Industrial High-Concentration Ozone Generation System
1. Product Overview
ClearFlow Water-Cooled Ozone Generators are designed for industrial water treatment, wastewater treatment, disinfection, and oxidation applications that require a reliable and continuous supply of high-concentration ozone.
Using oxygen-fed ceramic plate corona discharge technology, these industrial ozone generators convert oxygen into ozone through a high-efficiency electrical discharge process. The system delivers an ozone concentration of 140–300 mg/L and offers ozone output capacities ranging from 50 g/h to 5 kg/h, with larger capacities available upon request.
Designed for 24/7 continuous operation, the water-cooled ozone generator features a double-electrode water-cooling structure that helps maintain stable operating temperatures and supports long-term performance. Its modular discharge cells, integrated protection system, and stainless steel cabinet make operation and maintenance more convenient.
The system supports PLC-based automatic control or manual operation, providing flexible control options for different industrial applications.
For improved ozone utilization, ClearFlow water-cooled ozone generators can be integrated with gas-liquid mixing pumps and ozone nanobubble generators to enhance ozone dissolution and mass transfer in water.
Whether used in municipal wastewater treatment, industrial effluent treatment, aquaculture, swimming pools, or process water disinfection, ClearFlow provides ozone generation solutions tailored to different treatment capacities and operating requirements.
2. How Does a Water-Cooled Ozone Generator Work?
A water-cooled ozone generator produces ozone through the corona discharge process, using oxygen as the feed gas.
Its working process generally includes the following steps:
Step 1: Oxygen Supply
An external oxygen source supplies oxygen to the ozone generator. The oxygen purity should be at least 90%, with a supply pressure of 0.06–0.3 MPa.
Step 2: Corona Discharge
Oxygen passes through ceramic plate corona discharge cells. Under the action of a high-voltage electric field, oxygen molecules (O₂) are converted into ozone molecules (O₃).
Step 3: Water Cooling
During ozone generation, electrical discharge produces heat. The double-electrode water-cooling structure circulates cooling water through the relevant cooling components to help control operating temperatures.
Step 4: Ozone Output
The generated high-concentration ozone gas is delivered to the downstream treatment system through an ozone-resistant gas pipeline.
Step 5: Ozone Mixing and Treatment
Ozone can be introduced into water through a gas-liquid mixing pump, an ozone injector, or a nanobubble generation system. It then participates in oxidation, disinfection, and other water treatment processes.
The overall treatment performance depends on ozone dosage, water quality, contact time, mixing efficiency, and the characteristics of the target contaminants.
