This work considers the ozonation of surface water as an effective method for treating water to eliminate microorganisms and remove organic pollutants. However, the ozonation process changes the physicochemical properties of water, notably the pH level. Changes in pH can significantly affect the efficiency of water purification and potentially impact the condition of aquatic ecosystems when the treated water is discharged. This paper presents the results of experimental studies evaluating the dynamics of pH changes in various water bodies (distilled, ionized, tap, and river water) during the ozonation process. Special attention is given to the presence of heavy metal salts in water, which can catalyze the decomposition of ozone and intensify changes in pH. The study shows that ozonating surface water can lead to a decrease in pH, which may necessitate subsequent pH adjustments to maintain optimal levels for various uses of the treated water. The work is of practical significance for improving the efficiency of ozone use in industrial and municipal services and for water purification processes.
