Wholesale D290 Macroporous Strong-Base Anion Exchange Resin Manufacturer and Supplier

D290 Macroporous Strong-Base Anion Exchange Resin

For Efficient Demineralibation Including vanadium Removal

D290 is a high capacity, shock resistant, macroporous,Type I ,strongly basic anion exchange resin supplied in the chloride or hydroxide form as moist, tough, uniform, spherical beads.

D290 has a high operating capacity, especially on high-FMA feedwaters, as well as a high reversible sorptive capacity for complex organic materials, such as the fulvic and humic acids which occur in many surface water supplies.

It is recommended for use in waters with low silica loads. For high silica waters, a type 1 anion resin such as Pure D290 is recommended.
