Odor removal

Odor removal

The term odor removal describes the removal of strongly odor-contaminated aerosols, smoke and particles from the production exhaust air. Strong odor contamination occurs particularly in the food and rubber industry as well as in metal processing and in the production of pharmaceutical products. In order to prevent such odors from having a negative impact on the environment or people, national legal requirements place high demands on production plants concerning pure air quality and VOC content. Exhaust air purification is subject to strict legal requirements.
Therefore, a comprehensive odor removal is an absolutely essential part of exhaust air purification. For production plants there are various possibilities to remove odors from the exhaust air stream. In addition to conventional methods such as thermal oxidation, e.g. thermal, regenerative or catalytic oxidation, other processes are used depending on the intensity and composition of the odorous exhaust air. For an energy-efficient and high-grade extraction, a flexible combination of a gas scrubber, bio filter, activated carbon filter or UV light module is possible. The modular design of the KMA exhaust air filtration systems allows an individual composition and placement of these modules according to the production exhaust air. This ensures optimum odor removal.
Depending on their design and composition, KMA filtration systems achieve an odor removal of well over 90%, i.e. the extraction reaches the quality level “no product-specific odour at the property boundary”. Furthermore, exhaust air filtration systems by KMA Umwelttechnik are extremely energy-efficient – to purify an exhaust air volume of 5,000 m3/h an electrostatic precipitator cell requires the approximate energy consumption of a 100 W light bulb.
