Activated carbon filtration


Filtration using granular activated carbon (CAG) is a very common step in industrial or potable water production from groundwater or surface water. 

CAG improves quality by eliminating :

  • Compounds at the origin of tastes and odors
  • Pesticides
  • Colour
  • Total organic carbon
  • Trihalométhanes and disinfection products
  • Chlorinated hydrocarbons and other volatile organic compounds (COV)
  • Endocrine disruptors
  • Drug and daily residues

Residual free chlorine can be reduced into harmless chloride by means of activated carbon.

It’s a very effective solution for chlorine removal before a reverse osmosis system.

In contact with activated carbon, chlorine reacts as follow :

C + 2 Cl2 + 2 H2O → 4 HCl + CO2
