EFFECTIVE REMOVAL OF FLUORIDE AND ARSENIC
Granulated aluminum oxide is called activated alumina. This method involves passing contaminated water through an activated alumina filter, which absorbs the impurity.
The U.S. Environmental Protection Agency (EPA) has designated activated alumina as a "best available technology" (BAT) for the removal of fluoride and arsenic. Granular activated alumina is a cost-effective, regenerable substitute for alumina in applications including arsenic and fluoride.

Applications for activated alumina in industry
Activated alumina provides a polishing stage for industrial waste water, as health concerns about fluoride and arsenic are growing. The semiconductor sector, glass manufacturing, steel and aluminum processing, pesticide and fertilizer manufacturing, and other production processes frequently use arsenic and fluoride.

Among the benefits of activated alumina filters are:
A practical method for lowering fluoride, arsenic, and selenium levels
Among the drawbacks of activated alumina filters are:
Reducing levels of additional toxins of health concern would require the employment of alternative treatment techniques.
