  • What is nitrogen-rich wastewater?
  • 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.
  • How to remove nitrogen from wastewater?
  • Many different processes have been studied in available literature to remove nitrogen from wastewater. These treatment processes can be classified as chemical, physical, and biological methods, and they are often selected based on many advantages such as high selective separation, simplicity in control, and lower space requirement.
  • What are the different types of Wastewater nitrogen removal methods?
  • Nowadays, the main wastewater nitrogen removal methods can be divided into physical, chemical, and biological processes . Physical treatment methods, such as ammonia stripping, ion exchange, and adsorption [10, 11, 12], have high retention rates for organic pollutants .
  • Can nitrification be used to remove nitrogen from wastewater?
  • For many years, the traditional biological method for nitrogen removal from wastewater has been the combination of nitrification and denitrification processes. Frequently, space limitations or economic constraints do not allow the capacity of the existing treatment plants, especially for wastewater with a high ammonium load, to be expanded [ 2 ].
