  • 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) .
  • What is granular activated carbon (GAC)?
  • Granular activated carbon (GAC) is used in drinking water treatment plants worldwide to remove micro-pollutants such as pesticides. Early breakthrough of problematic micro-pollutants leads to frequent and costly thermal regeneration off-site. A potential alternative approach is to chemically regenerate GAC o
  • What is granular activated carbon used for?
  • It is primarily used for the reduction of chlorine and related contaminants from the incoming water supply. Granular Activated carbon improves the taste, colour and odour of water and is used to great effect in a wide variety of applications including drinking water, hot beverages such as tea and coffee as well as postmix drinks.
  • 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).
