The characteristics of activated alumina make it very useful in cleaning up toxic waste and stormwater runoff from polluted areas. Rainwater can absorb pollutants, such as soluble metals from industrial activities. It can also flush pollutants such as arsenic and lead from mining operations into groundwater. Activated alumina is not only great for cleaning up toxic spills, but it is also suitable for cleaning up toxic sites that have long been abandoned and are only now being targeted for clean-up. This shows that activated alumina is an effective way to clean up the environment and its ability to bind to toxic substances means that these substances do not leach back into the environment when they are treated.
Activated alumina is also an excellent desiccant, drying air and other gases with high humidity. It is thus used in the manufacture of hydrogen peroxide, and the dehydration and purification of natural gas and petrol.
In addition to this, it is used for water purification in industrial applications, municipal water treatment facilities, and domestic use. It excels in the removal of fluoride from drinking water as well as lead, arsenic, and other contaminants.
The high resistance to pressure, high porosity, and very stable chemical and physical properties of activated alumina make it one of the most important and useful elements in our high-tech society.
