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.

In spite of having so many gas drying desiccants out there in the market, there has a strong significance why people (those who need to use these desiccants) are fond of activated alumina when it comes to dry out a warm gas appropriately. One of the prime reasons is that these balls are formulated with aluminum oxide which is highly porous and possess a tremendous surface area which let them soak up the gas and water molecules on a large scale. The surface normally ranges from 345-415 square meter/gm and this wide surface makes this element adsorb more gas, moisture, water vapor and humidity, even more than silica gel as well. For having such a higher capacity of gas consumption at an elevated temperature as well, it is an obvious choice for the various industrial purposes like; purification, isolations etc.

The alumina has a resistant power from thermal shock and abrasion, more so, they don’t get shrink, swell, soften and not even they disintegrate when completely saturated into gas. The element is formulated with aluminum hydroxide and the process is called dehydroxylation. Successful accomplishment of the process results in production of highly porous material with a huge surface area. It is made of aluminum oxide (Al2O3) and exhibits a high surface area compare to its weight and because of these, it has lots of small pores which run throughout it.

This Gas drying activated alumina is generally used for warm gases like hydrogen sulphide, sulfur oxide etc. including air as well because it has higher water absorption capacity even at a high temperature. This chemical substance doesn’t make so much of physical changes after getting immersed into gas molecules. Despite being used as an adsorbent, the activated form of alumina also possess catalyst applications in the form of alumina balls which includes the absorption of catalyst in the production of polyethylene. The utilization of activated alumina AD101 ranges from the purification (mainly removing metallic traces, TBC and HF compounds) of gases and liquids, drying out organic liquids such as LPG, propylene, butane etc.
