How does zeolite regeneration ammonia removal occur?

    Zeolite regeneration for ammonia (NH4⁺) removal occurs through a chemical ion-exchange process:

    Backwashing: First, backwash the zeolite bed with clean water to remove physical debris or particulates.
    Brine Solution: Flush the zeolite with a concentrated sodium chloride (NaCl) brine solution, typically 5%-10%. The sodium ions from the solution displace the ammonium ions (NH4⁺) adsorbed on the zeolite.
    Rinse: After the brine treatment, rinse the zeolite with fresh water to remove excess salt and displaced ammonium ions.
    Recharging: The zeolite is now ready to continue adsorbing ammonium ions from the water, having restored its ion-exchange capacity.
    This regeneration cycle can be repeated multiple times, ensuring the zeolite continues to function in ammonia removal applications.
