  • What is granular activated carbon (GAC)?
  • 1. Introduction Granular activated carbon (GAC) is a common treatment method to remove trace organics (i.e., organic compounds with a typical concentration at ng/L to μg/L level) in drinking water treatment plants.
  • 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.
  • Can granular activated carbon (GAC) expand in water?
  • Estimating the expansion of granular activated carbon (GAC) in water is complex. The incipient porosity of GAC is much higher compared to rigid particles. Combining fluidisation and characterisation experiments enables fluidisation modelling. GAC fluidisation modelling is complex but possible.
  • When was granular activated carbon used for water purification?
  • The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the “activation” process was applied to charcoal (which had been used for centuries).
