Activated alumina is an outstanding desiccant used to dehumidify compressed air and liquid streams. Furthermore, its water filtration properties make it an effective means of eliminating fluoride and arsenic from drinking water supplies. Filters can remove lead and silica from water to protect consumers against health complications that could arise from long-term consumption of these contaminants.
Activated alumina is an extremely durable material that can serve many different applications. The activation process creates micropathways to give it a high surface area with large porosity for adsorption and catalysis purposes.
Material that binds with different substances without altering its chemical structure or form. This makes it an effective catalyst in chemical reactions as well as being utilized for water treatment, desiccation, dehydration and purification.
Pressed into a powder form, activated alumina has an impressively high crush strength when compressed into powder form, which enables it to perform effectively in adsorption applications. Furthermore, its granules do not expand under high pressure conditions and thus remain intact and do not disintegrate or expand over time.
This spherical alumina is produced through an innovative process and contains high levels of boehmite for superior mechanical strength and crush resistance compared to standard small alumina spheres of similar size.
Activated alumina can be utilized in many water treatment applications, including fluoride removal, color and odor reduction, iron and phosphate removal and industrial applications. Its primary use as a filter media to remove harmful contaminants such as fluoride, lead, arsenic and other metals is filter media applications; regeneration of this material using suitable chemicals makes reuse convenient and economical.
Activated alumina ball is an extremely porous material with various pore sizes that makes it an excellent adsorption material. Both its surface area and pore sizes facilitate absorption from various liquids and gases; its ability to do this relies largely on its chemical makeup which includes aluminium oxide (Al2O3) as its core.
Aluminum atoms in alumina spheres bond to molecules of substances to be removed, creating an adsorption process which is reversible; when heated at high temperature, molecules are released back into their respective spheres. Furthermore, activated alumina has outstanding crash tolerance properties and is suitable for fixed bed applications with high contaminant loads.
Due to its adsorption properties, activated alumina is an invaluable element of water filtration systems. It's often employed in the removal of fluoride, arsenic and selenium from drinking water sources; additionally it serves as a desiccant to keep compressed air or gas streams dry.
Active Alumina can also be utilized as a catalyst in the Claus process for desulfurizing natural gas, acting to remove volatile organic compounds such as benzene, toluene and xylene from industrial production processes and water filtration applications. Furthermore, when applied as filter media in water treatment systems activated Alumina is known for efficiently filtering fluoride and arsenic from drinking water supplies.
Foulant deposition occurs when substances from a process fluid adsorb or adhere to the surface of a porous membrane or solid media, forming deposits. Attachment may result from adsorption, dissolution, chemical reactions or physical processes such as particle collision, inertial coasting/impaction for particles of finite sizes; turbulent-eddy and molecular diffusion, Stefan flow (for condensation and evaporation); electrophoresis diffusiophoresis or thermal effects. Foulant removal involves deposit dissolution; re-entrainment of detached particles or removal by deposits spalling or erosion wear-off.
Fouling in the process industry often occurs due to particulate matter that becomes trapped either within membrane pores or cake layer, and can easily be remedied using simple cleaning procedures without adversely impacting stack performance.
Fouling from NOM and biofilms is often irreversible, with its severity depending on both their physiochemical characteristics as well as interactions between these foulants and membrane charged groups. This type of fouling typically manifests itself by the formation of inorganic deposits on membrane surfaces consisting of carbonates, silicates and phosphates deposited as crystals or colloidal flakes - something seen commonly in oil & gas and food processing industries where many process fluids contain fatty acids or hydrocarbons as part of process fluid composition. This type of fouling occurs quite regularly in systems using process fluid containing significant volumes fatty acids or hydrocarbons such as found in oil & gas processes containing significant volumes of process fluid with respect to system performance.
Activated alumina ball is widely recognized for its superior strength, thermal stability, and absorption capabilities, which make it popularly utilized as an absorbent, desiccant and catalyst carrier in various industries including petrochemical, oil & gas and fertilizers.
Activated alumina differs from other porous substances like sand in that its pores do not simply absorb chemicals and liquids; rather, its molecules actually bond with what it draws in through its pores - this property makes activated alumina an effective way of filtering contaminants like fluoride, lead, arsenic and selenium from drinking water supplies.
Adsorption properties of activated alumina are attributable to its high surface area-to-weight ratio, created through controlled activation processes that involve heating aluminum hydroxide to dehydroxylation. Furthermore, activation procedures allow manufacturers to tailor porosity and pore structures according to final applications of activated alumina materials. Given these characteristics, activated alumina is highly durable and can be recycled multiple times for reuse. Regenerating activated alumina also significantly lowers operational costs and environmental impacts while its absorbent capabilities, thermal stability and durability make it a popular choice in petrochemical, petroleum, gas, and fertilizer industries.
