Water softening systems - Lenntech
Water softening systems for hard water problems. Hardness in water is caused by certain salts. The main hardness causing ions are Calcium (Ca 2+), Magnesium (Mg 2+) and Bicarbonate (HCO 3-). These ions or minerals are normally addressed as scale in the water causing scaling of pipes and equipment in drinking water and process water systems.
Ion exchange - Wikipedia
Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange resin.More precisely, the term encompasses a large variety of processes where ions are exchanged between two electrolytes. Aside from its use to purify drinking water, the technique is widely applied for purification and separation of a variety of industrially and medicinally ...
Water Softening (Ion Exchange) — Publications
Cation exchange involves the replacement of the hardness ions with a nonhardness ion. Water softeners usually use sodium (Na+) as the exchange ion. Sodium ions are supplied from dissolved sodium chloride salt, also called brine. In the ion exchange process, sodium ions are used to coat an exchange medium in the softener.
Deionization is a physical process which uses specially manufactured ion exchange resins which provides ion exchange site for the replacement of the mineral salts in water with water forming H+ and OH- ions. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to ...

ness minerals. This NebGuide focuses on the ion exchange softening process which remains the most commonly used technique for managing hard water in residential settings. Contaminants removed by the water softening (ion . exchange) process. The ion exchange water softening process can remove nearly all calcium and magnesium from source water.
Water Handbook - Ion Exchange & Water Demineralization | SUEZ
Ion exchange dealkalization systems produce hardness-free, low-alkalinity water at a reasonable cost, and with a high degree of reliability. They are well suited for processing feedwater for medium-pressure boilers, and for process water for the beverage industry. Split stream and weak acid cation systems also reduce the total dissolved solids.

What Is Ion Exchange? - Fluence Corporation
Jan 27, 2016· 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.
Water quality information - Water Deionization Process ...
Among all common water filtration methods, the process used for removal of all dissolved salts from water is referred to as deionization. Deionization requires the flow of water through two ion exchange materials in order to affect the removal of all salt content.
What is an Ion Exchange System and How Does it Work?
Jun 05, 2017· 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.
Iodine Production & Extraction Process | Iodeal Brands

Ion Exchange Water Softening - SAHRA
In the ion exchange process, a granular substance (usually a resin) that is coated with sodium or potassium ions comes into contact with water containing calcium and magnesium ions. Two positively charged sodium or potassium ions are exchanged (released into the water) for every calcium or magnesium ion that is held by the resin.

ION EXCHANGE - Thermopedia
The kinetics of ion exchange are governed by either a diffusion or mass action mechanism, depending on which is the slowest step. Diffusion of ions in the external solution is termed liquid film control, but is hydrodynamically ill-defined.The diffusion and transport of ions within the ion exchanger is termed particle diffusion control.Chemical reaction (step 3) is uncommon but can be rate ...
WHEY PROCESSING | Dairy Processing Handbook
Ion exchange processes for demineralization. Demineralization by ion exchange has long been an established process for water treatment but has also been adopted for 'de-ashing' of whey. Whey is not a uniform product as to composition. Whey from an acid casein/cheese curd has a pH of 5.9 – 64.3, while the pH of sweet whey is 6.3 – 6.6.
