Imagine an invisible sponge soaking up impurities like fluoride, arsenic and selenium from your water system; that is the role played by activated alumina in industrial applications to ensure product quality and public health.
Activated alumina is created through controlled heating of hydrated alumina to expel water molecules and form distinct porous structures. Regenerative and withstanding high temperatures, activated alumina makes an excellent material choice for applications requiring heat.
Selective Adsorption
Activated alumina has an exceptional capacity to absorb moisture and other impurities from its porous structure, as well as selectively binding certain substances while rejecting others – qualities which make it useful in applications like fluoride removal, arsenic treatment, color and odor elimination, as well as phosphate removal from water sources.
Activated alumina’s low pH and alkalinity make it an effective choice for arsenic removal from groundwater, with its ability to adsorb arsenic without changing taste or smell. As its capacity may be diminished by high pH or bicarbonate alkalinity levels in water sources, pre-treating with salt regenerated strong base anion resin (SBA resin) prior to using an alumina polisher is recommended to ensure the greatest success rate possible.
Fluoride in water can be beneficial at levels up to 1.5 parts per million (ppm), but excess fluorosis has been linked with debilitating bone structure disease and discoloration of teeth. Alcan’s DI-tech AA400G product for iron enhanced activated alumina can remove fluoride at a cost competitive with other technologies.
Activated alumina is chemically inert and highly resilient against chemicals, gases, and temperatures. Videre, this material is highly regenerative allowing long-term usage without suffering significant degradation of performance.
Høy overflate
Activated alumina’s surface area is immense, enabling it to quickly absorb particles and impurities without losing effectiveness in this capacity. Like an efficient “sorting process”, activated alumina acts like an effective magnet by drawing specific molecules towards itself while leaving others behind – an ability that makes it an indispensable ingredient in industrial processes like air separation, natural gas dehydration and petrochemical purification.
Alumina’s adsorption capabilities are further complemented by its capacity to retain dissolved water, making it useful in applications like fluoride removal from drinking water and protecting delicate equipment from damage. Unlike silica’s surface which is fully hydroxylated, which limits how quickly water seeps into its pores; instead alumina has large porous structures which absorb and store moisture within.
Moisture’s damaging impact on various industrial processes makes activated alumina an indispensable component. By mitigating moisture’s harmful effects on operations, activated alumina helps companies avoid costly product degradation or equipment failure due to moisture, particularly compressed air drying applications. Videre, activated alumina plays an integral part in natural gas dehydration, helping prevent the buildup of harmful contaminants during transport and storage.
Activated alumina has numerous uses in food-grade dehumidification systems and businesses alike; it helps preserve potato chip crunchiness while prolonging product lifespan, dehumidifying systems and even deodorization systems. Videre, Hengye Inc provides comprehensive guidelines for using activated alumina material in various industrial settings.

High Porosity
Activated alumina’s unique structure features numerous pores that allow gas and liquid molecules to pass quickly through. This makes it a highly effective adsorbent suitable for numerous applications.
Fluoride, arsenic and phosphate can all be easily eliminated from water with activated alumina adsorption systems. Phosphate can be easily adsorbed by activated alumina at concentrations up to 10 ppm in fixed bed mode (C0 = 100 ppb; pH 6). Arsenic adsorption by activated alumina is significantly stronger than with fluoride removal being accomplished with low pressure at 200-200 degC using NaOH in vapor phase [20]
Activated alumina makes for an effective air and gas purifier and desiccant, protecting valuable equipment from moisture-related corrosion while improving operational efficiency in the oil and gas industry by minimizing downtime related to moisture-related equipment failure.
Personal protective equipment must always be worn when handling activated alumina, including safety goggles or face shields, chemical-resistant gloves and a respirator or dust mask. Videre, it’s crucial to store activated alumina in a dry location with adequate ventilation away from incompatible substances that could exacerbate irritation to eyes and skin while potentially increasing respiratory risks; compatibility tests should also be run prior to incorporating activated alumina into specific processes.
High Density
Activated alumina stands out among other porous materials by its exceptional capacity to absorb high volumes of moisture through its network-like porous structure and low bulk density.
Activated alumina is one of the most versatile materials when it comes to industrial applications involving moisture adsorption. From maintaining freshness in potato chips to protecting purity of gas and liquid streams in chemical manufacturing facilities, activated alumina serves a range of essential tasks with ease.
Activated alumina serves as an exceptional “sorting process,” capable of quickly and reliably distinguishing molecules and selectively adsorbing those that should be removed. Its exceptional selective absorption capability has proven useful for applications including air separation, natural gas dehydration and chemical manufacturing.
Activated alumina has the capability of absorbing both organic and inorganic pollutants, decreasing their impact on the environment. This ensures water systems and other environmental areas remain free from toxic and chemical-laden materials – helping promote public safety while meeting stringent regulatory standards.
