The so-called odor is nothing more than a special flavor of volatile organic compounds, your source of odor of this project may have two aspects, one is the hydrolysis acidification process produced by volatile organic acids or hydrogen sulfide, the second is the contact oxidation process with the aeration of the air flow out of the odor with the odor of the organic matter. Process adjustment is not worth the loss, Roots fan frequency reduction if the power of the air volume will also be reduced, the result may cause insufficient oxygen supply, treatment does not meet the standards, the lack of oxygen under the conditions of the odor may be even greater, it is not recommended to adjust the process or air volume.
The principle of deodorization, or the nature of the odor is volatile organic compounds, can be used similar to biological droplet filter tower so that the use of biological degradation of organic deodorization devices, can also be used in activated carbon adsorption, such as adsorption of such organic compounds, depending on the circumstances of your decision. In addition, because your treatment station is very close to residential buildings, be sure to hydrolysis acidification pool in addition to the exhaust hole sealed. Typed so many words, I hope to be useful to you.
