  • 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.
  • Does Brazil have a good sanitation system?
  • Brazil is marked by poor access to sanitation services, which includes both wastewater collection and treatment. According to data from the National Sanitation Information System (SNIS) published in 2025 [ 13 ], the country collected an average of 55.8% of the wastewater produced in the country ( Figure 2 ), of which only 51.2% was treated.
  • 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).
  • Are ammonia treatment technologies effective?
  • To date, majority of ammonia treatment technologies achieved high removal efficiencies; however, most of these technologies have been evaluated on laboratory scale and this has progressed significantly in addressing or eliminating limiting factors associated with ammonia removal and they include cost, energy, and formation of by-products.
