Description
What is activated alumina?
Activated alumina is a non-hazardous form of aluminum oxide. It is designated “active” because it undergoes a specialized dehydration treatment that maximizes its surface area and adsorption capabilities.
With its exceptional porosity and proven safety profile, activated alumina has become a trusted solution for water treatment, air purification, and other critical applications where effective contaminant removal is essential.

Features & Characteristics of Activated Alumina
✔ Superior Adsorption Properties
Activated alumina’s porous structure enables exceptional adsorption capacity for moisture, gases, and other impurities.
✔ Selective Adsorption Performance
Activated alumina demonstrates remarkable precision in targeting specific molecules and substances to adsorb, enabling accurate separations and purifications.
✔ Regeneration Capability
Activated alumina can be regenerated through controlled heating to release captured moisture and impurities, providing long-term value and sustainability in industrial operations.
✔ Chemical Stability
Engineered to be chemically inert, activated alumina maintains its integrity when exposed to a broad spectrum of chemicals and gases, ensuring reliable performance across diverse applications.
✔ High-Temperature Resilience
With its excellent thermal stability, activated alumina performs well in high-temperature environments.
✔ Minimal Dusting
Activated alumina produces extremely low levels of dust, making it suitable for applications that require strict contamination control.
Applications of Activated Alumina
⦿ Desiccation
Activated alumina is a premium desiccant in industries manufacturing or using petrochemicals, gases, pharmaceuticals, and HVAC supplies. Its superior moisture removal capabilities protect valuable equipment and products from water-related degradation.
⦿ Water Treatment
As a highly effective adsorbent, activated alumina removes contaminants like fluoride, arsenic, and sulfates from water. It is used in both industrial and municipal water purification systems.
⦿ Other Process Stream Purifications
Offers reliable removal of organic compounds and other impurities from industrial process streams, ensuring product quality and process efficiency.
Benefits of Activated Alumina
⦾ Cost-Efficient
Because of its regenerative qualities, activated alumina can be reused multiple times while maintaining high performance. Compared to single-use alternatives, it is a wise choice in situations with sensitive operating budgets.
⦾ Environmental Stewardship
Activated alumina excels in removing harmful contaminants and moisture from gas streams, providing clean, dry air for various industrial processes and environmental control applications. Its powerful purification capabilities help industries maintain compliance with environmental regulations while contributing to cleaner air and water resources for their customers.
⦾ Quality Assurance
For industries where product purity is essential — petrochemistry and pharmaceutical, for example — activated alumina provides exceptional moisture and contamination control. These characteristics help companies meet strict quality standards and extend their product’s shelf life.
Guidelines for Handling and Storage of Activated Alumina
Activated alumina is safe, non-toxic, and can be handled using general hygiene guidelines. Refrain from smoking, eating, drinking, or raising dust during use. Wash your hands afterward.Â
Activated alumina should be stored in a dry, clean, airtight container.
