Activated Alumina is a porous, high-surface-area form of aluminum oxide engineered for efficient adsorption of moisture, acids, and polar contaminants from gases and liquids. Designed for consistent performance in flow-through systems, it delivers reliable purification while maintaining low pressure drop and minimal dusting—making it well-suited for solvent processing and filtration setups.

This media is thermally activated to create a uniform network of micro- and mesopores, enabling strong affinity for water and other polar compounds. Its robust structure resists attrition, allowing for repeated use and dependable operation in both small-scale and industrial applications.

Key Features

* High Surface Area: Typically 250–350 m²/g for strong adsorption performance
* Effective Moisture Removal: Adsorbs up to ~20% of its weight in water, depending on conditions
* Low Dust / High Strength: Spherical beads minimize fines and maintain integrity under flow
* Uniform Particle Size: Promotes even distribution and reduces channeling in columns
* Thermally Regenerable: Can be reactivated through controlled heating for extended service life
* Chemical Stability: Performs across a wide pH range and in various solvent environments

Applications

* Solvent drying and polishing (hydrocarbons and alcohols)
* Inline and column-based filtration systems
* Color remediation support media in multi-layer stacks
* Compressed air and gas dehydration
* Removal of acids, peroxides, and trace impurities
