This scientific work is focused on detoxifying and purifying harmful compounds in the groundwater of the Talgar district, Almaty region, using a pilot autonomous complex unit. The groundwater in the district contains heavy metals, chemical compounds, and microorganisms that pose a threat to human health and the environment. During the research, comprehensive purification methods for water detoxification and purification were considered. A pilot ETRO-02 ozonator unit, based on a special electrical corona discharge, was developed for the purification system. Filtration methods and UV radiation were also applied. The research results aim to improve the quality of groundwater and make it suitable for use in autonomous drinking water systems. During the experimental work, the efficiency of the water purification unit, its parameters, and their impact on water quality were determined. This research is an important step towards providing clean and safe drinking water in rural and urban areas. Comprehensive studies were conducted to determine the effects of ozone dose, contact time of the treated water with the ozone-air mixture, water temperature, concentration of pollutants, filtration rate, iron, manganese, and the degree of water disinfection according to the sanitary rules and regulations (2.1.4.1074-01). The ozone dose ranged between 1.5 mg/l, the contact time with the ozone-air mixture between 5 to 20 minutes, the water temperature between 9 to 15ºC, and the filtration rate between 8 to 15 m/hour. As a result, the concentration of iron significantly decreased with increasing oxidation time, from an initial value of approximately 1.4 mg/l to about 0.1 mg/l within 20 minutes. The concentration of manganese also decreased, albeit at a slower rate, from an initial value of 0.2 mg/l to about 0.03 mg/l within 20 minutes. This demonstrated that heavy metals could be effectively removed from water over a prolonged period using ozone. Additionally, the initial water contained 17 general microbial count and a coliform index of 1575, which were completely eliminated after passing through the purification unit, meeting the sanitary standards (SanPiN 2.1.4.1074-01). Moreover, data from the experiments were processed using SMath Solver and Python, and an algorithmic code was written.
