Feammox bacterial biofilm formation in HFMB.

Nitrogen pollution has been increasing with the development of industrialization. Consequently, the excessive deposition of reactive nitrogen in the environment has generated the loss of biodiversity and eutrophication of different ecosystems. In 2005, a Feammox process was discovered that anaerobically metabolizes ammonium.

Coupling of the Feammox - Anammox pathways by using a sequential discontinuous bioreactor.

Treating nitrogenous compounds in wastewater is a contemporary challenge, prompting novel approaches for ammonium (NH) conversion to molecular nitrogen (N). This study explores the classic anaerobic ammonium oxidation process (Anammox) coupled to the iron-dependent anaerobic ammonium oxidation process (Feammox) in a sequential discontinuous bioreactor (SBR) for NH removal. Feammox and Anammox cultures were individually enriched and combined, optimizing the coupling, and identifying key variables influencing the enrichment process.

Study of the key biotic and abiotic parameters influencing ammonium removal from wastewaters by Fe-mediated anaerobic ammonium oxidation (Feammox).

The release of ammonia (as NH) into water bodies causes serious environmental problems. Therefore, the removal of ammonia from wastewater effluents has become a worldwide concern. New autotrophic biological alternatives for ammonia removal could reduce the limitations of conventional organic carbon-dependent nitrification-denitrification methods.

Life cycle assessment of greywater treatment systems for water-reuse management in rural areas.

Water scarcity is a major concern worldwide. Population growth, as well as the intensive use of water resources for industrial and agricultural activities, among others, have caused water stress in various regions of the world. Rural areas are usually more affected due to water scarcity and a lack of sanitary infrastructure.
