In the field of water treatment, activated alumina is widely used in drinking water purification, industrial wastewater treatment and removal of special pollutants due to its excellent adsorption performance, chemical stability and renewability. As an efficient and economical water treatment material, the activated alumina produced by Zibo Xiangrun performs well in removing heavy metals such as fluoride, arsenic and phosphate.
The mechanism of action of activated alumina in water treatment
Mainly remove pollutants in water through physical adsorption and chemical adsorption
● Fluoride removal
● Arsenic removal
● Heavy metal removal
● Phosphate and organic matter adsorption
Zibo Xiangrun can produce 0.5-1mm, 1-2mm, 2-3mm, 3-5mm activated alumina for water treatment, which can meet your needs.
Characteristics of activated alumina for water treatment
●High specific surface area (200-400 m²/g), providing a large number of adsorption sites.
●Strong adsorption capacity, can selectively remove pollutants such as fluorine, arsenic, heavy metals, etc.
●Chemical stability, acid and alkali resistance, suitable for different pH environments.
●High mechanical strength, not easy to pulverize, suitable for long-term use.
●Renewable, adsorption capacity can be restored by acid washing or high temperature treatment, reducing operating costs.
