Al2O3 active alumina is a mineral adsorbent with high porosity and high strength. It is a material produced by thermal treatment of alumina Al2O3. Thanks to its unique properties, it is widely used in industry for drying gases and liquids, as well as for the removal of other trace impurities. Commercial names of activated alumina include: BASF F-200, AxSorb, SORBEO
Active alumina is a material with high mechanical strength and chemical resistance. It does not swell and is not damaged in contact with liquid water, which allows it to be used in situations where water may condense from the flowing gas. It is a thermally stable material, and its specific internal structure allows the adsorption of various trace impurities. Thanks to its excellent resistance to abrasion and crushing, relatively easy regeneration combined with the possibility of drying to a pressure dew point of at least -40°C, it is widely used in compressed air drying applications.
Active alumina is also a material for use in water and wastewater treatment processes. Active alumina filters are used to remove fluoride, phosphate, arsenic and heavy metals. In particular, it has unique fluoride adsorption properties, both in water treatment and wastewater. Active alumina filters can be operated with and without regeneration.
