Biotrickling odor removal for exhaust gas treatment

biotrickling odor removal is a highly efficient and economical Exhaust gas treatment technology suitable for treating low-concentration and large-volume organic exhaust gases, especially malodorous gases. This technology utilizes microorganisms to degrade organic pollutants and has the following advantages:

• High removal rate: biotrickling odor removal can achieve a removal rate of over 95% for various organic pollutants, including volatile organic compounds (VOCs), hydrogen sulfide (H2S), and ammonia (NH3).

• Low operating cost: The main operating costs of biotrickling odor removal are power and water costs, which are lower than those of other Exhaust gas treatment technologies.

• Simple maintenance: biotrickling odor removal systems have a simple structure and are easy to maintain.

• No secondary pollution: biotrickling odor removal does not generate secondary pollution.

The basic principle of a biotrickling odor removal system is as follows: The exhaust gas comes into contact with the biofilm attached to the packing material as it passes through the packing layer. The microorganisms in the biofilm degrade the organic pollutants in the exhaust gas into harmless carbon dioxide and water. Key components of a biotrickling odor removal system include:

• Packing: The packing provides support for the growth of biofilm. Common packing materials include plastic sheets, ceramic balls, and activated carbon.

• Biofilm: Biofilm is composed of various microorganisms that have the ability to degrade organic pollutants.

• Exhaust gas distribution system: The exhaust gas distribution system distributes the exhaust gas evenly throughout the packing layer.

• Nutrient solution supply system: The nutrient solution supply system provides the necessary nutrients for the biofilm.

• Exhaust system: The exhaust system discharges the purified gas into the atmosphere.

biotrickling odor removal has a wide range of applications in the following fields:

•  Food processing industry: The waste gas generated by the food processing industry contains a large number of organic pollutants, such as volatile organic compounds, fats, proteins, etc., which can cause odor and pollution. Biological trickling filtration deodorization can effectively remove these pollutants and improve the workshop environment.  

• Chemical industry: The waste gas produced by the chemical industry contains a large amount of organic pollutants, such as benzene, formaldehyde, ethylene, etc., which are toxic and carcinogenic. Biological trickling filtration deodorization can effectively remove these pollutants and reduce environmental pollution.  

• Pharmaceutical industry: The waste gas generated by the pharmaceutical industry contains a large number of organic pollutants, such as antibiotics, hormones, etc., which can cause environmental pollution. Biological trickling filtration deodorization can effectively remove these pollutants and protect the environment.  

• Municipal sanitation: Waste gases generated by municipal sanitation include methane generated by landfills, odorous gases generated by sewage treatment plants, etc. Biological trickling filtration deodorization can effectively remove pollutants in these exhaust gases and improve environmental quality.
