Activated alumina for fluoride removal
The product is a white, spherical porous material with the property of non-toxic, odorless, insoluble in water and ethanol.
The particle size is uniform, the surface is smooth, the mechanical strength is high, the ability of moisture absorption is strong and the ball is not split after absorbing water.
The partical size can be 1-3mm,2-4mm/3-5mm or even lower such as 0.5-1.0mm.With larger contact area with the water and specific surface area higher than 300m2/g, it has a big quantity of micropores and can ensure strong adsorption and high defluorination volume to fluorinnion in the water.
