Activated alumina is a porous, highly dispersed material with large surface area, microporous surface with catalytic performance, strong adsorption performance, and good thermal stability, so it is widely used as ideal material for the manufacturing of desiccant, adsorbent, catalyst, gas or water purificant.
As the most common industrial desiccant, adsorbent, activated alumina products are widely used in air separation and preparation, PSA pressure swing adsorption, gas drying, desulfurization, dechlorination and defluorination, hydrogen peroxide production, water treatment, catalyst preparation for petroleum, petrochemical and fine chemical industry.
As a Fluoride remover for high fluorine water, it is a molecular adsorbent with a large specific surface area. When the PH value and alkalinity of the raw water are low, the fluoride removal capacity is higher than 4.0mg/g, and it can also be used for arsenic removal in drinking water.
The normal size is 1-3mm, 2-4mm. It has a large contact area with water, the surface area come up to 320㎡/g, and the number of micropores is large, which can ensure a strong adsorption capacity for fluoride ions in water. and higher fluoride removal capacity.
