Activated Alumina


Activated Alumina Desiccant

Activated alumina Is a high-surface-area, highly porous form of aluminum oxide. It can adsorb gases and liquids without changing its form. It works as a desiccant through adsorption. As air enters into the pores of the alumina, the water in the air becomes trapped and the air that continues to pass through an activated alumina filter is dried out.  Even if immersed in a liquid, Activate Alumina will not fall apart or soften.

You can restore the original adsorption efficiency of activated alumina by heating it to any temperature from 350° to 600°F (177° to 316°C). When the desiccant is heated as described above, the water stored in it is released. This means that filters with AA can be reused over and over again.

Air and Gas Drying: BASF F-200 can dry almost all liquids and gases. To achieve efficient storage, transportation, and processing of fluid, it's often necessary to remove water.
