  • How much ammonium nitrogen can be discharged into a wastewater treatment plant?
  • More stringent discharge limits of ammonium nitrogen have been gradually enforced for wastewater treatment plants (WWTPs) (Wang et al., 2006). For instance, ammonia nitrogen's discharge standard into surface water is 17 mg/L in the US, 1.5–10 mg/L in the European Union, and 1.5–5 mg/L in China.
  • How to remove ammonia nitrogen from industrial wastewater?
  • However, the ammonia–nitrogen concentration in industrial wastewater is generally high. Based on this, air stripping might be the preferred ammonia–nitrogen removal method for industrial wastewater. The acid adsorption of the stripping gas can recover ammonia nitrogen (Yin et al. 2018b).
  • Why is ammonia–nitrogen recovery important in wastewater treatment & water purification?
  • The recovery of ammonia–nitrogen during wastewater treatment and water purification is increasingly critical in energy and economic development. The concentration of ammonia–nitrogen in wastewater is different depending on the type of wastewater, making it challenging to select ammonia–nitrogen recovery technology.
  • Are nitrogen removal technologies applied in the reject water treatment?
  • This review critically assesses nitrogen removal technologies applied in the reject water treatment, across different stages of technological development, with a focus on their economic and environmental impacts. The prevalent use of biological processes raises concerns due to potential environmental impacts caused by N 2 O emissions.
