Quinone electron shuttle enhanced ammonium removal performance in anaerobic ammonium oxidation coupled with Fe(III) reduction

Hongzhong Dang et al.

Summary: In this study, different iron sources were added to anaerobic sequencing batch reactors (ASBR) to investigate the effect of Feammox reaction on ammonium removal performance. The results showed that the removal efficiencies of ammonium in Fe2O3, Fe(OH)3 and Fe3O4 groups were 34.02%, 22.8% and 7.58% respectively. Additionally, AQDS was found to enhance the ammonium removal performance of Feammox, especially accelerating the electron shuttle rate between Fe2O3 and ammonium.

Feammox process driven anaerobic ammonium removal of wastewater treatment under supplementing Fe(III) compounds

Ting-ting Zhu et al.

Summary: The Feammox process plays a crucial role in the natural nitrogen cycle, but has been rarely investigated in the field of wastewater treatment. This study explored the potential of anaerobic ammonium removal coupled with organics to assess the Feammox process for conventional wastewater treatment. Results showed that the Fe2O3 group had the highest efficiency in ammonium removal, while organics significantly inhibited the Feammox process.

Fe(III)-mediated anaerobic ammonium oxidation: A novel microbial nitrogen cycle pathway and potential applications

Xin Tan et al.

Summary: Feammox is a novel pathway for ammonium (NH4 (+)) oxidation and nitrogen cycle, leading to significant loss of nitrogen in natural environments. Various Feammox pathways, end products, and interactions within microbial communities have been revealed by researchers, offering alternative processes for wastewater treatment. However, substantial variations exist among different studies in terms of key functional microorganisms.

Responses of anammox process to elevated Fe(III) stress: Reactor performance, microbial community and functional genes

Shaoqing Zhang et al.

Summary: The study indicates that long-term exposure to low concentration Fe(III) can improve the nitrogen removal efficiency of the anammox process, while high Fe(III) concentrations deteriorate reactor performance. Different functional bacteria show varied responses to Fe(III) stress, with high concentrations of Fe(III) significantly altering the anammox community structure.

A promising destiny for Feammox: From biogeochemical ammonium oxidation to wastewater treatment

Jiaxuan Zhu et al.

Summary: Ammonium is a common form of nitrogen in wastewater, and new technologies are needed to effectively remove it to prevent severe pollution. Feammox, known as anaerobic ammonium oxidation coupled to Fe(III) reduction, is an efficient and environmentally friendly method that can be combined with other nitrogen removal reactions for wastewater treatment.

Nitrogen Removal by an Anaerobic Iron-Dependent Ammonium Oxidation (Feammox) Enrichment: Potential for Wastewater Treatment

Carolina Rodriguez et al.

Summary: This study focused on the Feammox mechanism in activated sludge obtained from a sewage treatment plant, showing that FeCl3 was more effective as an iron source for the oxidation of NH4+ and the reduction of Fe(III) to Fe(II). The research provides valuable information on the potential of Feammox in removing N from wastewater and the oxidation/reduction yields in the initial enrichment phase.
