What impacts will the long-term use of VHP pass boxes have on the environment?

Long-term use of VHP (vaporized hydrogen peroxide) transfer Windows may have the following impacts on the environment:
Residue of chemical substances
Some hydrogen peroxide may remain during the disinfection process. Although hydrogen peroxide itself is relatively easy to decompose into water and oxygen, if the decomposition is incomplete, the remaining hydrogen peroxide may cause certain chemical pollution to the environment around the transfer window.
In addition, to enhance the stability and disinfection effect of hydrogen peroxide, a small amount of stabilizer or other auxiliary components may be added to the hydrogen peroxide solution used in some VHP transfer Windows. These substances may also remain after disinfection, potentially having an impact on the environment.
The impact on microbial communities
The main function of the VHP transfer window is to kill microorganisms. Long-term use may have an impact on the microbial community structure in the environment where the transfer window is located. It not only kills harmful pathogenic microorganisms but may also inhibit or kill some beneficial ones, thereby disrupting the ecological balance of microorganisms in the environment.
The change in the structure of this microbial community may affect the ecological functions such as the self-purification capacity and material circulation of the environment, and thereby have an indirect impact on the entire ecosystem.
The impact of gaseous emissions
During the operation of the VHP transfer window, vaporized hydrogen peroxide will exist in gaseous form inside the transfer window. After disinfection is completed, it will be discharged into the surrounding environment through the ventilation system. The emission of high-concentration hydrogen peroxide gas into the air may have a certain impact on air quality, irritate the human respiratory tract and eyes, and cause harm to human health.
In addition, hydrogen peroxide may participate in some chemical reactions in the atmosphere. Although it eventually decomposes into harmless water and oxygen, under certain specific conditions, it may interact with other pollutants, causing secondary pollution.
Equipment wear and tear and waste generation
Long-term use of VHP transfer Windows can lead to wear and tear on the equipment itself. Components of the transfer window, such as seals, pipes, and spray devices, may need to be replaced regularly. If these discarded equipment parts are not handled properly, they will become solid waste and put pressure on the environment.
Meanwhile, during the operation of the transfer window, some condensate water and cleaning wastewater may be produced. This wastewater may contain residual hydrogen peroxide and other impurities. If discharged directly without treatment, they may cause pollution to the water environment.
