  • What are the different mesh sizes for granular activated carbon (GAC)?
  • Common mesh sizes for granular activated carbon (GAC) include 8×30, 12×40 and 20×50, where the two numbers indicate the range of mesh sizes through which the carbon particles will pass. For example, an 8×30 mesh activated carbon will pass through an 8 mesh sieve but be retained on a 30 mesh sieve.
  • Does granular activated carbon adsorbent work in drinking water?
  • Drinking Water and Health: Volume 2. This chapter contains the findings of the Subcommittee on Adsorption of the National Research Council's Safe Drinking Water Committee, which studied the efficacy of granular activated carbon (GAC) and related adsorbents in the treatment of drinking water.
  • What is granular activated carbon (GAC)?
  • As well as coming in granular form (GAC), activated carbon is also available extruded as a pellet and pulverised as Powdered Activated Carbon (PAC). GAC is utilised in drinking water treatment by installing it in a fixed bed adsorber constructed of concrete or steel.
  • What is the difference between 8x30 and 20x50 carbon?
  • An 8x30 mesh carbon is approximately 2mm in diameter. A 12x40 measures about 1mm and a 20x50 mesh is about use shallower beds. The rate of reaction of a 12x40 mesh is twice that of an 8x30 mesh of the same product and a 20x50 mesh is twice as fast as the 12x40. Deep beds (6-10 ft deep) might choose the 8x30 product.
