Activated Alumina

Activated alumina is a filter media made by treating aluminum ore so that it becomes porous and highly adsorptive.  Activated alumina will remove a variety of contaminants including excessive fluoride, arsenic and selenium.  The medium requires periodic cleaning with an appropriate regenerate such as alum or acid in order to remain effective.

A white or slightly red particle, ball-shaped or roll-shaped, activated alumina is insoluble in water and organic solvent. It is soluble in strong acids and alkalis, odorless, tasteless and non-toxic.
