Granular activated carbon is defined as the activated carbon being retained on a 50-mesh sieve. Chemviron’s produces Granular activated carbons designed to meet and exceed the demands from water treatment to gas phase applications, and from the purification of other aqueous and organic liquids to the treatment of cane sugar liquors and much
Powdered activated carbons (PAC) are used in batch treatment processes, whereas granular (GAC) grades are generally used in fixed filter beds, with the water passing through the filtration medium. The advantage of using GAC for water treatment is that the spent carbon can normally be regenerated via thermal reactivation.
