Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 m²/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al2O3). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has. Activated alumina in its phase composition can be represented only by metastable forms (gamma-Al2O3 etc.).
Application:
This prodcut is a white spherical garanule with high fluoride removal capacity,high strenth ,non-breaking in water immersion,safe and reliable use.The purified water quality of the product can meet the national drinking water hygiene standards,the effect of fluoride removal is remarkable.The static capacity of fluoride removal is more than 3mg/g-AL2O3.This product can also be used for fluoride removal in other petrochemical process.
