Activated Alumina ball:
Applications:
Catalyst applications
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
Desiccant
Use as a desiccant, it works by a process called adsorption. The water in the air actually sticks to the alumina itself
in between the tiny passages, as the air passes through them. The water molecules become trapped so that the air
is dried out as it passes through the filter. This process is reversible, and if the alumina desiccant is heated to about 200°C it will release all of the water stored in it. This process is called regenerating the desiccant.
Fluoride adsorbent
used to remove fluoride from drinking water. In the US, there are widespread programs to fluoridate drinking water.
However, in certain regions, such as the Jaipur region of India, there is enough fluorine in the water to cause fluorosis.
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. Lower temperature water, and lower acidic water are filtered
more effectively too.
Vacuum systems
In high vacuum applications, it is used as a charge material in foreline traps to prevent oil generated by rotary vane
pumps from backstreaming into the system.
Biomaterial
Its mechanical properties and non-reactivity in the biological environment allow it to be a suitable material used to cover surfaces in friction in body protheses
(waist and shoulder protheses).
