Abstract
This article explores the efficiency of using the ETRO-02 ozonator, powered by solar energy, in the water purification process. The objective of the study is to find an environmentally friendly and economically efficient method for eliminating microorganisms in water by powering the ozonator with alternative energy sources. The research materials included water sourced from the Kapshagay reservoir, as well as solar panels and the ozonator device. During the study, solar panels with the capacity to produce 4.2 to 5.5 kWh of energy daily were used, which was sufficient to ensure the continuous operation of the ozonator. The total bacterial contamination in the water decreased from 12,000 CFU/ml to 45 CFU/ml, and coliform bacteria were reduced from 25 CFU/100 ml to 1 CFU/100 ml. Additionally, dangerous microorganisms such as Enterococcus, Salmonella, and Legionella were completely eliminated. The efficiency of the ozonator in removing bacteria and viruses was between 90-99%. In conclusion, the solar-powered ozonator proved to be an environmentally friendly and economically viable solution for effective water purification, particularly suitable for remote and rural areas.
