People living in intense city life with the acceleration of population growth in the world; Accordingly, he was obliged to live most of his life in small areas. Unfortunately, one of the biggest problems brought about by the increase in the density of society and production is the quality of the breathing air.
Why Air Sterilization Matters?
In the crowded cities, due to the increase in production and consumption, there is a serious decrease in air quality; On the other hand, sterilization of air is more important with epidemic diseases that take our world. According to the researches, viruses and bacteria in micro droplets coming out of the mouth of people with sneezing, coughing and even speeches have been proved to hang in the air for 3 to 4 hours.
While the increasing epidemic diseases spread in the world by people, the most important issue is to perform air sterilization in a healthy way. While businesses are performing surface sterilization for their customers and themselves; In places where there is a lot of human circulation, there may be problems in air sterilization. In line with this need, UV devices increase their share in the market.
As Yeşil Grup Energy, we will be happy to help solve these problems in the enterprises with the environment disinfection device using ultraviolet light.
What is Ultraviolet Ray?
Ultraviolet rays are one of the electromagnetic radiation such as gamma and microwave rays and the main source of these radiation is the sun. Ultraviolet (ultraviolet rays) are very short wavelengths that we cannot see with the naked eye. While the human eye can see wavelengths between 400nm and 700nm; The wavelength of UV rays is between 100nm and 400nm. Ultraviolet rays are divided into 3 different groups according to their wavelengths.
- UVA (long UV, longwave UV, black light; 315-400 nm): UV rays with long wavelength. Uses are generally used in medical phototherapy and some skin diseases, neonatal phototherapy, printing applications, exposure fluorescents, solarium UVA exposure bulbs, denture treatment.
- UVB (mediumUV, mediumwave UV; 280-315 nm): UV rays with medium wavelength. Usage areas are generally used in medical phototherapy and some skin diseases, vitamin D treatment and some printing applications.
- UVC (shortUV, shortwave UV, germicidal UV; 200-280 nm): For disinfection with ultraviolet light, UV-C lights (UV beam with antiseptic feature known as germicidial) are generally used. UV-C light can kill all kinds of microorganisms due to its short wavelength and high energy. The most effective antimicrobial activity of the ultraviolet ray is 250-260 nm (253.7 nm) wavelength. This wavelength is the wavelength most effectively absorbed by DNA.
Advantages of Ultraviolet Systems
Advantages of UV-C light disinfection compared to chemical sterilization;
- Application of UV air disinfection device is simple. Sterilization fixtures can be mounted on the wall.
- Disinfection with UV-C light does not harm the environment. It disinfects without using any chemicals.
- UV disinfection systems are effective on many microorganisms. Disinfection ability is high.
- Generally, disinfection time of UV systems is short. Although it depends on the light intensity and duration, it usually acts around 10 seconds. It does not need large tanks because it operates faster than chemical disinfection.
- It is not permanent on surfaces that use UV rays. For this reason, UV air disinfection device does not cause any damage to the business after use.
- It does not leave any by-products and residues in the environment or surfaces.
- Air sterilization with ultraviolet does not contain substances such as chemical products that will create corrosion.
- Operation of the UV air disinfection system is simple and the cost of maintenance is low.
Usage Ways of UV-C Air Sterilization
- Air Sterilization: UV rays are used to disinfect ambient air. The important thing here is to prevent UV rays from touching people. Effectiveness can be increased by limiting the area to be applied.
Although there are different application types in air sterilization with ultraviolet, if a filter-free system is used, it is necessary to isolate from the applied section from people during the period of operation of the UV disinfection device. In areas where people are present, equipment that does not pose a risk for human health, which does not leak out UV filters, should also be used.
UV lamps can solve the odor problem in the environment by eliminating the bacteria that cause bad odors in the air.
- Water Sterilization: When UV systems are applied in water disinfection, it is a method with very successful results against harmful patagones as well as planktonic algae. Since it is a UV ray, it does not have any permanence in water and it does not cause any harm for human health.
- Surface Sterilization: UV rays can be applied directly to the surfaces for sterilization purposes. UV-C rays are the most effective wavelength for microorganisms. One of the important points to be considered while performing surface sterilization is to take environmental precautions during the sterilization process in a way that UV rays do not harm people. These rays can generally be used in places such as hospitals, food production centers where sterilization is required.
- Instrument and Equipment Sterilization: This method, which is generally used for disinfection of surgical instruments and equipment with ultraviolet rays, can also be used for equipment requiring sterilization in daily life.
Usage Areas of UV-C Air Sterilization
Air disinfection devices;
- Hospital, clinics; It can be used in areas where sterilization is required such as patient waiting rooms, dormitories, intensive care rooms, operating rooms. It can also be used for surface sterilization purposes in surgical equipment and instruments.
- The food industry has a wide range of uses. Among them are red meat, white meat and product production areas. It is also used in cheese production and milk production factories in product production and other departments.
- It is used in packaging areas, conveyor belts and places in factories producing packaging materials.
- It is applied in the production and storage areas of pharmaceutical factories.
- Food Production factories, meat combinations are applied in the storage area.
- It can be used in restaurants, dining halls, canteens where there is a lot of human circulation.
- Indoor Show Areas are used for bad odor and disinfection in the system in places such as Hotel, Shopping Mall, School, University, Office where there is a lot of human circulation and where there is a common ventilation system.
How UV-C Eliminates Light Microorganisms?
UV lamps used for sterilization; The UV rays they emit are absorbed by the DNA of living microorganisms. The UV rays absorbed by the cell form a covalent bond with the Thymine bases inside the cells, resulting in thymine dimers. These dimers form the basis of the cellular damage of ultraviolet rays. These dimers damaged due to ultraviolet rays cause folding in DNA strands and thus the helix structure of DNA is impaired.
This damage makes it difficult for the cell to create its own DNA sequence prior to division, preventing its processing and activation. Mutant cells, which do not have the ability to grow, occur even if the gene sequence is finished. Thymine dimers are seen in genes that have vital function in cells.
Cell activations are limited by these disruptions in thymine dimers. The short wavelength ultraviolet rays (UV-C rays) have a lethal effect on viruses and bacteria, proportional to the energy emitted by the source per unit area and the duration of the organism.
How Long Does UV-C Light Affect?
The germicidal effect of UV radiation in air sterilization systems depends on the duration and effectiveness. As the irradiation time or intensity of the ultraviolet light increases (voltage increase or proximity to the ultraviolet light source), the number of vegetative cells dying increases..
The energy delivered from the ultraviolet light source to the specific area is measured in microwatts (μW). To prevent activation of microorganisms, the required energy is calculated by multiplying the intensity and duration of the Ultraviolet ray (μW. Seconds / cm2). The energy required to prevent activation of the microorganism varies according to the type and structure of the microorganisms..
Does UV-Light Hurt People?
UV light causes erythema in human skin as a result of intensive and prolonged contact and can lead to the onset of skin cancer. Also, direct eye contact with ultraviolet lamps can cause serious damage to the retina. Due to these side effects, UV radiation is only used as a sterilization tool in some special cases. Sealing feature is very important for sterilization fittings used for sterilization in the environment..
Why should I use UV Air Disinfection Device?
Although businesses perform surface sterilization for the health of their employees and customers; They cannot find a solution for microorganisms suspended in the air where there is a lot of human density or circulation. It is now possible to completely remove microorganisms harmful to human health suspended in the air with UV air sterilization devices with ultraviolet sterilization fixtures!
