White, spherical, porous granules with uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, and do not swell or crack after absorbing water, maintaining their original shape. The product is odorless, tasteless, and insoluble in water and organic solvents.

This product is used as a defluorination agent for high-fluoride water, featuring a high surface area molecular adsorbent. When the pH and alkalinity of the raw water are low, its defluorination capacity is high, exceeding 4.0 mg/g, and it can also be used for arsenic removal in drinking water.

Particle sizes are typically 1-3mm, 2-4mm, and 3-5mm, offering a large contact area with water during use. The specific surface area is over 280㎡/g, with an immense number of micropores, ensuring strong adsorption capability and high fluoride removal capacity for water.
