Alumina Defluorination Agent is akind of white, spherical and porousgranule with epigranular, smooth surface, high mechanical strength andstrong hygroscopicity, non-swelling and non-cracking and staying the sameafter absorbing water. non-toxic,odorless, insoluble in waterandorganic solvent.

This product can be used as the fluorine-removal agent for high fluorine water, It is a kindof molecular absorbent with large specific surface area. Its defluorination capacity(it can be more than 3.0mg/g) is higher as the PH value of raw water and alkali value are lower,bt its price is lower than syntheticresin. It can also be used as the arsenic removal for drinking water. its particle size is generally 1-3mm,It has large area of contact with water when use, its surface area can be more than 30m2/g, its largeamount of micropore can guarantee the strong absorbent ability of fluorinion in water.
