Journal ArticleDOI
Mainstream partial nitritation-anammox in municipal wastewater treatment: status, bottlenecks, and further studies.
TL;DR: This review paper provides an overview of the current state of research and development of mainstream PN/A process and critically analyzes the bottlenecks for its full-scale application.
Journal ArticleDOI
Influence of temperature and pH on the anammox process: A review and meta-analysis.
TL;DR: This paper presents a comprehensive study of the most important and recent findings on the influence of two parameters that are crucial in wastewater treatment, i.e. temperature and pH.
Journal ArticleDOI
Technologies for biological removal and recovery of nitrogen from wastewater.
TL;DR: An overview of various technologies of biological nitrogen removal including nitrification, denitrification, anaerobic ammonium oxidation (anammox), as well as bioelectrochemical systems and microalgal growth for nitrogen recovery are presented.
Journal ArticleDOI
Achieving high-level nitrogen removal in mainstream by coupling anammox with denitrifying anaerobic methane oxidation in a membrane biofilm reactor.
TL;DR: Fluorescence in situ hybridization and 16S rRNA gene sequencing indicated that anammox bacteria, DAMO bacteria and DAMO archaea jointly dominated the biofilm, and were likely the key contributors to nitrogen removal.

Uncoupling the solids retention times of flocs and granules in mainstream deammonification: A screen as effective out-selection tool for nitrite oxidizing bacteria
Mofei Han,Siegfried E. Vlaeminck,Siegfried E. Vlaeminck,Ahmed Al-Omari,Bernhard Wett,Charles Bott,Sudhir Murthy,H. De Clippeleir +7 more
TL;DR: This study focused on a physical separator in the form of a screen to out-select nitrite oxidizing bacteria (NOB) for mainstream sewage treatment and achieved an effluent total nitrogen concentration <10mgN/L using this novel approach combining biological selection with physical separation.

Inhibition of nitrification by ammonia and nitrous acid
TL;DR: The importance of NITRIFICATION has been recognized for more than a hundred years and engineers and scientists continue to investigate the process to obtain a better understanding of the fundamentals and to use the process for the benefit of man.
Journal Article
Inhibition of nitrification by ammonia and nitrous acid.
TL;DR: Control nitrification may occur during waste treatment, and engineers have begun to incorporate the process as part of nitri fication-denitrification systems for nitrogen control preceding discharge of the treated wastes.

Evaluation of activity and inhibition effects on Anammox process by batch tests based on the nitrogen-gas production
A. Dapena-Mora,Isaac Fernández,José Luis Campos,Anuska Mosquera-Corral,Ramón Méndez,Mike S. M. Jetten +5 more
TL;DR: In this paper, the authors focused on the application of batch tests to determine the maximum specific Anammox activity (SAA) of different compounds commonly present in industrial effluents.
