What is a water treatment ozone generator


A water treatment ozone generator is a device that generates ozone gas for wastewater treatment.

The ozone generator has the advantages of stable effect, no secondary pollution and strong oxidizing property in water treatment.


An ozone generator is a device that produces ozone gas (O3).


Ozone decomposition is not easy to store, so it should be used on site (in special cases, it can be stored for a short time), so it can be used to place the ozone required by the ozone generator.

Ozone generators are widely used in drinking water, sewage treatment, industrial oxidation, food processing and preservation, drug synthesis, space sterilization and other fields. The ozone gas of the ozone generator can be used directly, it can be mixed, and then reacted by a mixed liquid device .


working principle

The working principle of the ozone generator for water treatment is to use the principle of high voltage discharge to realize the process of converting oxygen into ozone. That is, a high-voltage alternating current is applied to the high-voltage electrode, with an insulator in the middle and a certain gap. Allow dry purified air or oxygen to pass through. When the high-voltage alternating current reaches a certain value, a purple glow discharge is produced, which excites the oxygen molecules or atoms of air or oxygen into ozone. Ozone formation varies with applied supply voltage and current. Ozone is unstable, and has a strong oxidizing ability to generate monoatomic oxygen atoms after decomposition or to generate monoatomic oxygen (O) hydroxyl (OH) after dissolving in water. Ozone first reacts with the lipid double bonds of the cell wall and cell membrane, and enters the cell through the cell wall and cell membrane. It acts on the outer layer of lipoproteins and the inner layer of lipopolysaccharide, changing the permeability of the inner cell membrane, causing the inner membrane to leak out, eventually leading to cell lysis and death.


Precautions for use

1. Ensure that the inlet and outlet pipes of electricity, gas and water are connected correctly, and set a good grounding to improve the safety of use;

2. Install the ozone generator for water treatment in a dry and spacious place away from high-voltage lines, and ensure a certain space around it to facilitate heat dissipation and maintenance;

3. The capacity of the lines used meets the requirements to ensure the elimination of fire hazards;

4. In the process of ozone preparation, avoid open circuit caused by wet electrodes;

5. For the water-cooled ozone generator, the cooling water quality is better to prevent scaling and affect the heat dissipation effect;

6. For air-cooled ozone generators, the cooling air must be free of moisture, corrosiveness, aerosols, impurities, oily or conductive substances and visible dust;

7. Ozone is harmful to human body, and the allowable concentration in the atmosphere stipulated by the state is 0.2mg/m3. Therefore, if any leakage is found during use, it should be stopped and repaired immediately.

Application advantages
1. Ozone is an excellent oxidant, which can kill viruses and spores, and has strong chlorine resistance;
2. Ozone disinfection is less affected by pH and temperature of sewage;
3. Ozone can remove pollutants such as color, odor, odor and phenolic chlorine in sewage, increase dissolved oxygen in water, and improve water quality;
4. Ozone can decompose refractory organic matter and tertiary substances, and improve the biodegradability of sewage;
5. Ozone is easily decomposed in water and will not cause secondary pollution due to residues.


Scope of application
Water treatment ozone generators are widely used in pharmaceutical synthesis, food processing and insurance, industrial oxidation, drinking water, sewage, space disinfection and other fields.
