Ion exchange (IX) technology is a process used to remove or exchange ions in a solution, primarily for water purification and softening. This concept emerged in the early 20th century, with significant advancements in the 1940s and 1950s when synthetic resins developed for more efficient ion exchange.
In this process, ions in a solution are exchanged with ions from a resin with a strong affinity for specific ions. For example, calcium and magnesium ions are replaced with sodium ions in water softening. Ion exchange is widely employed in water treatment, wastewater management, and various pharmaceuticals and food processing industries.
Advancements in resin technology and process optimization have improved the efficiency of ion exchange systems, making them essential for ensuring water quality and meeting regulatory standards across different sectors.
Persalt has developed a state-of-the-art product line for ion exchange (IX), adsorbent, chelating, and catalyst resins. PersaLite™, PersaPore™, PersaChel™, and PersaLyze™ gel and macroporous resins are manufactured to the highest quality standards, ensuring optimal performance and durability.
We supply uniform particle-size ion exchange resins certified for treating a variety of liquid streams. These resins extend the service life of the beds, require fewer chemicals for the regeneration process, and reduce operational costs for demineralization and drinking water treatment plants. Our IX resins offer high ion exchange capacity and excellent mechanical strength.
Our competitive edge is in offering IX resins that match the quality of traditional manufacturers while delivering the best cost-benefit ratio in the industry.
PersaLite™ IX Resin Series: This series comprises organic polymers that attract oppositely charged ions, facilitating the ion exchange. The cation exchange resin displaces cations, while the anion exchange resin displaces anions. Combined, they form a mixed bed ion exchange resin, allowing for the simultaneous exchange of positive and negative ions, essential for purifying feed water streams.
PersaPore™ Adsorbent Resin Series: This series features macroporous adsorbent polymers designed to utilize adsorption principles to separate organic particles. A notable application is removing organic molecules from juices and sugars, enhancing their quality and taste.
PersaChel™ Chelating Resin Series: These are specialized ion exchange resins engineered with various functional groups to improve selectivity for specific metals. They effectively remove boron from potable water and can recover valuable metals such as gold and palladium.
PersaLyze™ Catalyst Resin Series: Comprises gel or macroporous styrene-based sulfonic resins. Catalyst resins serve multiple catalytic processes, including acrylic ester production and isobutylene etherification, contributing to various chemical transformations.
