[Hongjie Water] In water treatment, UV sterilizer PK ozone generator

For other sterilization and disinfection methods, ultraviolet sterilizers and ozone generators have been more widely used in the water treatment industry in recent years. Ultraviolet rays can destroy bacterial DNA, while ozone can have a strong oxidizing effect. Depending on the environment, the two have their own unique bactericidal and disinfection effects.

The sterilization principle of ultraviolet sterilizers in water treatment:

Research has shown that ultraviolet rays with wavelengths between 200-290mm can penetrate the cell membrane of bacteria or viruses, causing damage to nucleic acids (DNA) that control genetic phenomena and biological functions, rendering them incapable of branching and reproducing, thus achieving the goal of sterilization.

Experiments have shown that ultraviolet radiation with wavelengths between 250-260mm is more easily absorbed by nucleic acids (DNA) than other wavelengths. That's why this wavelength of ultraviolet radiation has the strongest bactericidal ability. Perform bacterial treatment according to the required amount of ultraviolet radiation to kill the microorganisms, without causing any changes in water quality. Perform flash sterilization in a very short period of time with good results. Moreover, this treatment is completed within a straight tube flow type device.

Analysis of advantages in UV sterilizer water treatment:

1. Broad spectrum, ultraviolet sterilization has the highest broad-spectrum ability, and it can efficiently kill almost all bacteria and viruses;

2. Efficient sterilization, the use of ultraviolet radiation to kill bacteria and viruses generally achieves a sterilization rate of 99% -99.9% within one to two seconds;

3. Low operating and maintenance costs, small footprint of UV sterilization equipment, and simple structural requirements result in lower total investment. In terms of operation, the cost is also relatively low;

4. Safe and reliable operation, traditional disinfection techniques such as using chlorides or ozone, whose disinfectants themselves are highly toxic and flammable substances. The ultraviolet disinfection system does not have such safety hazards;

5. No secondary pollution, UV sterilization does not add any chemical agents, so it will not cause secondary pollution to the water body and surrounding environment. Do not alter any components in the water.

The application principle of ozone generator in water treatment:

Friends with some knowledge of chemistry must know that ozone belongs to the category of strong oxidants. Like chlorine, ozone can play a role in both disinfection and oxidation. In addition, ozone has stronger disinfection and oxidation ability than chlorine, which can oxidize organic matter in water and kill viruses, spores, and bacteria. Ozone is produced on-site using air or pure oxygen through an ozone generator, with yields of 1% -3% and 2% -6%, respectively.

Analysis of advantages of ozone sterilization:

1. Ozone disinfection can reduce the concentration of total organic halides in water.

2. Ozone can reduce the generation of halogenated alkane disinfection by-products such as THMs in water.

3. Ozone disinfection has a rapid reaction, high sterilization efficiency, and can effectively remove residual organic matter, color, smell, taste, etc. in water, with little influence from pH value and temperature.

Summary:

The above briefly introduces the roles of ultraviolet sterilizers and ozone generators in water treatment. It is not difficult to see that both sterilization and disinfection methods have their own advantages. Of course, they are also limited by some limiting factors, such as poor water quality and high turbidity, which severely restrict the efficiency of ultraviolet sterilization. Ozone disinfection can produce substances such as aldehydes, ketones, and alcohols. If chlorinated, it can produce harmful substances such as trihalomethanes.

In summary, UV sterilizers and ozone generators have their own advantages in the field of water treatment. Reasonable selection based on specific environment can achieve perfect sterilization and disinfection goals. With the rapid development of industrial economy, global water resources are showing varying degrees of pollution. In recent years, with the rapid development of the domestic economy, the situation of water resource pollution in China is not optimistic. I believe that in this context, the water treatment industry in China and even the world will continue to develop rapidly and vigorously in the coming years.
