ABSTRACT:
An ammonium removal system includes an ion-exchange medium, a brine source, and an electrophysical separation system. The ion-exchange medium may be used to remove ammonium from a waste stream. A brine may be flushed through the ion-exchange medium to remove the ammonium from the ion-exchange medium. The ammonium containing brine may be treated using an electrophysical separation system.
