Water pollutant adsorption capacity

Activated carbon has a high adsorption capacity of a wide range of polluting organic (hydrocarbons, solvents, pesticides, odours, flavours, etc.) and inorganic (chlorine, ozone, etc.) molecules that can be found in raw water.

  • In general the effectiveness of activated carbon for water depends on:
  • Pollutant solubility in water. The lower the solubility the easier it is adsorbed by the carbon.
  • Pollutant polarity: closely related to the solubility in water.
  • Pores size of the carbon: the general rule dictates that the size of the pores must be from 1 to 5 times the size of the molecules that have to be retained.
  • The activated carbon systems are easily installed and maintained and can be combined with other processes.
