Water Purification Filler Activated Alumina Sphere Granule

Activated alumina has an adsorption effect on arsenic in water. Accumulation of arsenic on activated alumina causes a decrease in the adsorption capacity of fluoride ions, and makes elution of arsenic ions difficult during regeneration.

Activated alumina ball defluorination agents generally use 1-3mm smaller particle diameter products. The smaller the particle size, the stronger the defluorination ability.

When the pH value and alkalinity of raw water are low, the fluoride removal capacity is high, greater than 3.0mg / g, and it can also be used to remove arsenic from drinking water. The smaller particle size can make the product have a larger external surface area, generally 1-3mm, and has a large contact area with water during use. The specific surface area index is as high as 160m2 / g or more, and the number of micropores is huge, which can ensure a strong adsorption capacity for fluoride ions in water and a high capacity for removing fluoride and arsenic.
