For example, activated alumina is widely used in air separation & drying applications, as these adsorbents are appropriate for use in dehydrating gases in both thermally regenerative and pressure swing modes.
The commonly used desiccants and adsorbents are silica gel, activated alumina, activated carbon, molecular sieves, Montmorillonite clay, and alumino-silicate minerals (ceramic balls) or reactive ∝-alumina (tabular alumina).
The method uses nano-cavitation and activated alumina with the capacity of 40 liters per second.

Reverse-osmosis filters and carbon filters with activated alumina remove most of the fluoride, but water softeners and charcoal or carbon filters do not.
Using activated alumina technology, both community and domestic defluoridation can be carried out.
