About this Research Topic
One of the common and toxic compounds of nitrogen is ammonia, and contamination of ammonia in waterways has lately become one of the greatest environmental issues. Amongst biological treatment ways for removal of nitrogen from waterways, anaerobic ammonium oxidation (anammox) has gained researchers’ attention. Anammox is a biological procedure capable of anaerobic conversion of NH4+ to dinitrogen (N2) gas with NO2 as an electron acceptor. The anammox process has been demonstrated to be a better substitute for conventional techniques because the utilization of anammox bacteria in wastewater treatment diminishes the energy utilization of wastewater treatment plants since without the supply of oxygen almost 45% of the influent ammonium might be oxidized anoxically.
In this Research Topic, we would like to improve our understanding of anammox processes in removing nitrogen. Remarkably, anammox does not show a good performance with respect to other kinds of pollutants. High nitrogen concentrations and other toxic conditions, such as high amount of chemical oxygen demand (COD), and metals in wastewaters limit treatment by anammox. The goal is to get an overview of which factors promote the anammox process. In this context, we are eager to learn how to employ anammox process directly in treating water and wastewater with high amount of pollutants.
This Research Topic seeks original research and review manuscripts on anaerobic ammonium oxidation applied to the treatment of water, industrial and domestic wastewater, and sludge. The potential areas to be covered in this Research Topic may include, but are not limited to:
• Anammox applications
• Co-occurrence of denitrification and anammox
• Competition or reaction between anammox, and other bacteria
• Identification of novel players in anammox process
• Hybrid reactors including anammox
• Improving resistance of anammox against other contaminants
• Improving growth of anammox in a shorter time.
