Information about UV-C ultraviolet radiation:

In the effect of short-wave radiation on a living organism, the greatest interest is in the effect of ultraviolet rays on biopolymers - proteins and nucleic acids. Biopolymer molecules contain ring groups of molecules containing carbon and nitrogen, which intensively absorb radiation with a wavelength of 260...280 nm. The absorbed energy can migrate along the chain of atoms within the molecule without significant loss until it reaches weak bonds between atoms and destroys the bond. During this process, called photolysis, molecular fragments are formed that have a strong effect on the body. For example, histamine is formed from the amino acid histidine - a substance that expands blood capillaries and increases their permeability. In addition to photolysis, denaturation occurs in biopolymers under the influence of ultraviolet rays. When irradiated with light of a certain wavelength, the electric charge of molecules decreases, they stick together and lose their activity - enzymatic, hormonal, antigenic, etc.
The processes of photolysis and protein denaturation occur in parallel and independently of each other. They are caused by different ranges of radiation: rays of 280...302 nm cause mainly photolysis, and 250...265 nm - mainly denaturation. The combination of these processes determines the picture of the effect of ultraviolet rays on the cell.
The most sensitive cell function to the action of ultraviolet rays is division. Irradiation at a dose of 10 (-19) J / m2 causes the cessation of division of about 90% of bacterial cells. But the growth and vital activity of cells does not stop. Over time, their division is restored. To cause the death of 90% of cells, suppression of the synthesis of nucleic acids and proteins, the formation of mutations, it is necessary to bring the radiation dose to 10 (-18) J / m2. Ultraviolet rays cause changes in nucleic acids that affect the growth, division, heredity of cells, i.e. the main manifestations of life.
The importance of the mechanism of action on nucleic acid is explained by the fact that each DNA (deoxyribonucleic acid) molecule is unique. DNA is the hereditary memory of the cell. Its structure contains encrypted information about the structure and properties of all cellular proteins. If any protein is present in a living cell in the form of tens and hundreds of identical molecules, then DNA stores information about the structure of the cell as a whole, about the nature and direction of metabolic processes in it. Therefore, violations in the structure of DNA can be irreparable or lead to serious disruption of life.

Ultraviolet lamps are used to sterilize (disinfect) water, air and various surfaces in all areas of human life. Complete sterilization from microorganisms using UV radiation is impossible - it does not affect some bacteria, many types of fungi and prions.

In the most common low-pressure lamps, almost the entire spectrum of radiation falls at a wavelength of 253.7 nm, which is in good agreement with the peak of the bactericidal efficiency curve (i.e. the efficiency of ultraviolet absorption by DNA molecules). This peak is located in the region of a radiation wavelength of 265 nm [13], which has the greatest effect on DNA, but natural substances (e.g. water) delay the penetration of UV.

Relative spectral bactericidal efficiency of ultraviolet radiation is the relative dependence of the action of bactericidal ultraviolet radiation on the wavelength in the spectral range of 205-315 nm. At a wavelength of 265 nm, the maximum value of spectral bactericidal efficiency is equal to one.

Bactericidal UV radiation at these wavelengths causes dimerization of thymine in DNA molecules. The accumulation of such changes in the DNA of microorganisms leads to a slowdown in the rate of their reproduction and death. Ultraviolet lamps with a bactericidal effect are mainly used in such devices as bactericidal irradiators and bactericidal recirculators.

Ultraviolet treatment of water, air and surfaces does not have a prolonged effect. The advantage of this feature is that it eliminates harmful effects on humans and animals. In the case of wastewater treatment with UV, the flora of water bodies does not suffer from discharges, as, for example, when water treated with chlorine is discharged, which continues to destroy life long after use at treatment facilities.

Ultraviolet lamps with a bactericidal effect are often simply called bactericidal lamps in everyday life. Quartz lamps also have a bactericidal effect, but their name is not due to the effect of action, as in bactericidal lamps, but is associated with the material of the lamp bulb - quartz glass.

Disinfection of water is carried out by chlorination in combination, as a rule, with ozonation or disinfection with ultraviolet (UV) radiation. Disinfection with ultraviolet (UV) radiation is a safe, economical and effective method of disinfection. Neither ozonation nor ultraviolet

UV radiation does not have a bactericidal aftereffect, so they are not allowed to be used as independent means of water disinfection when preparing water for domestic and drinking water supply, for swimming pools. Ozonation and ultraviolet disinfection are used as additional methods of disinfection, together with chlorination, they increase the efficiency of chlorination and reduce the amount of added chlorine-containing reagents.

The principle of action of UV radiation. UV disinfection is carried out by irradiating microorganisms in water with UV radiation of a certain intensity (the wavelength sufficient for the complete destruction of microorganisms is 260.5 nm) for a certain period of time. As a result of such irradiation, microorganisms "microbiologically" die, since they lose the ability to reproduce. UV radiation in the wavelength range of about 254 nm penetrates well through water and the cell wall of the water-borne microorganism and is absorbed by the DNA of microorganisms, causing a violation of its structure. As a result, the process of reproduction of microorganisms stops. This mechanism applies to living cells of any organism as a whole, which is what causes the danger of hard ultraviolet radiation.

Although UV treatment is several times inferior to ozonation in terms of water disinfection efficiency, today the use of UV radiation is one of the most effective and safe methods of water disinfection in cases where the volume of treated water is small.

Currently, in developing countries, in regions experiencing a shortage of clean drinking water, the method of water disinfection with sunlight (SODIS) is being introduced, in which the ultraviolet component of solar radiation plays the main role in cleaning water from microorganisms.
