Activated Alumina
Activated Alumina Overview

Adsorbent for Drying, Purification, and Water Treatment
Activated alumina is a highly porous, aluminum oxide–based adsorbent widely used for drying, purification, and contaminant removal in industrial gas, air, and water treatment applications.
Due to its high surface area and mechanical strength, activated alumina provides reliable adsorption performance under demanding operating conditions. Therefore, it is commonly applied where moderate drying capacity, chemical stability, and long service life are required.
What Is Activated Alumina?
Activated alumina is a porous form of aluminum oxide (Al₂O₃) produced through controlled dehydration of aluminum hydroxide. The resulting material has a large internal surface area, enabling it to adsorb moisture and various contaminants from gases and liquids.
In Contrast to molecular sieves, activated alumina offers broader adsorption behavior, making it suitable for applications where ultra-deep dehydration is not required but robust, cost-effective drying or purification is essential.
Key Applications

Air and gas drying
Removal of moisture from compressed air, process gases, and industrial gas streams.

Water treatment
Adsorption of fluoride, arsenic, selenium, and other trace contaminants in potable and process water.

Gas purification
Removal of acidic or polar impurities prior to downstream processing.
