Activated Alumina

Activated Alumina
Activated alumina is a type of aluminum oxidant in the form of very porous spheres literally “tunned” at the microscopic level and has a very high surface area. Activated alumina is mainly used for adsorption of gases in liquids. Adsorption is the adhesion of one substance to the surface of another substance. Activated alumina performs this adhesion process very effectively and is therefore used very often. Drying of gases is often vital for the safe transport of volatile gases. Gases such as propane must be dried before use to prevent equipment corrosion that can lead to dangerous leaks.
Activated alumina is used for a variety of industrial applications. For example, it is used in air cleaners to improve air quality. Besides, activated alumina is also used for the removal of chemicals and fragrances. Activated alumina, which is prepared with a special formulation, can also prevent the proliferation of microorganisms in liquids, thus helping to prolong the life of liquids.
 
Usage areas
Activated alumina is used in a variety of industrial and commercial applications due to its high surface area and ability to adsorb gases and other substances. Some of the common uses of activated alumina include:
 
Air purification: Activated alumina is used in air cleaners to remove impurities and pollutants from the air.
 
Water purification: Activated alumina is used to remove impurities and contaminants from water such as arsenic and fluoride.
 
Chemical production: Activated alumina is used as a catalyst in the production of chemicals such as plastics, resins and pharmaceuticals.
 
Oil refining: Activated alumina is used to remove impurities in petroleum products.
 
Gas drying: Activated alumina is used to dry gases such as natural gas to remove water vapor and other impurities.
 
Food and beverage production: Activated alumina is used to remove impurities and improve the quality of food and beverages.
 
Industrial gases: Activated alumina is used to purify industrial gases such as hydrogen and oxygen.
 
Medical applications: Activated alumina is used in the manufacture of medical products such as dialysis filters.
 
Types of Activated Alumina
 
Different types of active alumina, depending on the need and the size of the molecules to be separated:
 
Dryer Grade Activated Aluminas
Fluoride Removal Grade Aluminas
Absorbed Potassium Permanganate Aluminas
            a.4% absorbed KMnO4
 
            b.8% absorbed KMnO4
 
            c.12% absorbed KMnO4

1. Dryer Grade Activated Aluminas

 It is the perfect dryer for drying a wide variety of liquids and gases. Uniform ball size is particularly useful in high pressure gas dehydration where it is important to minimize the pressure drop and the special pore distribution provides high dynamic H2O adsorption capacity.

2- Fluoride Removal Grade Aluminas

 

• Lowest cost per 1,000 gallons due to high capacity and low cost per cubic foot. It is a solid material and does not deteriorate with backwashing.

 

• Works in a wide variety of water chemistry.

 

• Iron levels do not affect arsenic capacity.

 

• Disposable, disposable without any hazardous waste.

 

• Certified to NSF/ANSI standard 61 and successfully completed an EPA ETV project.

 

• It is an adsorbent for metals containing fluoride.

 

• Drinking water regeneration is normally used to operate at the most cost-effective levels.

 

• Fluoride grade is used to simultaneously reduce fluoride and arsenic to acceptable levels in a treatment.

3- Absorbed Potassium Permanganate Aluminas

It is a spherical, active alumina-based medium impregnated with potassium permanganate (KMnO4). It is ideal for applications where activated carbon is ineffective, such as the adsorption of polar or low molecular weight compounds. Due to its spherical form it is suitable for use in various types of panel filters as well as in applications where lower pressure drop is required. The potassium permanganate concentration is higher than other similar products, thus providing a longer service life.
