Introduction. Disinfection of sweat water is one of the main factors of the epidemiological well-being of the population. The classic and most common method of water purification is the use of chemicals. But this method has a whole effect on chemicals, in particular, on chemicals that can cause health problems, in particular, when chlorine compounds are used as a negative disinfecting agent. In addition, during military operations or man-made disasters, there is a need for individual means of water disinfection. This method, an alternative to the classical method, is the use of ultraviolet radiation for water disinfection. Today, during infectious industrial disinfection at city water treatment plants, UV radiation is used in combination with chemical and other physical methods of disinfection of drinking water. But today, low-pressure UV lamps work there, which additionally creates a large amount of ozone. For individual use, even in conditions where the power supply is limited or absent, this is unacceptable. Therefore, in the context of compactness and energy saving, it is effective to use LED lamps, which have an undeniable advantage over old UV lamps, especially low-pressure mercury lamps. In our review of the features of the work of LEDs, in particular, the bactericidal effect at different wavelengths, the time of their effective use. At the same time, one of the main factors affecting the use of UV LEDs is the possibility of creating monochrome sources of ultraviolet radiation and very low energy consumption, which allows you to create a compact device specifically for individual use. Thus, it is possible to obtain a program that will be effective for disinfecting sweat water without the use of chemicals or boiling.
The aim of the study is to analyze literature data and determine ways to improve the method of using UV radiation for drinking water disinfection.
Materials and methods. Analytical review of scientific publications was carried out using scientometric databases SCOPUS, Web of Science, Index Copernicus International Google Scholar CrossRef and others, periodicals and publications.
Results and their discussion. The advantages and disadvantages of the main methods of drinking water purification are considered and summarized, depending on their effectiveness, convenience, and the presence of side effects for human health. Modern ultraviolet LEDs have been found to be a promising alternative for water disinfection due to many advantages over traditional means and methods. Their use opens up the possibilities of using various wavelengths, opening angles and innovative designs. The unique characteristics of UV LEDs, including multiple wavelengths and pulsed illumination, can increase disinfection efficiency not only under optimal conditions, but also when used in the field, during combat operations, or in emergency situations where the normal water supply is disrupted..
Conclusions. Today, in the conditions of the Russian war against Ukraine, there is an urgent need to develop a portable device for disinfecting drinking water in the field, during hostilities, or in emergency situations (natural disasters, man-made accidents and disasters, etc.), to provide military personnel or civilians population with drinking water without the risk of infectious diseases transmitted by the fecal-oral route.
A promising direction of water disinfection may be the development of methods and devices using portable energy-saving sources of UV radiation based on LED technologies.
Keywords: ultraviolet radiation, drinking water disinfection, microorganisms, UV lamps, UV LED monochrome source.
