What is an Ion Exchange System and How Does it Work?

 · Ion exchange (IX) systems are used across a variety of industries for water softening, purification, and separation purposes. While the chemistry of individual ion exchange reactions varies from one application to the next, IX is a treatment process where dissolved ions are replaced by other, more desirable, ions of a similar electrical charge.

Applications of Ion Exchange

Ion exchange is a technique for producing soft water in filters, which is beneficial to laundry detergents, soaps, and water heaters. Exchanging divalent cations (e.g., calcium Ca2+ and magnesium Mg2+) with highly soluble monovalent cations (e.g., Na+ or H+) does this (see water softening). The removal of nitrate and natural organic ...

Ion exchange resins and polymeric adsorbents, as produced, contain by-products resulting from the manufacturing process. The user must determine the extent to which organic by-products must be removed for any particular use and establish techniques to assure that the appropriate level of purity is achieved for that use.

ION EXCHANGE

The ion exchange process is widely used for the removal of hardness (as in softening), heavy metals (as in waste treatment), radionuclides (as from power plants) and municipal water feeds (removal of nitrates, arsenic, perchlorate, hexavalent-chrome and others).

Ion Exchange Water Treatment Systems

How does ion exchange water treatment work? Ion exchange water treatment works by removing material from the water through the use of water processes such as water softening, and water deionization. These systems work by exchanging specific ions for other ions. When it comes to water softeners, magnesium and calcium ions are replaced by sodium ...

Ion exchange

Definition of Ion Exchange Ion exchange is the process through which ions in solution are transferred to a solid matrix which, in turn releases ions of a different type but of the same polarity. In other words the ions in solutions are replaced by different ions originally present in the solid. PIERO M.

Ion-Exchange Chromatography

Ion-Exchange Chromatography. A second sub-category of liquid chromatography is known as ion-exchange chromatography. This technique is used to analyze ionic substances. It is often used for inorganic anions (e.g., chloride, nitrate, and sulfate) and inorganic cations (e.g., lithium, sodium, and potassium). It can also be used for organic ions ...

Ion-exchange membrane

An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules.. Ion-exchange membranes are therefore electrically conductive. They are often used in desalination and chemical recovery applications, moving ions from one solution to another with little passage of water.
