Activated Alumina Fluoride Removal

Fluoride is generally felt to be beneficial for dental health at levels up to 1.5 ppm (parts per million). However, at higher levels it has been linked to fluorosis, causing debilitating bone structure disease, as well as discoloration and mottling of teeth. Fluoride at harmful levels occurs naturally in many of the same regions as arsenic in ground water. Alcan provides ActiGuard AA400G, an activated alumina product, for fluoride removal. Due to the higher levels of fluoride as compared to arsenic, regeneration is usually required to make it cost-effective. Promoted products can be provided for applications where regeneration isn’t feasible.
