There are following method to remove ammonia
1.Air stripping at elevateted pH(9.5-10.5)
2. Biological Treatment
3. Adsorption by Zeolite(Ion Exchange)
4. Use chemical like H2SO4 and then neutralise.
5. Distillation with steam
The general approach to ammonia removal would be primary and polishing softeners. Ammonia is removed preferentially to sodium by cation resin, but is displaced by calcium and magnesium. Therefore, a single softener will remove ammonia during the initial part of its cycle but will then release the ammonia as it becomes exhausted with hardness.
Softening can be used effectively for ammonia removal if the primary softener is allowed to load to a hardness endpoint and a polishing softener is used to remove ammonia. In this case, the primary softener must not be operated to hardness breakthrough, as this would cause an ammonia spike and lead to elevated ammonia levels in the final product water.

Air stripping is not a good idea, unless the ammonia gas is captured. Otherwise, you simply put the ammonia back into the terrestrial and aquatic environments via precipitation.
