For effective VOC separation using activated charcoal, thanks to the large filter surface.

Activated charcoal filter

VOC / odour reduction

Odour emissions are not only unpleasant and annoying – they can also be harmful to health. Volatile organic compounds (VOC) or inorganic compounds such as hydrogen sulfide (H2S) and ammonia (NH3) are the culprits here. There are maximum levels of such components in exhaust air, which must be observed. The odour threshold is much lower than the threshold, however, meaning that minimal concentrations still cause considerable odour pollution. Activated charcoal effectively reduces these components. The exhaust airflow is guided through an activated charcoal bed at low speed. The activated charcoal adsorbs the hazardous substances from the exhaust air and binds them to its surface.

Advantages for you

  • Low investment costs
  • Functionality under varying operating conditions
  • Guaranteed compliance with required exhaust air values
  • Low maintenance

Features

  • Adsorption of organic pollutants and odorous substances in the exhaust air
  • Not sensitive to fluctuating process conditions
  • Long lifetime thanks to robust design
  • Securely and continuously below thresholds
  • Optional filter breakthrough monitoring

Application
Odour reduction of the dryer exhaust air of a fish meal sterilization process by means of injection of plasma-enriched air by the COPLAS clean technology and downstream activated charcoal filter. The goal was to replace an existing exhaust air cleaning system (corona discharge) and at the same time to counteract emerging complaints from the neighborhood.

Equipment
Process combination of the COPLAS clean system and an activated carbon bulk filter for the treatment of exhaust air with an odour concentration of 300,000 GE/m³

  • Air volume: up to 800 m³/h
  • Fan: up to 900 m³/h
  • Bag filter as pre-filter for cleaning the smallest particles of the fresh air
  • HMI for user-friendly operation
  • Prevention of backflow of exhaust air into our system
  • Activated charcoal filter: 1 ton of activated charcoal with a flow rate of 0.3 m/s incl. big bag station

Features

  • Treatment of small volume flow with very high odour concentration with discontinuous process
  • High concentration of VOCs / amines
  • Reduction performance of COPLAS clean technology of > 90% plus activated charcoal filter for further reduction
  • Odour reduction: 100% reduction of typical raw gas smell
