How Ozone is Used for Sterilization of Domestic Water

Ozone, whose chemical formula is O₃, is also called three atom oxygen. It is named for its fishy smell. It can be reduced to oxygen at room temperature. The specific gravity of ozone is larger than that of oxygen, and it is easy to dissolve in water and decompose. Because ozone is composed of one oxygen atom carried by oxygen molecule, which determines that it is only in a temporary storage state. In addition to oxidation, the remaining oxygen atoms carried are combined into a stable state, so ozone will not cause secondary pollution to the environment. 

Disinfection Principle of Ozone

Ozone is a kind of strong oxidant. Its molecule is very unstable, and it can decompose and produce monoatomic oxygen (O) and hydroxyl (OH) with strong oxidation ability. It is a unique bacterium melting preparation, which can quickly integrate into the cell wall, destroy the internal structure of bacteria, viruses and other microorganisms, and has a strong killing effect on various pathogenic microorganisms. The sterilization process is a kind of biochemical oxidation reaction. It is because ozone has a good disinfection effect, so it is also used to disinfect domestic water. At present, most water plants still use the traditional disinfection method, that is, using disinfectants containing chlorine elements to disinfect the domestic water, but the disinfection effect is not as good as ozone. In order to make domestic water cleaner, we can buy an ozone water purifier or ozone water filter.

The disinfection effect of ozone is mainly reflected in the following ways. Ozone can oxidize and decompose the enzymes needed for glucose in bacteria, which makes bacteria dead. Ozone can act on genetic substances in bacterial cells, such as purine and pyrimidine in nucleic acids, destroy their organelles, DNA and RNA, destroy the metabolism of bacteria, and cause bacterial death. Ozone can react with the lipid double chain of the bacterial cell wall, penetrate the cell membrane, invade the cell, act on the lipoproteins of the outer membrane and lipopolysaccharides of the inner membrane, make the bacteria have permeability distortion and dissolve to death. Ozone can act on the four polypeptide chains of the capsid protein of the virus, and damage the RNA to form its protein.

Advantages of Ozone Disinfection

Ozone is a high quality disinfectant, which has the characteristics of high sterilization efficiency and peculiar smell removal. Because ozone is a kind of gas, it can enter some cracks to kill the microbes in the cracks. When ozone is used to disinfect domestic water, it can quickly dissolve in water and kill microorganisms in water. Ozone can kill a variety of microorganisms, such as bacteria, spores, viruses, fungi, protozoa and Rickettsia. In addition to disinfection, ozone can also remove the peculiar smell in water. Ozone can be produced by an ozone generator. In the process of disinfection, the excess oxygen atom in ozone will change into oxygen 30 minutes later, so using ozone to disinfect will not cause secondary pollution to the environment. There is no residual substance in ozone disinfection, which solves the problem of cleaning disinfectant after disinfection.
