Activated Alumina

Activated Alumina

Activated alumina is a porous material made from aluminum oxide that is highly effective at removing impurities from gases and liquids. It is created by heating aluminum hydroxide to a high temperature, which removes any bound water and creates a highly porous material with a large surface area.

The high surface area of activated alumina allows it to effectively absorb and adsorb impurities, including water, fluoride, arsenic, and other contaminants. It is commonly used in a range of industrial applications, including water treatment, gas purification, and catalysis.

Activated alumina is available in a range of sizes and shapes, including beads, pellets, and granules, and can be tailored to specific applications based on its pore size and surface area. It is known for its high strength and durability, even in harsh environments, and can be easily regenerated and reused.

In water treatment, activated alumina is commonly used to remove fluoride, arsenic, and other contaminants from drinking water. In gas purification, it is used to remove impurities from natural gas, air, and other gases. In catalysis, it is used as a support material for catalysts in chemical reactions.

Overall, activated alumina is a versatile and effective material that offers unique properties for a range of industrial applications. Its high surface area, durability, and effectiveness make it a popular choice for use in industries such as water treatment, gas purification, and catalysis.
