Abstract
Methods and apparatuses are provided for the removal and destruction of ammonia from an aqueous medium. The methods and apparatuses include the removal of ammonia from an aqueous medium by contact with either natural or synthetic zeolite. The spent zeolite is re-generated for continuous use, while the ammonia is concentrated as ammonium sulfate, and ultimately destroyed via combustion. A system for monitoring and maintaining an ammonia removal system by an off-site provider is also disclosed.
