This study examines the use of a voltage inverter to improve the efficiency of an ETRO – 02 ozonator based on electrical corona discharge. The main objective is to enhance the energy efficiency of the ozonator while ensuring effective water disinfection and purification. The relevance of the work is linked to the increasing problem of water pollution and the growing demand for environmentally friendly purification methods. Traditional ozonators consume a lot of energy, limiting their widespread use. This research aims to overcome these limitations by introducing a voltage inverter to stabilize power supply and increase ozone production. The ozonation process enables the effective removal of harmful substances such as bacteria, viruses, and heavy metals. The study involved using an ETRO – 02 ozonator, a multilevel inverter, and standard filters such as activated carbon and zeolite. Research methods included testing ozone production, energy consumption, and disinfection efficiency across different parameters. Corona discharge technology, which has high energy efficiency, was chosen as the basis for ozone production. Parameters such as inverter frequency, input and output voltage, water pH, temperature, and hardness were tested at various levels. The results showed that the ETRO – 02 ozonator’s performance improves by 20-30% with a voltage inverter. At 220 – 240 V, the ozonator produced 45-65 mg/L of ozone, reaching an 80-95% disinfection efficiency. Increasing the output voltage to a range of 2 – 3 kV raised ozone output to 50-70 mg/L, achieving 85 – 97% efficiency. Water temperature, pH, and hardness were found to influence ozone concentration. Increasing the inverter frequency improved efficiency to 92% and supported energy savings. In conclusion, adding a voltage inverter to the ETRO – 02 ozonator optimizes the water purification process, ensuring high ozone production and energy efficiency. This method offers a sustainable, cost-effective solution for water purification.
