Fluoride Removal Filter Media – Activated Alumina Ceramic Balls
1. High adsorption
2. Filter impurities in water
3. Remove fluorine from water
Product Overview
Activated Alumina Ceramic Balls are a highly porous filtration media widely used for fluoride removal and water purification. The material is produced from high-purity aluminum oxide (Al₂O₃) through advanced processing methods that create a large surface area and highly developed pore structure, enabling strong adsorption capacity.
Due to its excellent adsorption properties, activated alumina is particularly effective for removing fluoride ions from drinking water, making it suitable for use in regions with high fluoride concentrations.
Activated alumina ceramic balls are also known for their high mechanical strength, chemical stability, and resistance to swelling or cracking, even after absorbing water. The material is non-toxic, odorless, and insoluble in water and ethanol, making it safe for drinking water applications.
In addition to water treatment, activated alumina is also widely used as a desiccant, air purification media, and adsorption material in various industrial and household applications.
Manufactured by Zhangqiu City Longxin Corundum Products Co., Ltd., the product is suitable for global water treatment equipment manufacturers and filtration system suppliers.
Key Features
High Adsorption Capacity
Activated alumina has a large specific surface area and porous structure, providing excellent adsorption performance.
Effective Fluoride Removal
Specially designed for removing fluoride from drinking water, helping improve water safety in high-fluoride regions.
Strong Mechanical Stability
The ceramic balls maintain their shape and do not swell or crack after absorbing water.
Safe and Non-Toxic Material
The material is odorless, insoluble in water, and safe for water purification applications.
Regenerable Adsorbent Media
After saturation, activated alumina can be regenerated by heating at 175–315°C, restoring adsorption capacity.
Multi-Functional Filtration Media
Suitable for both water purification and air drying applications.
How Activated Alumina Removes Fluoride
Activated alumina removes fluoride through an adsorption process.
The porous surface of the alumina ceramic balls attracts and binds fluoride ions (F⁻) from water. As water passes through the filtration media, fluoride ions adhere to the surface of the activated alumina, effectively reducing fluoride concentration.
Due to its high surface area and strong adsorption capability, activated alumina is one of the most widely used materials for fluoride removal in drinking water treatment systems.
