Activated ball for water purification can insure high fluorine-removed capacity for the fluorinion in water.
Detailed introduction to Activated Alumina Ball For Water Purification:
Activated balls for water purification is a white, spherical porous material with the property of non-toxic, tasteless, odorless, insoluble in the water and organic solvents. The particle size is uniform, the surface is smooth, the mechanical is strong , the ability of moisture absorption is strong and the ball is not split after absorbing water.
The product is a molecular adsorbent with large specific surface area when it is used as defluoridizer for high-fluorine water. It has a high capacity of algal fluorine when the PH value and alkalinity of raw water is low, it is more than 3.0mg/g and the price is lower than synthetic resin. Besides that it also can be used for remove the arsenic in drinking water.
A smaller particle size allows a larger surface area of this product, generally speaking, it is 1-3mm.It has a larger contact area in water and the surface area can be up to 260 m / g ,the quantity of porous is huge ,so it can insure the strong adsorption capacity and high fluorine -removed capacity for the fluorinion in water.
