WebEffective ion exchange for challenging water-treatment needs. Ion exchange (IX) is the reversible interchange of ions between a solid and a liquid such as water. Ion exchange resins remove harmful contaminants from liquids, replacing them with beneficial, desired ions. Ion exchange is used in water treatment, including water softening ... WebAug 23, 2024 · Ion exchange replaces (or exchanges) unwanted minerals in water with less objectionable ones. Chloride and hydroxide ions are the most commonly used materials on the resin beads. As water passes through the device, the resin adsorbs anions such as sulfate, nitrate, arsenic and bicarbonates and releases chloride into the water.
WebJun 5, 2024 · After being placed in a solution and dissolved, the ion atoms separate into two groups: a positive “cation” or a negative “anion”. This solution is then passed through a resin, causing ions in the solution to be exchanged with equally-charged contaminants in the water on the other side of the resin. A Cation is an atom with a positive ... WebFeb 27, 2024 · The ion exchange process is a popular drinking water treatment method.
