    Exhausted zeolite can be regenerated through several methods, depending on the contaminants it has adsorbed. For typical gases like nitrogen, regeneration is performed by reducing pressure (Pressure Swing Adsorption, or PSA) or applying heat (Thermal Swing Adsorption, or TSA). For zeolites used in water treatment or ammonia removal, chemical regeneration may be used by rinsing the zeolite with a salt solution (e.g., sodium chloride). The choice of method depends on the type of zeolite and the nature of the contaminants. Combining purging, pressure, and heat can effectively restore zeolite’s adsorption capacity.
