Ion Exchange

For more info, call 1-800-241-3224
Ion exchange is a reversible chemical reaction in which a dissolved ion displaces a fixed ion from a functional site on an insoluble, stable molecule. Only dissolved species (ions) participate in ion exchange. Other contaminants may be filtered from the water, or may chemical absorb on the ion. The exchange is reversible; the exchange direction is determined by the concentration of ions in the immediate environment of the exchange site.

Ion exchange technology is utilized in different applications, depending on the influent water quality and effluent water needed.

Crossbow Water offers a large selection of ion exchange technology to meet customer’s needs. To learn more about a specific product, click on a link below. (PDF brochure - will open in new window)

Water Softening is the use of ion exchange to remove calcium and magnesium from hard water. Crossbow Water offers a complete range of water softener systems to meet your need for softened water. Electrodeionization (EDI) utilizes ion exchange resins and electricity to produce ultra pure deionized water. EDI is a continuous and chemical-free process of removing ionized and ionizable species from water using DC power. Crossbow Water can work with you to design an EDI system to meet your needs. Deionization is a physical process, which uses specially manufactured ion exchange resins that bind to and filter out the mineral salts from water. Deionization produces a high purity water that is generally similar to distilled water. Crossbow Water provides deionization solutions ranging from under-the-sink tanks to trailers.
