What is resin flushing?
By flushing the resin, the contaminant ions are released into a waste stream, and the cations and anions in the resin are restored for another cycle. Resins are designed to resist thermal degradation and oxidizing agents, as well as organic fouling.
What happens when water flows through resin beads?
In general, water containing undesirable ions flows through a bed of resin beads and the problematic ions are exchanged for ions of similar charge that were first applied to the resin. The functional groups and initial counterions are designed such that the ions in the treated water will have a greater affinity for the charged functional groups and will dislodge the existing ions and take their place, bonding with the functional groups through shared electrostatic attraction [ 2 ].

What is ion exchange resin?
This type of resin is otherwise known as a cation style resin. It hosts the swapping of positive and negative ions on its surface.
What is a weak base anion?
Weak base anion (WBA) resins actually are acid absorbers as#N#much as they are ion exchange resins. They remove only the anions of the strong#N#mineral acids (sulfate, chloride and nitrate). They allow the#N#carbonate/bicarbonate and silica ions to pass through. Therefore, they cannot#N#be used to make demineralized water without a SBA resin bed following in the#N#train to remove the carbonate/bicarbonate and silica. The advantage of using#N#the WBA resin is its efficiency. It is fully regenerated using only about 120#N#percent of stoichiometry. Like their WAC counterparts, WBA resins can be#N#regenerated using the spent caustic from the SBA resin bed making their use#N#very efficient especially when used on water having a high percentage of anion#N#loading from sulfate, chloride or nitrate.
What is weak acid cation resin?
Weak acid cation (WAC) resins can be used in#N#demineralization and dealkalization systems. They are very efficient when#N#matched up with the proper influent water chemistry. In the study referenced#N#previously, only 2.6 percent of the samples submitted for analysis were WAC#N#resins and of these, 63 percent of them came from locations outside of the#N#United States. With many water supplies in the United States being high in#N#hardness and alkalinity, these figures may indicate that system designers in#N#the United States largely ignore the use of WAC resins. Designers of industrial#N#water treatment systems may want to look at WAC resins more often in an effort#N#to improve system performance and decrease operating costs.
What is SAC resin used for?
Strong acid cation (SAC) resins probably are the most common#N#resins in use today. They are used in softening and demineralization#N#applications. In softening applications, the resin is used in the sodium form#N#(regenerated with salt) and in demineralization applications the resin is used#N#in the hydrogen form (regenerated with acid). SAC resins also can be used in a#N#split-stream dealkalization process. SAC resins can be purchased with different#N#percentages of crosslinkage. The common SAC resin is 8 percent crosslinked.#N#However, SAC resins are available in both higher and lower levels of#N#crosslinkage. Often a 10 percent crosslinked resin will be used in applications#N#where the influent water has a higher level of chlorine or an elevated water#N#temperature. Chlorine as well as oxygen at elevated temperatures will attack a#N#resin's crosslinkage. Having the higher initial level of crosslinkage often#N#will provide for a longer useful resin life. SAC resins with less than 8#N#percent crosslinkage may be used in electric utility condensate polishing#N#applications where they are reported to do an excellent job of removing#N#corrosion products (crud) from the utility's condensate.

What are some examples of nontreatment options?
Examples include interconnection with another system and drilling a new well to replace a contaminated one.
What is channeling in a resin?
Channeling is a condition in which the resin allows a direct flow of water through theion exchanger. Flow channels are established from the inlet to the outlet of the ionexchanger, which allows water to flow essentially unrestricted through the resin viathese paths. If channeling occurs, the water flowing through the resin bed hasinsufficient contact with the resin beads and results in a decrease in effectiveness of theion exchanger.
Why is raw water used as makeup water?
Because of the presence of impurities, raw water sources undergo treatment priorto use as makeup water in reactor facility systems. These systems normally utilizeseveral distinct processes that remove solids, ionic impurities, and gases.Pretreatment of makeup water is necessary to reduce corrosion, minimizeradiation, and limit fouling of heat transfer surfaces.
How does ion exchange work?
Ion exchange is a process used extensively in nuclear facilities to control the purity and pH ofwater by removing undesirable ions and replacing them with acceptable ones. Specifically, it isthe exchange of ions between a solid substance (called a resin) and an aqueous solution (reactorcoolant or makeup water). Depending on the identity of the ions that a resin releases to thewater, the process may result in purification of water or in control of the concentration of aparticular ion in a solution. An ion exchange is the reversible exchange of ions between a liquidand a solid. This process is generally used to remove undesirable ions from a liquid andsubstitute acceptable ions from the solid (resin).
What is the process of demineralizing water?

How does the IX resin work?
The IX resin functions this way because of its functional groups, which are essentially fixed ions that are permanently bound within the polymer matrix of the resin. These charged ions will readily bond with ions of an opposing charge, which are delivered through the application of a counterion solution.
What happens to resin after it is exhausted?
Once the resin is exhausted, it must be restored for further use through what is known as a regeneration cycle. During a regeneration cycle, the IX reaction is essentially reversed through the application of a concentrated regenerant solution.
What is ion exchange resin?
What are ion exchange resins? Ion exchange is a reversible chemical reaction where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charge. Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions.
What happens to the functional groups of the IX resin?
As the solution moves through the IX resin, the functional groups of the resin attract any counterions present in the solution.
