A further toxic compound located in water bodies is ammonia, and ammonia contamination in wastewater and water bodies happens to be A significant environmental trouble [12]. Many tactics are founded for the treatment of nitrogen. Between these procedures, anaerobic ammonium oxidation (anammox) has acquired researchers’ consideration for nitrogen removal uses.
