Definitions

  • the most common method used hitherto for the reduction of emissions into air and water recipients is based on adsorption, with activated carbon as the adsorbent.
  • the contaminated liquid or gas is caused to flow through a filter in which the activated carbon is either present in the form of a bed or is provided on a carrier sub- strate.
  • the activated carbon may also be used in a fluidized bed system, with the contaminated liquid or gas flow constituting the fluidizing medium.
  • the adsorbent may comprise any inorganic material what ⁇ soever which is capable of withstanding those temper ⁇ atures at which regeneration of the adsorbent takes place in accordance with the invention.
  • Suitable mate ⁇ rials in this respect include hydrofobic or hydrophilic zeolites in pellet or powder form.
