Короткий опис (реферат):
Solar disinfection (SODIS) is a
simple and affordable way to disinfect drinking water. WHO has recommended SODIS as a
domestic water treatment (HWT) technology. Theoretical and methodical foundations of solar
disinfection of drinking water are presented in previous domestic publications. Approbation and
hygienic evaluation of this method has not been carried out in Ukraine so far. Goal. Hygienic
evaluation of the effectiveness of solar disinfection of drinking water. Research methods. Sanitary
and hygienic, sanitary and microbiological, statistical. Research results. The total duration of
experiments in all cases was the same - 6 hours. The air temperature was 35-38 °C, bottled water
38-41 °C, the maximum dose of solar radiation (mVt/cm2) 76-82, the first inoculation of coliforms
(CFU/100ml) 105. It was established that in all 4 experiments during July 2024, solar disinfection
of drinking water provided 5 log10 inactivation of total coliforms. The results correspond to the
literature data on the high efficiency of solar disinfection of drinking water. The need for careful
adherence to certain established methodical procedures is emphasized, which will create
conditions for effective inactivation of microorganisms and epidemic safety of drinking water, as
well as development and research of alternative materials or modification of existing ones to
increase their availability. Conclusion. The obtained results are preliminary, but they should be
considered as the first step in research on the optimization and expansion of the spectrum of
application of solar disinfection of drinking water.
