Rapid enrichment of anammox bacteria and transformation to partial denitrification/anammox with nitrification/denitrification sludge

Science of The Total Environment, 2023
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 ...

Linking morphological features to anammox communities in a partial nitritation and anammox (PN/A) biofilm reactor

Journal of Environmental Management, 2023
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

Anammox Growth on Pretreated Municipal Wastewater

Environmental Science & Technology, 2014
Autotrophic nitrogen removal from municipal wastewater enables development of energy autarkic wastewater treatment plants. In this study we report the evaluation of the anammox process in a granular sludge fluidized bed lab-scale reactor continuously fed with the actual effluent of the A-stage of the WWTP of Dokhaven, Rotterdam. The reactor was anoxic,

ANAMMOX PROCESS CONTROL BASED ON ANALYSIS OF ANAMMOX ACTIVATED SLUDGE METAGENOME

BIOTECHNOLOGY: STATE OF THE ART AND PERSPECTIVES, 2020
Based on the analysis of the metagenome of the community of activated sludge microorganisms that implements the process of anoxic oxidation of ammonia (Anammox), it was concluded that folate and formate should increase the stability and efficiency of the Anammox process, which was confirmed in the course of this work.

Microstructure and granulation cycle mechanisms of anammox-HAP coupled granule in the anammox EGSB reactor

Water Research, 2022
The formation of anammox-hydroxyapatite (HAP) coupled granules has been shown to be an approach to efficient nitrogen removal and phosphorus recovery in the anammox EGSB reactor. However, the granulation cycle mechanism of anammox-HAP coupled granules for sustainable regeneration and growth is still not well understood.

Anammox granule destruction and reconstruction in a partial nitrification/anammox system under hydroxylamine stress

Journal of Environmental Management, 2023
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.

[Enrichment regulation of anammox bacteria in the anammox start-up process].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2015
To study the enrichment regulation of anammox bacteria during the whole start-up process of anammox reaction, two reactors with addition of carries of Spherical Plastic (SP) and Bamboo Charcoal (BC) and one without carrier (CK) were used to start anammox reaction. Then FISH and q-PCR analyses for the growth of all anammox bacteria were conducted during

Nitrogen management in landfill leachate: Application of SHARON, ANAMMOX and combined SHARON–ANAMMOX process

Waste Management, 2012
In today's context of waste management, landfilling of Municipal Solid Waste (MSW) is considered to be one of the standard practices worldwide. Leachate generated from municipal landfills has become a great threat to the surroundings as it contains high concentration of organics, ammonia and other toxic pollutants.
