Activated carbon properties

Activated carbon is a non-hazardous carbon-bearing product with a porous structure and a very large internal surface area. The chemical structure of activated carbon can be defined as a crude form of graphite, with a random amorphous structure that is highly porous over a range of pore sizes, from visible cavities and gaps to those of molecular dimensions.



Treatment with activated carbon is based primarily on the phenomenon known as adsorption, in which molecules of a liquid or gas adhere to an external or internal surface of a solid substance. Activated carbon has a very large internal surface area (up to 1,500 m²/g) which makes it highly suitable for adsorption. Activated carbon can be impregnated with certain chemicals in order thus to enhance its properties for certain applications.

Water and liquid applications for:

  • municipal drinking water treatment (taste, odour and micro pollutant removal e.g. pesticides, …),
  • domestic water treatment (in-line and cartridge filters),
  • process water (de-chlorination and de-ozonation),
  • ground water remediation,
  • waste water treatment – tertiary treatment (trace organics and COD removal, deodourisation and decolourisation, powdered as bio-flock improvement in an aerobic or anaerobic biological waste water treatment plant, as an additive for physical- chemical treatments),
  • raw material purification (purification of oils and fats, alcoholic and softdrinks, dyestuffs, …, decolourisation of sugar and glucose, food, chemicals, pharmaceuticals) and
  • catalytic processes.

Air and gas applications for:

  • air purification and environmental protection (removal of solvents and hydrocarbons, deodourisation, air conditioning, cooker hoods, flue gases, in powdered form the removal of dioxins, mercury and other trace elements from flue gases),
  • cleaning process gases (removal of contaminants from hydrogen, natural gas, carbon dioxide, landfill gas, solvent recovery, …),
  • respiration protection (gas masks, removal of harmful of toxic compounds),
  • tank venting,
  • ground water remediation,
  • molecular sieves.
