Active carbon filter

Active carbon filter

Purpose of use
  • Removes a variety of pollutants (NOX, Sox, HC), exhaust fumes, harmful gases and odors from various equipment, smoke and other odors; prevents corrosion and chloride attack in measuring instruments, communication equipment, computers, precious metals, removes the organic solvent components.
Types of active carbon

  • Pelletized Activated Carbon

    It has a high adsorption rate. It is mainly used for high concentration gas treatment.

  • Granular Active Carbon

    It is used the most extensively as it retains a large surface area and when fixed and stationary, sees a small pressure drop while being capable of recovering the adsorbed substances relatively easily.

  • Activated Carbon powder

    Inexpensive price, its quality is inferior to that of granular carbon, which causes an excessive pressure drop when used in a packed tower, leading to many limitations in usage.

Activated carbon adsorption process
  • Stage where the adsorbate molecules move to the outer surface of the adsorbent.
  • Stage where the adsorbate passes through the macropores and mesopores of the activated carbon.
  • Stage where the diffused adsorbate combines with or fills the inner surface of the micropores.
