A Brief History of Ion Exchange Water Treatment - WCP Online

From 1913 to 1938, water softening accounted for most water conditioning and it was not until 1936 that dissolved solids reduction was achieved using ion exchange. It is from these beginnings that our industry developed in this country and today, millions of cubic feet of a variety of ion exchange media are produced for water treatment purposes.

What Is Ion Exchange? - Fluence Corporation

Ion exchange is a water treatment process commonly used for water softening or demineralization, but it also is used to remove other substances from the water in processes such as dealkalization, deionization, and disinfection.. But what exactly is it? Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge.

Ion Exchange Resin | History & Development - Water

History of Ion Exchange Resin: Two Englishmen Thompson and Way, first recognized the process of ion exchange in 1850. They reported that when a fertilizer solution poured over a column of soil, ammonia in the fertilizer solution was replaced by calcium from the soil. Ion exchange was not used for any industrial application until 1905.

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.
