Ion exchange sand filters are the most common type of filter used in commercial water treatment. The sand is saturated with resin, which attracts and binds with ions. The resin that's present in the sand is called synthetic zeolite, and it has a number of advantages over natural zeolites. These include its ability to bind larger amounts of contaminants than natural zeolites, which allows for better filtering performance at lower cost (since you don't have to use as much material).
