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 basically made up of Aluminium Oxide which is highly porous and exhibits tremendous surface area. Being supplier of Activated Alumina Balls we provide material which is resistant to thermal shock and abrasion. Moreover it will not shrink, swell, soften nor will disintegrate when immersed in water. The main advantage using Activated Alumina Balls is its high surface area about 345-415 m²/gm and attrition loss is very less about 0.2 % having crushing strength of 8-12 kgf/cm².

Activated Alumina is being very effective when used as water filter. Water having various impurities and contents should be filtered in order to prevent any harmful disease in human beings. The main concern is to control access amount of Fluoride contents in water. Fluoride compounds are basically salts that form when the element fluorine combines with minerals in soil and rocks. Excessive amount of fluoride in drinking water would result into several diseases leading to bone fracture in adults, tooth decaying etc.

Activated Alumina Balls thereby being used as water filtration to remove access fluoride contents from water. Permissible limit of fluoride content is about 1.5 mg/litre so activated alumina balls manufactured by us can be very useful in reducing fluoride contents.

Being supplier and manufacturer of Activated Alumina Balls we mainly focus on quality of material thereby try to keep customers happy and satisfied. We have long client list of customer to whom we provide Activated Alumina on regular basis.

ACTIVATED ALUMINA BALLS?? WHAT IS IT??

Activated Alumina Balls is basically made up of Aluminium Hydroxide by dehydroxylating it which produces highly porous material. This will have high surface area around 345-415 m²/gm.

Activated Alumina Balls is widely preferred due to its varied application and its high adsorption capacity. Activated Alumina Balls is used for a wide range of Adsorbent and Catalyst application such as adsorption of polyethylene production, in hydrogen peroxide productions and also for removing access amount of Fluoride and Arsenic contents from water.

Activated Alumina when used as desiccant, the process is called Adsorption. The air passes through alumina balls where the water that is present in the air gets sticked in alumina through the tiny passages through them, thus water molecules get trapped & thereby the air is dried out and passes through the filter. On regeneration desiccant i.e. by heating to -200°c it would release trapped water.

Mostly Activated Alumina Balls is being used in Air Dryer/Desiccant Dryers namely Heatless Air Dryer, Heat of Compression Air Dryer and Heat Re-activated Air Dryer. Activated Alumina Balls would absorb moisture present in the Air and thereby would give dry air and is suitable of acquiring Dew Point of -40°c. It would be advisable that the bed should be compactly filled so to avoid air passing without being in touch with Alumina Balls.

Activated Alumina Balls is also used for reducing access amount of Fluoride and Arsenic contents from water. Activated Alumina Balls has capacity of reducing fluoride contents up to 0.1 ppm.

ACTIVATED ALUMINA BALLS is widely accepted as the best and most cost effective adsorbents for removal of Fluoride contents from water. It is currently used to treat potable water for municipal and household units as well as remediation of waste streams.

Activated Alumina Balls used to water treatment is an aluminum oxide that is highly porous and has high surface area. The crystal structure of alumina contains cat-ion lattice discontinuities giving rise to localized areas of positive charge. This makes alumina attract various anionic species. Activated Alumina Balls manufactured by us does not shrink, swell, soften nor disintegrate when immersed in water.

Activated Alumina Balls used for water treatment has minimum adsorption capacity of adsorbing fluoride content up to 2.85 mg F/g of Alumina. We are globally recognized as manufacturer of premium quality industrial chemicals like adsorbents for water treatment for removal of Fluorides & Arsenic of ground water & waste water.

Fluorides are found in the waste discharges from process streams in a number of industries so it becomes necessary to reduce its harmful effects the leveling down its content below 1 ppm. In certain regions of India such as Jaipur, West Bengal and Karnataka there is enough fluoride in the water to cause fluorosis so Activated Alumina Balls that we manufacture can easily reduce fluoride levels from 8-10 ppm to less than 0.1 ppm.

Activated Alumina Balls manufactured by us when used for Water Treatment can be regenerated by a solution of sodium hydroxide, Hydrochloric acids, Sulfuric acid or alum.
