Chromium Resin

A premium-grade strong anion exchange resin designed for the removal of hexavalent chromium (Cr(VI)) and uranium from water. It operates by exchanging negatively charged anions, such as Cr(VI), for chloride ions in the resin matrix.

The resin features quaternary amine functional groups, offering high capacity and exceptional physical stability for long-term use. Pretreatment, including prefiltration, is recommended to protect the resin bed from fouling. Suitable for various water treatment applications and does not typically require pH adjustment during operation. It ensures reliable performance and extended operational life.

The Strongest Shield Against Toxic Chromium

Strong Base Anion (SBA) Exchange is an ion exchange process where negatively charged anions in water are transferred to a solid resin phase, displacing chloride or other ions from the resin matrix. This method is widely used in drinking water treatment to remove contaminants like nitrate, arsenic, and other groundwater pollutants, supported by extensive research.

In hexavalent chromium (Cr(VI)) removal, raw water undergoes pretreatment—typically prefiltration—to prevent particulate fouling of the resin bed. Unlike some treatment processes, SBA resins remain ionized across a broad pH range, eliminating the need for pH adjustment in most cases. The pretreated water then flows through pressure vessels containing SBA resin, where Cr(VI) and other anions are exchanged for chloride ions.

A high-performance gel-type I strong anion exchange resin in chloride form, featuring quaternary amine (trimethylamine) functional groups and an exceptionally high capacity. Specifically engineered for Cr(VI) and uranium removal, it combines superior operating capacity with robust physical stability, ensuring long service life in demanding applications.
