Product Overview
Activated Alumina Ceramic Ball is a highly porous adsorption material produced from high-purity aluminium oxide (Al₂O₃). Through special activation processing, the alumina develops a large specific surface area and well-developed pore structure, giving the product excellent adsorption capacity for moisture, gases, and dissolved contaminants.
Due to its strong adsorption performance and stable physical structure, Activated Alumina Ceramic Ball is widely used in water purification, fluoride and arsenic removal, industrial water treatment, compressed air drying, gas purification, and desiccant applications. The ceramic balls maintain good mechanical strength during use and do not easily swell, crack, or lose structural stability after water absorption.
For drinking water related applications, Longxin uses food-grade raw materials to support safe and reliable use in filtration systems. Manufactured by Zhangqiu City Longxin Corundum Products Co., Ltd., Activated Alumina Ceramic Ball offers stable quality, long service life, and flexible packaging options for global water treatment and filtration system manufacturers.

How It Works
High Adsorption Capacity
Activated Alumina Ceramic Balls contain a highly porous structure and large specific surface area, allowing the material to adsorb moisture, gases, fluoride, arsenic, sulfur compounds, and other selected contaminants from water and air streams.
Water Purification Performance
In water treatment systems, activated alumina is commonly used to adsorb dissolved contaminants such as fluoride and arsenic, helping improve drinking water safety and overall water quality.
Gas and Air Drying
Activated alumina can remove water vapour from compressed air and industrial gases, making it suitable for desiccant systems, air drying equipment, and industrial gas purification processes.
Stable Ceramic Structure
The ceramic balls maintain stable physical structure during adsorption and are not easy to swell, crack, or break under normal operating conditions.
