Activated alumina is prepared from high-purity alumina through controlled calcination and activation processes, resulting in a high specific surface area and a uniform porous structure. This structure enables it to exhibit excellent efficiency and stability in adsorbing moisture, fluoride ions, and various polar impurities.
In industrial applications, activated alumina adsorbents are often used to lower the dew point of gases, remove trace moisture, and improve the purity of media. They are particularly suitable for continuous process systems that require high operational stability.
Typical Applications of Activated Alumina as an Industrial Desiccant
As a mature industrial desiccant, activated alumina is widely used in compressed air drying, natural gas dehydration, and refrigerant drying. In fixed-bed or adsorption tower systems, its high mechanical strength effectively reduces pulverization and pressure drop, helping to extend equipment lifespan.
Compared to some disposable desiccant materials, activated alumina possesses excellent regenerability and can be regenerated and reused multiple times under appropriate conditions, thereby reducing overall operating costs.
Applications of Activated Alumina in Water Treatment and Environmental Protection
In drinking water and industrial wastewater treatment, activated alumina is widely used in defluoridation processes due to its selective adsorption capacity for fluoride ions. By rationally designing the contact time and bed height, stable and controllable treatment results can be achieved while ensuring water quality meets standards.
With continuously improving environmental standards, the demand for activated alumina in water treatment and environmental protection is showing a sustained growth trend.
