacteria compromised the dominance of nitrifiers in biofilm communities,

Nitrogen removal performance of municipal reverse osmosis concentrate with low C/N ratio by membrane-aeratedbiofilm reactor

Xiao Quan, Kai Huang, Mei Li, Meichao Lan, Baoan Li

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 6, doi: 10.1007/s11783-018-1047-6

Abstract:

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio.

Operating conditions should be properly controlled to achieve optimal TN removal.

Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress.

The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.

Effects of carrier-attached biofilm on oxygen transfer efficiency in a moving bed biofilm reactor

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 3,   Pages 569-577 doi: 10.1007/s11783-015-0822-x

Abstract: Three laboratory-scale moving bed biofilm reactors (MBBR) with different carrier filling ratios rangingfrom 40% to 60% were used to study the effects of carrier-attached biofilm on oxygen transfer efficiencyThese results were compared to αSOTE of wastewater with a clean carrier (no biofilm attached).This indicated that the biofilm attached to the carrier had a negative effect on αSOTE.Biofilm flocs could decrease αSOTE by about 20%, and SMP could decrease αSOTE by 30%–50%.

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 1, doi: 10.1007/s11783-019-1097-4

Abstract:

SBBR-CW system was proposed to effectively treat wastewater containing TCBPA.

CW unit contributed more than SBBR to the removal of TCBPA.

TCBPA changed the composition and structure of bacterial community in the system.

GAOs massively grew in SBBR, but did not deteriorate TP removal efficiency.
