In the field of modern organic waste treatment, deodorized commercial composting tanks have become indispensable core equipment. Especially in the high-temperature aerobic fermentation process, the gas composition is complex and variable, and the odor problem is particularly prominent.
How to effectively control odor pollution is not only related to environmental compliance, but also directly affects the corporate image and acceptance of the surrounding residents. Therefore, an in-depth understanding of the changing composition of fermentation gases and why an efficient deodorization system is needed becomes the key to selecting a deodorized commercial composting tank.
High-temperature aerobic fermentation refers to the rapid decomposition of organic waste at a high temperature of 55℃-65℃ through microbial activities in an aerobic environment. During this process, the main composition of the waste gas undergoes the following changes:
A large amount of carbon dioxide (CO₂) and a small amount of volatile organic compounds (VOCs) are produced with a mild odor but high water content.
Microorganisms are active, decomposing a large amount of organic matter and releasing a large amount of odor molecules such as ammonia (NH₃), hydrogen sulfide (H₂S) and methyl mercaptan, with the most pungent odor and the highest risk of pollution.
Gas emissions decrease, but some residual ammonia and organic acid-like odors are still present.
This indicates that the odor generated throughout the fermentation cycle, especially in the high-temperature main fermentation stage, is complex in composition and high in concentration, and must be treated through scientific and systematic deodorization means. Therefore, choosing a deodorized commercial composting tank with a complete deodorization system is the fundamental path to solving the odor problem.
The environmental protection act of each country has put forward a clear limit on the concentration of gas emissions. The use of ordinary composting equipment can no longer ensure that the standard, must be used with efficient deodorization system deodorized commercial composting tank.
High concentrations of ammonia and hydrogen sulfide are not only irritating, but may also cause respiratory diseases. Effective deodorization can significantly improve the air quality of the factory and reduce the employee turnover rate.
Complaints from neighboring residents and media exposure are frequent, and failure to meet environmental standards will directly damage the company’s reputation. Deploying deodorized commercial composting tanks not only passes the environmental protection acceptance, but also is an important manifestation of practicing social responsibility.
As a leading manufacturer of composting equipment in China, the deodorized commercial composting tank independently researched and developed by Bolong has comprehensively solved the problem of odors in the process of high temperature aerobic fermentation through innovative technology.
Utilizing the heat energy of exhaust gas to heat up fresh air, which is energy-saving and environment-friendly, and at the same time, lowering the temperature of exhaust gas to create favorable conditions for subsequent deodorization treatment.
Based on the traditional spray tower deodorization system for composting tanks, Bolong has launched the latest generation of gas deodorization system 5.0, which adopts a multi-stage purification process with the following advantages:
Water washing-absorb ammonia and soluble harmful substances;
Activated carbon adsorption– effective removal of volatile organic compounds (VOCs);
Biological deodorization device-microorganisms decompose residual odor to ensure that the discharged gas meets environmental standards.
Bolong’s deodorized commercial composting tanks can be flexibly combined according to different project scales to meet the diversified needs from small farms to large-scale organic waste treatment centers.
During high-temperature aerobic fermentation, the gas composition is complex and changes drastically. Only deodorized commercial composting tanks equipped with efficient deodorization systems can really meet the emission standards, improve the environmental quality, protect the health of employees, and create a green and sustainable corporate image.
In the future, Bolong will continue to help more customers to take the lead in the global environmental protection tide with smarter and more efficient deodorized commercial composting tanks.
