Activated Alumina is used as a fluoride remover for high-fluoride water. The conventional particle size is 1-3mm,2-4mm. When in use, it has a large contact area with water, a specific surface area of up to 320m2/g or more, and a large number of micropores, which can ensure a strong adsorption capacity for fluoride ions in water and a high fluoride removal capacity. When the PH and alkalinity of the raw water are low, the fluoride removal capacity is high, greater than 4.0mg/g. It can also be used for arsenic removal in drinking water.

Activated Alumina ball can used in below items

① Activated Alumina can be used for fluoride removal in drinking water or in other industrial devices for fluoride removal, arsenic removal, sewage decolorization, deodorization, etc.

② Activated Alumina can filter out pollutants in water, such as arsenic, copper, lead, phosphate, etc

③ Activated Alumina can be used as a defluorinating agent for circulating alkanes in the production of alkylbenzene

④ Activated Alumina can be used as Arsenic removal agent in the acid production industry

Controlling the pH, pre-treatment water quality, selecting appropriate adsorbent parameters and optimizing operating conditions (such as duration of contact and flow rate) can effectively enhance the fluoride removal effect of activated alumina. In practical applications, the process needs to be adjusted specifically according to the characteristics of water quality to achieve the ideal fluoride removal efficiency and cost control
