What is a swimming pool UV sterilizer?


Swimming pool UV disinfection equipment is widely used in swimming pools, hydrotherapy pools, small spa facilities and Olympic standard swimming pools, etc. Swimming pool ultraviolet disinfection can reduce the dosage of chlorine, reduce residual chlorine, and reduce trihalomethanes , Kill Legionella in swimming pools and shower pools, kill microorganisms, permanently inactivate chlorine-resistant microbial organizations, etc. 1. The principle of ultraviolet disinfection of swimming pools According to the differences in their biological functions, ultraviolet rays can be divided into UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm) and vacuum ultraviolet rays.

In water treatment, the UV-C part of ultraviolet rays is actually used, in this band 260nm Nearby has been proven to be the most efficient ultraviolet light for sterilization. The ultraviolet sterilizer adopts a specially designed high-efficiency, high-intensity and long-life ultraviolet UV-C light generating device to irradiate the flowing water with strong ultraviolet UV-C light. When bacteria, viruses, etc. in the water are irradiated by a certain dose of ultraviolet UV-C light (wavelength 253.7nm).

Its cell DNA and structure are destroyed, and cell regeneration cannot proceed, so as to achieve water disinfection and purification. The spectral line with a wavelength of 185nm can also decompose organic molecules in water, generate hydrogen radicals and oxidize organic molecules in water to carbon dioxide, so as to achieve the purpose of removing TOC. 2. General regulations for disinfection of water supply and drainage of swimming pools and water recreation pools by ultraviolet irradiation 1. Ultraviolet lights with a wavelength of 254NM should be used; 2. The amount of ultraviolet radiation should meet the sterilization requirements of the actual circulating water volume of swimming pools; 3. The ultraviolet disinfection device should have Measures to prevent quartz glass fragments from entering the swimming pool; 4. The multi-lamp ultraviolet disinfection device should be equipped with an alarm signal for individual lamp failures; 5. The ultraviolet disinfection should be supplemented by chlorine disinfection.

3. The application of ultraviolet disinfection in swimming pool equipment The advantages of ultraviolet disinfection in swimming pools: 1. Reduce residual chlorine The chlorine content in swimming pool water is reduced, which reduces disinfection by-products and makes the swimming pool environment healthier. 2. Reduce the dosage of chlorine When chlorine reacts with organic compounds on swimmers, disinfection by-products, such as chloramines, are produced. These by-products are the source of discomfort to people's eyes and respiratory organs.

Chloramines are corrosive and can attack pool walls and pipes. UV lamps can reduce chlorine usage to within required limits by exposing the full recirculation water stream to UV radiation. 3. Reduce trihalomethanes In pool water that is disinfected with chlorine, one of the disinfection by-products is trihalomethanes (THMs).

The most common is chloroform, which is a suspected carcinogen. UV irradiation, combined with reduced chlorine dosage, reduces the chloroform content in the pool water. 4. Another advantage of using ultraviolet technology to purify pool water is that it can permanently inactivate chlorine-resistant microorganisms, such as Legionella pneumophila, Escherichia coli, Pseudomonas, Cryptosporidium, amoeba and bacteria .

UV rays inactivate these microorganisms by damaging their DNA and DNA repair enzymes. 5. Kill Legionella in swimming pools and showers Legionella is an extremely dangerous pathogenic microorganism that appears in swimming pools and warm water circulation showers. It is resistant to residual chlorine, but is killed by UV light.

Temperature does not affect the action of the UV light, making it ideal for warm baths. Fourth, the characteristics of ultraviolet sterilizer disinfection equipment 1. The ultraviolet sterilizer uses high-efficiency UV-C (LL or LH) ultraviolet lamps, and selects the world's leading low-voltage high-intensity ultraviolet lamps. The service life of the lamps is guaranteed to be more than 8000-10000 hours . 2. The ultraviolet sterilizer uses a high-transmittance, high-purity quartz sleeve to ensure that the ultraviolet rays pass through more than 90%.

3. The ultraviolet sterilizer adopts the world's advanced constant and high-intensity ultraviolet special ballast, which can ensure the normal operation of the whole system under complex conditions. 4. The ultraviolet sterilizer uses high-quality sanitary stainless steel as the reactor, and the inner wall of the reactor is specially polished to improve the sterilization effect Poolking is the best swimming pool equipment manufacturer and supplier in China.
