Coupling sulfur-based denitrification with anammox for effective and stable nitrogen removal: A review.

Water Research, 2022
Anoxic ammonium oxidation (anammox) is an energy-efficient nitrogen removal process for wastewater treatment. However, the unstable nitrite supply and residual nitrate in the anammox process have limited its wide application.

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 in Wastewater Treatment

2021
Water 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.

Robustness of the anammox process at low temperatures and low dissolved oxygen for low C/N municipal wastewater treatment.

Water Research
Low water temperatures and ammonium concentrations pose challenges for anammox applications in the treatment of low C/N municipal wastewater. In this study, a 10 L-water bath sequencing batch reactor combing biofilm and suspended sludge was designed for ...
