  • What is granular activated carbon treatment?
  • Granular activated carbon or “GAC” is a material used to filter harmful chemicals from contaminated water or air. It is composed of granules of coal, wood, nutshells or other carbon-rich materials that have been heated to “activate” the surface of the granules.
  • What type of activated carbon is used in water treatment?
  • The most commonly used activated carbon in water treatment processes is a GAC made from bituminous coal with a typical surface area of 950 – 1050 m 2 g −1 and a particle size of 12 × 40 mesh (0.420 – 1.680 mm) or 8 × 30 mesh (0.590 – 2.380 mm) .
  • 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)?
  • Granular activated carbon (GAC) is mostly used in aqueous solutions and adsorption columns for water treatment. Commercial AC is not only costly, but also obtained from non-renewable sources. This has prompted the search for alternative renewable materials for AC production.
