It can remove free ammonia only but cannot remove the dissolved or ionized forms of ammonia.

Except from regular used processes like ion exchange it is found that reverse osmosis desalination membranes can be applied to achieve surprisingly high ammonium removal from drinking water. It can be removed by different ways like ion exchange distillation reverse osmosis or boiling. Therefore for your application ammonia removal with ion exchange is probably not practical from a.
