Abstract
As a result of the research the following methods have been proposed for controlling harmful microorganisms: sterilization of water by laser radiation at wavelengths of 425 nm, 355 nm and 308 nm. The results of theoretical and experimental studies on the development and establishment of a system of ultraviolet disinfection of water for injection (UFOVI) intended for research sterilized water for injections. The pipe created a strong turbulent water flow. Performance irradiation laminar flow of 1.5 liters per second. Irradiation was carried out at three wavelengths 425 nm, 355 nm and 308 nm with energies semiconductor laser diode arrays to 4 MJ / cm3. Wavelength tuning implemented current in the range of 10 nm. For large capacities, we have developed a miniature solid state laser, which was used in fluid microorganisms inactivator. In the water treatment process breaks up to 98% of microbes, but can be left among pathogenic viruses destruction which requires special handling.
