In addition to cleanroom guidelines and strict cleanroom contamination control, the cleanroom disinfection procedures are still required to reduce the overall bioburden in the facility continuously. That is to say, only by strictly disinfecting the air in the clean workshop of the enterprise can the microbial content in the air be effectively controlled, and the cleanliness of the clean workshop can reach a new height.
Especially in the production of pharmaceuticals, medical equipment, cosmetics, or food, it is a requirement to clean and disinfect facilities. At present, there are many methods of disinfection in cleanrooms, mainly UV disinfection, air filtration, ozone, and fumigation disinfection, electrostatic adsorption, etc.
It is necessary to choose one or two methods to control the microbial content in the cleanroom. Youthtech has been a professional cleanroom supply manufacturer in China since 2005. In this post, we will share with you three methods of cleanroom disinfection.
Ozone disinfection method
It is the most popular method of cleanroom disinfection. Ozone disinfection has the advantages of a long disinfection effect and no residue and no dead ends. It can effectively kill microorganisms in the air. Ozone sterilization is greatly affected by the impact of temperature, humidity, and concentration.
Generally, ozone sterilization is better in an environment with low temperatures and high humidity. The disinfection time should be according to the size of the cleanroom and the cleanliness requirements. Although ozone disinfection has its advantages, it is difficult to remove microorganisms on the surface of objects effectively. Ozone has the advantages of high efficiency, environmental protection, and low economic cost, but it also stimulates the human body.
Electrostatic adsorption disinfection method
Electrostatic adsorption uses a high concentration of cations to adsorb negatively charged bacteria in the air, but the particle diameter size is closely related to the removal effect. The electrostatic adsorption method is not harmful to the human body. It is perfect for the production process of the clean workshop of the food company. It overcomes the disadvantages of ultraviolet disinfection, fumigation, and ozone disinfection. Still, this sterilization method is also not suitable for food cleaning workshops with high temperatures and high humidity.
Aerosol spray disinfection
The cleanroom disinfection technology mainly uses aerosol sprays to disinfect the air and the surface of the workshop items. Common disinfectants include peracetic acid, quaternary ammonium salts, or hydrogen peroxide. This kind of disinfection method is also the disinfection of chemical substances with strong toxicity and irritation, and chemical substances will remain in the food. Therefore it is not suitable for food workshops.
As we know, cleanroom maintenance is very important for product processing, so cleanroom disinfection is critical in cleanroom maintenance. In Youthtech, our products include cleanroom air filters, purification equipment, cleanroom furniture, clean room panels.
