Activated carbon filters

Activated carbon is able to retain or adsorb on its surface one or more components (atoms, molecules, ions) that are present on the fluid in contact with it. This phenomenon is known as adsorbing power. Adsorption is responsible for purifying, deodorizing and dechlorinating water, liquids or gases which are held in contact with the adsorptive element.

Its ability to retain certain unwanted compounds is based on one of its most important characteristics: it has a large specific surface (varies from 500 to 1500 square meters per gram) with an enormous amount of pores. It is the high temperatures, special atmosphere and vapor injection during fabrication, which activates and creates carbon's porosity.

Chloride and Organic matter are efficiently removed by this process, removing undesirable odors, color or flavor from water. Adsorption, mechanic filtration and catalytic reactions are the three mechanisms involved.

Activated carbon filters can be used for removal of the following contaminants:

  • Inorganic compounds
  • Chloride
  • Some heavy metals (Chromium, Mercury, Lead)
  • Tannins
  • Organic compounds
  • Chloramines
  • Volatile Organic Compounds (VOC)
  • Color-causing agents
  • Flavor-causing agents
  • THM (Trihalomethans).
