In ammonia removal applications, zeolite can be regenerated using a brine solution, typically sodium chloride (NaCl). The process involves flushing the ammonia-laden zeolite with a concentrated salt solution, which replaces the ammonium ions (NH4+) adsorbed by the zeolite with sodium ions (Na+). This ion-exchange reaction restores the zeolite’s ability to adsorb more ammonium ions. After flushing with the salt solution, the zeolite is rinsed with water to remove any excess salts, making it ready for reuse in ammonia adsorption.
