“…With an attractive application, this bacterial process, which has been demonstrated to be a budgetfriendly and highly efficient wastewater treatment method, has drawn a lot of interest. Nitrite (NO2) is reduced to nitrogen gas (N2) via the Anammox process [25], using ammonium (NH4 + ) as the electron donor [26,27]. However, ensuring both the maintenance and improvement of stability and optimal efficiency in the Anammox process are crucial factors in the advancement of carbonneutral wastewater treatment facilities [28].…”

“…In the Anammox process, nitrite and ammonium ions are immediately converted to diatomic nitrogen and water. Anammox is a globally important nitrogen cycle microbial process that occurs in a variety of natural environments [26,32]. The application of Anammox in urban wastewater systems has the potential of optimizing energy recovery by redirecting organic carbon from the nitrogen removal process and redirecting it towards anaerobic digestion.…”

“…The biological coupling approach, which involves the integration of Anammox with denitrification, has attracted significant attention in the past decade due to its potential for achieving high nitrogen removal efficiency [53,54]. The equations ( 2) and (3) depict the primary processes that take place in the Combined Partial Nitritation and Anaerobic Ammonium Oxidation (CPNA) process.…”

An upsurge in living standards, rising industrialization and urbanization, the protection of water environment has become a priority. Anaerobic ammonium oxidation process has drawn a lot of attention since it demonstrated substantial advantages over conventional nitrogen removal techniques, including a 100% reduction in the amount of organic carbon required, a 60% reduction in the amount of aeration needed, and a 90% reduction in the amount of sludge produced. Effective treatment of landfill leachate is extremely important as leachate is a threat to the environment. Municipal waste management is still a challenging situation in developing countries. Uncontrolled waste disposal results in greenhouse gases emissions which worsens climate change as the leachate will pollute water bodies, soil and a significant air pollution which impacts on human health will be released. This paper reviewed several published research works in Scopus dealing with the leachate treatment by Anammox process combined with some other systems and highlighted some common challenges found with the application of this new technology. Treating landfill leachate resulted in an excellent ammonium NH4 +-N removal efficiency. However, it has been highlighted that most of the research reviewed reported some limitations of the technology on a small scale such as the low start-up time affecting the growth of bacteria in the reactors and the instability of the system when pH and temperature decrease. Biological treatment, Anammox method included, offers a cost-effective, eco-friendly, and an effective solution for nitrogen removal.
