“CLEANING THE WORLD WITH ACTIVATED CARBON”

activated alumina for fluoride
and heavy metal removal
GC Filtral is a granular activated alumina designed for the removal of fluoride and other heavy metals from water. Highly adsorbent, the GC Filtral is able to adsorb as much as 1.4g fluoride per 100g alumina with less than 1 ppm fluoride evident in the water effluent. Conditioning of the GC Filtral with dilute aluminum sulfate prior to use greatly enhances performance. The adsorbent needs only to be contacted for one hour with 29g/L of aluminum sulfate (Al2(So4)3,18 H2O) solution and it is ready for use.
The GC Filtral is available for sale in bulk or in 55, 85 and 110 gallon treatment units. These filters come complete with internal plumbing and are ready for installation. If larger flow rate systems are needed, please contact our office.
