Ion Exchange Water Treatment

Boiler cooling water and fireside treatment chemicals we also offer.

Ion exchange water treatment.

When it comes to water softeners magnesium and calcium ions are replaced by sodium ions. Rohm and haas ion exchange ion exchange introduction 1 fd sep 2008 ion exchange for dummies an introduction water water is a liquid. Ion exchange is a water treatment method where one or more undesirable ionic contaminants are removed from water by exchange with another non objectionable or less objectionable ionic substance. Polymers and polyelectrolyte s for water and non water processes.

At ion exchange we bring you total environment solutions water treatment waste water treatment recycle zero liquid discharge. Meeting today s needs innovating for the future. Water is made of water molecules formula h2o. But what exactly is it.

All natural waters contain some foreign substances usually in small amounts. Both the contaminant and the exchanged substance must be dissolved and have the same type of electrical charge positive or negative. Ion exchange is widely used in the food and beverage industry hydrometallurgy metals finishing chemical petrochemical pharmaceutical technology sugar and sweetener production ground and potable water treatment nuclear softening industrial water treatment semiconductor power and many other industries. The terms ion exchange deionization and demineralization are often used synonymously to refer to the same process.

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. Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge. However deionization and demineralization may be accomplished by technologies other than ion exchange see reverse osmosis ion exchange is a process used extensively in nuclear facilities industrial processes and medical and pharmaceutical operations to control the. This chemical process occurs because ions have differing affinities for the resin and these ions will replace ions with less attraction as they flow over the media.

In an ion exchange system undesirable ions in the water supply are replaced with more acceptable ions. Ion exchange systems are used for efficient removal of dissolved ions from water. Specialists in water and environment management for over five decades we provide solutions across industry homes and communities integrating extensive process technologies design engineering and project. These systems work by exchanging specific ions for other ions.

Ion exchangers exchange one ion for another hold it temporarily and then release it to a regenerant solution.
