Visual evidence for anammox granules expanding their size by aggregation of anammox micro-granules
Science of The Total Environment, 2020Granular sludge is superior in sustainable wastewater treatment; however, no consensus has achieved in its formation mechanism. In this study, we provide visual and experimental evidences to reveal how the large anammox granules formed. Micro-observation of anammox granules illustrated that some special anammox granules were clearly composed of ...

Today one of the most important environmental problems in the world is the proliferation of wastewater. The nitrogen is an important component that can be found in a wide range of concentrations and chemical forms. In the last decades, the nitrogen cycle has been re-evaluated, thanks to the anammox bacteria discovery.

Effects of oxytetracycline on anammox activity
Journal of Environmental Science and Health, Part A, 2012Batch experiments were conducted to investigate the effects of oxytetracycline on anaerobic ammonium oxidation (anammox) process. The short-and long-term effects on anammox activity were studied by measuring ammonium (NH(4)(+)), nitrite (NO(2)(-)), and nitrate (NO(3)(-)) concentrations over time.

Application of anammox based processes is nowadays an efficient way to remove nitrogen from wastewaters, being good alternative to the conventional nitrification-denitrification process. This chapter reviews the possible configurations to apply the anammox process, being special attention to the previous partial nitritation, necessary to obtain the ...

ANAMMOX in Wastewater Treatment
2021Water is a universal solvent that is used both for domestic and commercial purposes. Used water is referred to as wastewater which is released in a varying quantity of volumes to the environment. Wastewater could be point source or non-point source. This water consists of wastes, solid, liquid and gaseous.

The anammox house: On the extracellular polymeric substances of anammox granular sludge
2020In biofilms, microorganisms are embedded in a hydrated matrix that provides a stable structure and protection against influences fromthe environment. Thismatrix is formed by extracellular polymeric substances (EPS) that are produced by the microorganisms of the biofilm.

The stable nitrite (NO2--N) generation and rapid startup of anammox-based process are the main bottlenecks hindering its application in mainstream municipal wastewater treatment. In this study, a Partial-Denitrification (PD) system reducing nitrate (NO3--N) to NO2--N was rapidly developed within 40 days, using the nitrification/denitrification sludge ...

Partial nitritation/anammox (PN/A) has been recognized as a cost-efficient process for wastewater nitrogen removal. The addition of carriers could help achieve biomass retention and enhance the treatment efficiency by forming the dense biofilm. However, accurately determining the abundance of anammox bacteria (AnAOB) to evaluate the biofilm development

Nitrite oxidizing bacteria (NOB) outcompeting anammox bacteria (AnAOB) poses a challenge to the practical implementation of the partial nitrification/anammox (PN/A) process for municipal wastewater. A granules-based PN/A bioreactor was operated for 260 d with hydroxylamine (NH2OH) added halfway through.
