A swimming pool is an environment that is easily polluted. And the pollution of swimming pools is usually caused by swimmers. Usually, swimming pools adopt chlorinated water to achieve the sterilization purpose. But now, ozone sterilization in swimming pools is gradually becoming the first choice. Here is why ozone is a better option.

Source of Pollutants

In general, the sources of the pollutants in swimming pools can be mainly divided into microorganisms, undissolved pollutants and dissolved pollutants. Microorganisms such as bacteria, fungi and viruses can be carried by every swimmer. Many of them may cause a certain type of disease. The undissolved pollutants can be floating particles such as hair, skin flakes, or colloidal particles such as skin tissues and soap remains. The dissolved pollutants come mainly from body fluids such as urine, sweat and saliva. Urine and sweat contain components such as ammonia, urea and amino acids. These components cause no instant harm to the swimmers. But when they react with chlorine, which is widely used to purify water, chemical reactions between them will form chloramine, which is an amino compound of chlorine.

About Water Chlorination

Some people think that the strange smell they sense in swimming pools is chlorine. But that’s not the truth. You can’t smell chlorine. What they smell is chloramine. Chloramine can cause eye irritation. If the pH value of water is higher than the normal level that the human eye can tolerate, which is between 7.4 and 7.6, it will to some extent cause eye irritation.

It is estimated that in order to maintain the effective sterilization of the water in swimming pools, the chlorine content in the water needs to be maintained between 0.3-0.5 mg/L. If it is lower than 0.3mg/L, an ideal bactericidal effect cannot be achieved. And if it is over 0.5mg/L, the water in swimming pools will be harmful to people. It may possibly cause irritation to people’s eyes, skin and even hair.

Chlorine’s capability to kill bacteria in water is also largely affected by the pH value of the water. Chlorine is most effective in killing bacteria in water with a pH value between 7.4 and 7.6. When it reaches or exceeds 8.0, chlorine’s bacteria killing function will be decreased by about 80%.

In addition, chlorinated water in swimming pools can also cause irritation to our respiratory system. Studies have shown that swimming pool staff, especially lifeguards and coaches, are more likely to experience respiratory irritation and asthma than other groups of people. Swimmers are more likely than other athletes to develop asthma, rhinitis and respiratory allergies. What’s more, studies have also found that swimming in chlorinated swimming pools may affect children’s immune systems. Therefore, the chlorination of water can meet the requirements of desired sterilization standards. However, from health perspective, chlorination of water can be a great threat to human health.

How about Ozone?

For its strong oxidizing property, ozone can be used as a highly effective disinfectant. Today, instead of chlorination, more and more swimming pools have chosen ozone as their primary disinfection method.

Ozone can oxidize both organic and inorganic substances in water. It will completely avoid the emergence of chlorination by-products such as chloramines and trihalomethanes in water. Ozone also breaks down chlorinated by-products that have formed in the chlorination process, and thus reduces swimmers’ red eyes and breathing discomforts.

Ozone disinfects more than 3,000 times faster than chlorine. And for some chlorine-resistant pathogens such as Shiga’s bacillus, Legionella, E-coli, Neisseria gonorrhoeae, Treponema pallidum, ozone can effectively finish the elimination work.

Not only that, in addition to sterilization, ozone also has a micro-flocculation effect on the organic matters in water, which helps to improve the purification efficiency of the water.

Conclusion

Therefore, ozone sterilization can also provide high-quality water for swimming pools compared with water chlorination. And at the same time, ozone treatment can avoid the threat of chlorinated water to human health. In addition, from an economic point of view, the improvement of water quality in swimming pools can reduce the unnecessary water consumption caused by the frequent water replacement before and the heating cost of water in colder days. In the short term, there will be an economic investment in an ozone treatment system, but such investment will effectively reduce its overall operating cost in the long run.
