Activated Alumina

Activated Carbon Depot offers premium Activated Alumina for water treatment, air and gas drying, industrial processing, and environmental filtration applications. Manufactured with a highly porous aluminum oxide structure, activated alumina provides exceptional adsorption capacity for moisture and select dissolved contaminants, making it one of the most versatile specialty filtration media available.

Activated alumina is widely used to remove fluoride, arsenic, selenium, and other impurities from water while also serving as an effective desiccant for drying compressed air, natural gas, and industrial process streams. Its high surface area, mechanical strength, and long service life make it a trusted solution across municipal, commercial, and industrial applications.

What Is Activated Alumina?

Activated alumina is a granular, highly porous form of aluminum oxide (Al₂O₃) that adsorbs contaminants and moisture through its extensive internal surface area. Unlike activated carbon, which primarily removes organic compounds, activated alumina is specifically designed to target inorganic contaminants and water vapor.

Its unique adsorption properties make it an effective media for applications requiring:

• Fluoride reduction
• Arsenic removal
• Selenium removal
• Moisture adsorption
• Air drying
• Gas dehydration
• Industrial purification
• Process water treatment

Activated alumina is frequently incorporated into multi-stage treatment systems alongside activated carbon and other specialty media for comprehensive contaminant removal.

Water Treatment Applications

Activated alumina is widely used in water treatment systems where specific inorganic contaminants must be reduced to improve water quality.

Common applications include:

• Drinking water treatment
• Municipal water systems
• Well water treatment
• Point-of-entry filtration systems
• Point-of-use filtration systems
• Industrial process water
• Laboratory water purification
• Groundwater remediation
• Environmental treatment systems
• Commercial water filtration

When properly selected and maintained, activated alumina provides effective contaminant reduction while supporting consistent water quality.

Air & Gas Drying Applications

In addition to water treatment, activated alumina is one of the industry's most widely used desiccant materials for removing moisture from compressed gases and air systems.

Typical applications include:

• Compressed air dryers
• Instrument air systems
• Natural gas dehydration
• Refrigeration systems
• Chemical processing
• Petrochemical facilities
• Oxygen generation systems
• Industrial gas purification
• Manufacturing operations
• Air separation equipment

Its high moisture adsorption capacity helps protect equipment from corrosion, freezing, and reduced operating efficiency.
