This research focuses on studying the process of wastewater treatment using electrical discharge. The introduction highlights the harmful effects of ammonia, nitrites, phosphates, and heavy metals found in wastewater and their impact on water pollution. The purpose of the study is to investigate and evaluate the efficiency of decomposing harmful substances in water using ozone and hydroxyl radicals generated by high-and low-frequency electrical discharges. During the experiment, a voltage of 15 kV and an ozone concentration of 600 g/h were applied. The results showed that the initial ammonia concentration decreased from 130 mg/L to 1 mg/L, while nitrites were reduced from 0.5 mg/L to 0 mg/L. In addition, phosphates (from 30 mg/L to 0 mg/L), chlorides (from 250 mg/L to 20 mg/L), and sulfates (from 200 mg/L to 18 mg/L) significantly decreased. The COD level dropped by 70%, from 800 mg/L to 0 mg/L, and the bacterial count decreased by 85% within 30 minutes, reaching 100% elimination by 60 minutes. The energy consumption was 0.5 kWh per liter of water, proving this method to be an efficient and environmentally friendly solution. The conclusion highlights the potential of the electrical discharge method for water purification without chemical additives, its environmental safety, and its applicability on an industrial scale.
