Wastewater Technology Fact Sheet: Ammonia Stripping

Ammonia stripping works well with wastewater that has ammonia contents between 10 to 100mg/l. For higher ammonia content (more than 100mg/l), it may be more economical to use alternate ammonia removal techniques, such as steam stripping or biological methods. Air stripping may also be used to remove many hydrophobic organic
