Zeolite is primarily found in which type of system?

Zeolite is primarily used in water softening systems due to its unique ion-exchange properties. It works by exchanging sodium ions for hardness ions like calcium and magnesium present in water, effectively reducing water hardness. This process is crucial in preventing scale buildup in pipes and appliances, extending their lifespan and improving efficiency. Zeolite's ability to selectively filter out these ions makes it an ideal choice for water treatment applications, specifically in softening processes. In contrast, cooling systems, heating systems, and pressure relief systems do not utilize zeolite for their operational purposes, which primarily focus on thermal regulation and pressure management rather than water quality.
