Resin Traps: Protecting Ion Exchange Systems from Media Loss

Ion exchange systems are widely used in water treatment, power generation, chemical processing, and ultrapure water production. Their performance depends heavily on the integrity of the ion exchange resin. When resin escapes from a vessel, it can reduce treatment efficiency, damage downstream equipment, and increase operating costs.
