Biocide
What is biocide (Microbicide)
Biocide (microbicide) in the paper industry plays an important role in our society and provides us with various types of paper products. However, the industry faces a significant challenge in preventing the growth of microorganisms on paper surfaces. To solve this problem, biocide agents are usually used in the paper industry.
Biocidal agents are chemicals used to kill or inhibit the growth of microorganisms such as bacteria, fungi, and
Algae are designed.
In this article, different types of biocide agents (microbicide) used in the paper industry, their performance and their impact on the environment and
We will check human health.
types of Biocide
One of the common biocide agents in the paper industry is chlorine. Chlorine compounds such as chlorine dioxide and hypochlorites are effective in controlling microbial growth on paper surfaces. These biocide agents act by disrupting the cell wall and membrane of microorganisms, which leads to their destruction. Chlorine-based biocides are popular due to their broad-spectrum antimicrobial properties, affordability, and availability.
Another important biocide agent used in the paper industry is quaternary ammonium compounds (QACs).
These compounds contain nitrogen atoms with a positive charge that can bind to the cell membrane of microorganisms with a negative charge.
and cause cell lysis and death.
QACs are preferred due to their low toxicity and stability, but against certain types of microorganisms compared to
Chlorine-based biocides are less effective.
In addition to chlorine and QACs, other biocide agents used in the paper industry include organic acids such as sorbic acid and
Benzoic and inorganic biocides are like silver nanoparticles.
Organic acids act by disrupting metabolic processes in microorganisms, while silver nanoparticles
They release silver, which is toxic to a wide range of microorganisms.
Function
The primary function of biocide (microbicide) agents in the paper industry is to prevent microbial growth that can lead to paper color change, odor,
Physical damage and release of toxic compounds.
Microbial growth on paper surfaces can occur at various stages of the paper production process, including storage, transportation, and use.
Biocide (microbicide) agents are added to paper or applied as a coating to inhibit microbial growth and maintain the quality and beauty of paper products.
Environmental concerns
Despite their advantages, the use of biocide agents in the paper industry raises environmental concerns.
These chemicals can have negative effects on aquatic ecosystems when they contain paper waste
Biocides are discharged into water bodies.
Biocide agents can accumulate in the environment and harm fish, amphibians and other aquatic organisms.
In addition, the release of biocide-resistant microorganisms in the environment may lead to the emergence of resistant strains.
become an antibiotic, which is a threat to human health.
To reduce these environmental concerns, it is necessary to adopt sustainable practices for the paper industry. This includes the use of alternative and less toxic biocidal agents such as natural antimicrobial compounds derived from plants or microbes. In addition, the implementation of effective wastewater treatment processes can help to remove or reduce the concentration of this material agents before discharging the water into the environment.
Result
As a result, biocidal agents play an important role in the paper industry by preventing microbial growth on paper surfaces. The use of this material agents such as chlorine, quaternary ammonium compounds and organic acids helps to maintain the quality and integrity of paper products.
However, their use raises environmental concerns about their impact on aquatic ecosystems and the potential emergence of antibiotic-resistant microorganisms.
Therefore, the paper industry should prioritize finding sustainable alternatives and implementing appropriate wastewater treatment to minimize the negative environmental and health effects associated with the use of biocide agents.
