What are the advantages of ozone generator in swimming pool water treatment?

Since SCHOEMBEIM discovered ozone in 1840, the application of ozone has a history of more than one hundred years. Below and Qingdao Aikang ozone generator manufacturer Xiaobian together to look at its history of development. Ozone has been widely used in swimming pool water treatment and disinfection systems as a strong oxidizing agent and an efficient broad-spectrum fungicide alongside fluorine. With the improvement of people's awareness of environmental protection and health, the improvement of production technology and the reduction of production costs, the use of ozone disinfection swimming pools has gradually replaced chlorine disinfection swimming pools, and has been accepted by people. Currently, all public swimming pools in Europe and North America use ozone disinfection. There are more than 500,000 swimming pools in the United States that are widely used in Europe. In 1997, Hong Kong converted all public swimming pools to ozone disinfection. In China, since the 1990 Asian Games, many large public swimming pools, water parks, swimming pools and SPA fitness and leisure clubs have adopted ozone disinfection. Ozone-sterilized swimming pools are going from the aristocracy to the masses.

■ The strongest fungicide.

Ozone is a very active and highly oxidizing oxidizing agent. Ozone is one of the most commonly used oxidants in nature. It mainly depends on its strong oxidation and bactericidal effect. Ozone and its secondary products (such as hydroxyl) have the strongest bactericidal activity and virus inactivation. Ozone is a very powerful, broad-spectrum fungicide. It oxidizes and breaks down the bacteria's glucose oxidase and dehydrogenase enzymes. It can also interact directly with bacteria, thereby disrupting the REDOX process of bacterial material metabolism, thus disrupting bacterial growth and reproduction, and causing bacterial death. Its bactericidal effect is rapid, usually within a few seconds can effectively kill bacteria, viruses, spores and eggs in the water, can effectively prevent the spread of infectious diseases. Experiments have shown that the same concentration of ozone kills bacteria and viruses 600-3000 times more efficiently than chlorine. At an ozone concentration of 1 mg/l, Enterococcus faecalis took only 5 seconds to inactivate, while the same concentration of chlorine took 15,000 seconds to achieve the same effect. Rapid killing of chlorine-resistant spores and F phages is particularly important. Viruses such as ADIS and red-eye virus, which is powerless against chlorine, can be completely killed.

■ Environmental protection and green fungicide.

Ozone is an internationally recognized environmental protection green fungicide. The ozone disinfection process of circulating water in swimming pool is a complete oxidation process. The only product is dissolved oxygen, which does not increase the harmful substances and salt content of the water, nor does it cause any secondary pollution to the environment. In order to disinfect the traditional chlorine disinfection method in the swimming pool, it is necessary to add a large number of chlorine-containing disinfectants, chlorine preparations will react with the organic matter in the water to form various chlorinated organic compounds, such as trichloromethane, chloroform and so on. These substances are generally considered carcinogenic mutagens.

■ Improved health and comfort.

The swimming pool is chlorinated. Over time, the chlorinated organic compounds and chlorine gases that evaporate from the water gather in the pool and are not easily dispersed, damaging the human respiratory organs. People in the pool can smell the pungent chlorine and feel uncomfortable in their chest and lungs. At the same time, these toxic substances are absorbed by the body (in water, the body can absorb 500 per hour). In milliliters of water, the eyes become irritated when swimming and cause congestion and redness; Long-term swimmers will find that the hair becomes yellow and brittle, the skin is rough, etc., which seriously affects people's health. Ozone disinfection in swimming pool water treatment eliminates the formation of chlorinated ammonia compounds and can fundamentally avoid the production of carcinogenic halogenated organic compounds such as trihalomethanes (THMS). It is these chloramines that irritate the skin, eyes and airways of swimmers and athletes. Red eyes and skin diseases can occur during swimming. They also have a bleaching effect on hair. Using ozone-sterilized swimming pools does not cause such problems, and the swimmers are very comfortable. During the treatment process, the residual ozone in the water returned to the swimming pool will not exceed the safe limit. It can also disinfect and purify the air, making the indoor air fresh and comfortable.

■ Degradation and removal of contaminants from water.

According to the data of the Beijing Municipal Health and Epidemic Prevention Station, the content of organic matter, especially ammonia nitrogen (urea), in chlorinated swimming pools exceeds the standard for several times, and the water is easy to deteriorate.

■ Greatly reduce pharmaceutical consumption.

When using chlorine disinfection, due to the addition of chlorine preparations, it will inevitably lead to a change in the pH value of the water, making people feel uncomfortable, so it is necessary to add a large number of alkaline or acidic agents to neutralize. High temperature and large passenger flow, water quality is often poor, at this time, chlorine preparations need to be added in large quantities, and ozone is a neutral substance, will not produce such problems. Ozone can ensure the stability of water quality during high passenger flow and high temperature season. However, because the half-life of ozone is very short and can not be retained in water for a long time, it is still necessary to add a small amount of chlorine-containing fungicides as an auxiliary long-acting disinfectant, but the amount of chlorine can be reduced by more than 65%. At the same time, ozone has a micro-flocculation effect, so under normal passenger flow, flocculants can be used. Under certain conditions of use, such as counter-current circulation, without the use of activated carbon filter tanks, and even without adding chlorine preparations, flocculants, and pH regulators, ozone can be used as the only agent for water treatment.

■ Reduce corrosion of facilities.

The hypochlorous acid and its derivatives produced by chlorination have seriously corroded the equipment and structures in the swimming pool, such as the grid and heating system. After the use of ozone disinfection, the amount of chlorine disinfectant is greatly reduced.

■ Better water quality.

The ozone disinfection system is also equipped with activated carbon adsorption filter to remove the residual ozone and organic pollutants in the circulating water of the pool, which not only ensures the safety of the ozone disinfection system but also deeply treats the circulating water, and its water quality will be better than ordinary tap water.

■ More convenient and safe to use.

Ozone production raw materials are inexhaustible, inexhaustible oxygen in the air, therefore, in the production process do not have to consider the problem of handling or storage, ozone generator operation and use is very simple, with high safety, daily management and maintenance work is also relatively simple. However, chlorine preparations have certain risks in transportation, storage and use.

Characteristics of ozone use in the swimming pool industry:

■ Fast response, small dosage: ozone can quickly kill bacteria, spores, viruses spread in the water and have a bactericidal inactivation effect at very low concentrations.

■ Strong adaptability: In the range of PH 5.6-9.8 and water temperature 0-37 ℃, it has little impact on the disinfection performance of ozone.

■ Ozone half-life is very short, 20 minutes can be decomposed into oxygen, no secondary pollution in water,

■ Can destroy organic matter in water, improve the physical properties of water and organ feeling, decolorization and odor removal, so that the water is azure blue, without changing the nature of water
