What is the Ozone Generator for Water Treatment?

Ozone is composed of three oxygen atoms and is an allotrope of oxygen. Its molecular formula is O3 and its molecular weight is 48. Under normal temperature and pressure, O3 is a light blue gas with a special fishy smell. When it is in appropriate concentration, it has a kind of "fresh" smell. Ozone is unstable at room temperature and can be decomposed into O2 and monoatomic O by itself. Two monooxygen atoms O can be combined into O2. The monooxygen atoms are extremely active and have strong oxidizing and decomposition functions. It can quickly disinfect, sterilize and oxidize organic and inorganic substances.



1. Introduction of Ozone Generators

The ozone generator for water treatment is a device used to produce ozone gas for industrial sewage treatment. Ozone generator has the advantages of strong oxidation, stable effect and no secondary pollution in water treatment.


Ozone is easy to decompose and cannot be stored. It needs to be prepared and used on site (short-term storage under special circumstances can also be realized). Therefore, ozone generators are needed to produce ozone. Ozone generators are widely used in drinking water, modern sewage treatment, industrial oxidation, food processing and preservation, medical synthesis, and space sterilization. The ozone gas produced by the ozone generator can be used directly, or it can participate in the reaction by mixing with a liquid through an ozone water treatment device.



2. The Treatment Process of Ozone Generators in the Sewage Treatment 

Pretreatment is very important for disinfecting sewage by ozone. The effect of ozone disinfection is often affected by insufficient pretreatment. The degree of sewage treatment must be determined through technical and economic comparisons. The best way to disinfect sewage is to use ozone after secondary treatment, which can not only reduce the dosage of ozone used, but also lower equipment investment costs and operating costs.



3. Advantages of Ozone Generators in Water Treatment

1) Ozone is an excellent oxidant, which can kill viruses and spores with strong chlorine resistance.

2) Ozone disinfection is less affected by the pH and temperature of sewage.

3) Ozone can remove the color, smell, taste, phenol and chlorine in sewage, increase dissolved oxygen in water, and improve water quality.

4) Ozone can decompose difficult-to-biodegradable organic matter and tertiary substances, and improve the biodegradability of sewage.

5) Ozone is easy to decompose in water and will not cause secondary pollution due to residue.


Ozone has a very high sterilization efficiency when used for drinking water disinfection, but it often requires a larger dosage of ozone and a longer contact time when used for sewage disinfection. The main reason is that there are high pollutants such as COD, NO2-N, chroma and suspended solids in the sewage. These substances will consume ozone and reduce the sterilization ability of ozone. Only when the sewage undergoes necessary pretreatment before ozone disinfection can ozone disinfection be more economical and effective. The transfer effect of the contact mode of ozone and sewage will also affect the dosage and disinfection effect of ozone.
