The advantages of using ultraviolet light to kill aquatic infectious pathogens have been widely recognized. In fact, industry was one of the early adopters of this technology. Today, almost all industries apply UV technology to water treatment systems.
Ultraviolet disinfection is the main application of ultraviolet technology in the field of water and wastewater. 1. Sterilization: The ultraviolet sterilizer mainly uses ultraviolet light with a wavelength of 254 nanometers. Ultraviolet light of this wavelength, even under a small amount of ultraviolet projection dose, can destroy the life core of a cell - DNA, thus preventing cell regeneration, losing the ability to regenerate and making bacteria harmless, thereby achieving the effect of sterilization.
2. Eliminate ozone: The ultraviolet sterilizer mainly uses ultraviolet light with a wavelength of 254 nanometers. Ultraviolet light of this wavelength, even under a small amount of ultraviolet projection dose, can destroy the life core of a cell - DNA, thus preventing cell regeneration, losing the ability to regenerate and making bacteria harmless, thereby achieving the effect of sterilization. 3. Reduce the amount of total organic carbon: In many high-tech and laboratory installations, organic matter will hinder the production of high-purity water.
There are many ways to remove organic matter from water, the more common methods include the use of activated carbon and reverse osmosis. UV rays with shorter wavelengths have more energy and are therefore able to break down organic matter. 4. Liquid sugar disinfection: Since sugar is a food that is easily utilized by bacteria, it is easy to promote bacterial reproduction.
Plus, liquid sugar is opaque, so it's hard to sterilize thoroughly. To compensate for the energy loss caused by the viscosity and color of the liquid, many UV emitters need to be packed tightly together to form a so-called "thin-film" reactor. 5. Degradation of residual chlorine: In municipal water treatment and water supply systems, chlorine disinfection is very necessary.
However, in the industrial production process, in order to avoid adverse effects on the product, the removal of residual chlorine in water is often a necessary pre-treatment. The basic methods for eliminating residual chlorine are activated carbon bed and chemical treatment. The disadvantage of activated carbon treatment is that it needs to be constantly regenerated, and it often suffers from bacterial growth problems.
6. Surface and air disinfection: The use of ultraviolet sterilizers for air disinfection has a long history as the use of ultraviolet rays for water disinfection. Air disinfection equipment has been used in hospitals, clinics and decontamination rooms for many years. The principle of air disinfection is the same as that of water disinfection.
Typically, UV lamps can be installed in the air duct, in front of the coil, or mounted on a shelf fixed to the wall. When the air passes by, the microorganisms in the air are killed and rendered harmless. 7. Cooling tower disinfection: In order to reduce the cost of biocides and the health hazards of chemical treatment, the ultraviolet system can be installed in the water circulation system of the cooling tower to play a role in sterilization.
When used in conjunction with filters, UV light can effectively control microbial growth in cooling towers. Although a certain concentration of biocide still needs to be retained in the cooling tower, the application of a UV sterilizer can greatly reduce its usage.
