Conventional ammonia removal from wastewater comes in two forms: The first, and most commonly employed method, is the use of bacteria in aerated or anoxic reactors. For waste-water streams with relatively low ammonia and comparatively high carbon loading, it has proven to be a robust, viable and long-term solution. Difficulties only arise when the carbon available in the wastewater is not adequate to drive the necessary conversions to nitrogen gas. When a wastewater stream has very high ammonia levels (greater than 3000 mg/l) and carbon is inadequate, the cost of operation for an extended duty-of-care period can become excessive.

Thermally-driven ammonia stripping was developed by Organics to offer an alternative route to that of pH adjustment for continuous-process ammonia stripping. With a thermally-driven stripper no chemical additions are required, apart from the minor addition of anti-foam agent.
