Optimized for the efficient adsorption of hexavalent chromium (a toxic pollutant, from wastewater or drinking water)
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.
