Activated Carbon

Activated carbon is a form of pure carbon which is constituted in such a way as to have a network of pores within its structure.  It is an extremely versatile agent for the extraction of organic compounds from liquid or gaseous streams.

The media can be supplied as:

  • Powder activated carbon, known as PAC
  • Granular activated carbon, known as GAC
  • Pelletised activated carbon

Each of these forms has specific applications, and the choice will depend on the user's circumstances.


Typical uses for activated carbon include:

  • Potable water purification
  • Waste water purification
  • Air purification
  • Odour removal
  • Taste removal
  • Colour removal
  • Removal of other unwanted organic compounds
  • Extraction of desirable materials from solution (e.g. gold cyanide)
  • Sugar refining
  • Glucose refining
  • Separation of organics from industrial solutions
  • Reduction of emissions
