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.
