Nitrogen-rich wastewater is a major environmental issue that requires proper treatment before disposal. This comprehensive overview covers biological, physical, and chemical nitrogen removal methods. Simultaneous nitrification–denitrification (SND) most effective in saline water when utilizing both aerobic anoxic conditions with diverse microbial populations for removal. Coupling anammox denitrification could increase rates reduce energy demand. Suspended growth bioreactors effectively treated COD/N ratios demonstrated resilience to low C/N ratios. Moving biofilm exhibit reduced mortality rates, enhanced sludge–liquid separation, increased efficiency, stronger biological structures. SND studies show ≥90% total efficiency (%RETN) setups, Defluviicoccus, Nitrosomonas, Nitrospira as the main communities, while anammox–denitrification achieved %RETN of 77%. Systems using polyvinyl alcohol/sodium alginate medium showed ≥ 75%. Air-lift reflux configurations exhibited high %RENH4, reducing costs minimizing sludge formation. Microwave pretreatment high-frequency electric fields be used improve %RENH4. Adsorption/ion exchange, membrane distillation, ultrafiltration, nanofiltration promise industrial treatment. AOPs sulfate-based oxidants eliminate compounds from wastewater. Tailoring proposed treatments cost-effective removal, optimizing interactions, analyzing techno-economics emerging technologies are crucial.
