Project at a Glance	Contents on the CD ROM
Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material. Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, in sulfur removal from gas streams (Claus Catalyst process). Activated alumina is also widely used to remove fluoride from drinking water. In the US, there are widespread programs to fluoridate drinking water. Activated alumina filters can easily reduce fluoride levels from .5 ppm to less than .1 ppm. The amount of fluoride leached from the water being filtered depends on how long the water is actually touching the alumina filter media. Basically, the more alumina in the filter, the less fluoride will be in the final, filtered water. Defluoridation using Activated Alumina (AA) has been one of the widely used adsorption/ ion exchange methods water and many reports are available on large-scale installations for townships, requiring supervision and skilled personnel. The quality of treated water from such facilities was assured. Regeneration of exhausted Activated Alumina and its reuse for multiple cycles is one of the main advantages of using Activated Alumina for defluoridation. Activated alumina treatment is used to attract and remove contaminant, like arsenic and fluoride, which have negatively charged ions. Activated alumina (a form of aluminum oxide) is typically housed in canisters through which source water is passed for treatment. A series of such canisters can be linked together to match the water volume requirements of any particular system. Activated alumina technology can be expensive, and many of its costs are associated with disposal of the contaminated water that is created when alumina is purged of contaminants and “reset” for future use. Large-scale activated alumina systems also require a high level of operational and maintenance expertise, and consequently are relatively rare. Activated Alumina is a highly porous form of aluminum oxide, produced by partially dehydrating Aluminum Trihydrate. Activated Alumina has the ability to adsorb a large number of contaminants as a result of its highly porous structure. This porosity and the surface chemistry of Activated Alumina gives it catalytic properties useful in many industrial applications.
