Activated Alumina and its Benefits

Activated Alumina is a very commonly used desiccant. It is generally manufactured by dehydroxylating Aluminium Hydroxide in such a manner that the end result is a highly porous material. It is this porous material, which is widely used in removing impurities from the surroundings. Activated Alumina is known to have a surface area of more than 200 square metres/g. This desiccant is not only widely used for its large surface area but also for its very high surface-area-to-weight ratio, which make the adsorbent process faster and more effective.

 

The main benefits of using Activated Alumina is that more moisture molecules/impurities can be absorbed over more area in a shorter period of time. The numerous tunnel-like pores of the Activated Alumina desiccant are its biggest plus-point. They allow only those molecules to pass through, which are smaller than the even-sized pores while the larger molecules are left behind. This is how Activated Alumina desiccant successfully filters substances.

 

Activated Alumina for Effective Water Filtration

 

Activated Alumina Water Filter

Activated Alumina balls are the first choice of municipal corporations around the world for removing impurities like fluoride, arsenic and selenium from water meant for drinking and household purposes. This is done by immersing Activated Alumina filters into the water, which is to be removed of impurities. When it comes in contact with the water, the Activated Alumina desiccant will begin its work and start absorbing all the impurities present in the water. Main among these impurities is fluoride, which can lead to many complications like fluorosis, weaker bones and various other deficiencies. Fluorosis is dangerous especially for young children, because it can lead to them having lesser IQ, thus seriously affecting their emotional and physical growth.

 

Activated alumina water filter can very easily reduce the fluoride levels present in the water meant for drinking purposes from 10.0 ppm to less than 1.0 ppm. The amount of fluoride absorbed from the water being filtered depends on how long the water is in actual contact with the immersed activated alumina filters. If more of the activated alumina filters are in contact with the water, which is to be treated then more fluoride molecules can be absorbed. This will result in there being less fluoride in the final filtered water. Such treated water is fit for drinking as well as household purposes.

 

Lower temperature water and lowered acidic water are also filtered more effectively with the help of Activated Alumina water filter.

Activated alumina balls are aluminium oxide based compounds which are highly porous in nature with a significantly high surface-area-to-weight ratio. With the latest technology, they can easily attain their high quality properties like adsorption, mechanical strength, pore volume and surface area. The striking features of this adsorbent are its non-corrosive nature, resistance to softening and swelling, abrasion resistant, shrink proof, low resistance to gas proof, etc. An assortment of activated alumina is available in the market, which includes adsorbent, desiccant and activated alumina for chromatography.

Applications of Alumina Balls

Alumina balls act as filters in bed toppings and supports for removing any impurities from the gas stream, which helps in the uniform distribution of feed gas. In a catalyst bed, the presence of these balls keeps the bed intact during any fluctuation in pressure. It can also withstand high thermal shocks and is completely unaffected by an emergency start-up or shutdown. The alumina refractory bed support usually acts as an inert catalyst support in oil refineries, chemical industries, ammonia manufacturing plant, etc.

Uses of Activated Alumina

The inherent properties of this compound make it extremely useful in the following ways:

•    Used as a desiccant: It works through the adsorption process when being used as a desiccant. During this process, the water present in the air actually sticks to the alumina so that the dried air is passed out through the filter.

•    Used as a fluoride adsorbent: It is widely used to remove all fluoride contents from drinking water. This compound, when used in filters, can reduce the fluoride levels from 0.5ppm to less than even 0.1ppm. Depending on how long the water is in touch with alumina, the amount of fluoride can be leached from the water. Basically, more the alumina in the filter, less is the fluoride in the final filtered water.

•    Used as a catalyst: It can also be used for various catalyst applications like in hydrogen peroxide production, in the production of polyethylene, as a selective adsorbent for many chemicals, including fluoride, arsenic, etc. in sulphur removal from the main gas streams.

•    Used as a biomaterial: The non-reactivity and mechanical properties of this compound make it an ideal material for covering surfaces in friction.

Uses of activated alumina AD101

The wide range of its uses is for adsorbent purposes. But, we also find some catalytic applications of this substance at the time of producing polyethylene and hydrogen peroxide.
It is also used as a desiccant. The process, followed for its work is called adsorption. The water present in the air, sticks to the alumina when the air passes through the alumina molecules. All the water molecules are trapped and the air is dried out at the time of passing through it.

Another significant use of Activated Alumina is removing the fluoride from the drinking water. There are many places in the world where the level of fluoride in the drinking water is above the tolerance level and that can cause Fluor sis. The alumina AD101 can easily reduce the fluoride level from 5ppm to less than 1ppm. The equation is like the more alumina in the water, the less fluoride in the water.

Therefore, now you know why this alumina substance is so widely accepted in different countries in the world.
