UV lamp disinfection – For swimming pools
Ultraviolet pool lamps are probably the most common pool disinfection equipment. This article discusses the principle of operation, effectiveness, and cost of UV lamps for pools. Over the past year, pool disinfection without the use of chlorine and expensive reagents has become more and more popular, and this includes UV lamps. The high dollar rate makes UV pool lights not just effective, but extremely profitable.
Every season hundreds and thousands of pool users (both private and commercial) face force majeure (unforeseeable) situations, such as water blooms, overdose of chemicals, bacterial contamination, etc. All this is unpleasant, but also very dangerous for the health of the swimmers.
Special equipment for pool disinfection with ultraviolet radiation can be used, which will disinfect the water almost without expensive chemicals.
UV pool lamps are probably the most common pool disinfection equipment. UV sterilizers have gained popularity due to their ease of use, low cost, and obvious benefits such as high disinfection rates and reduced consumption of pool chemicals. Pool UV lamps produce strong electromagnetic radiation, the spectral composition, which depends on the manufacturer and the lamp model and varies in range from 250-260 nm.

UV rays, reaching the surface of microorganisms and viruses, penetrate and destroy their DNA, as well as permanently suspend the metabolism of germ cells. With UV energy some organic compounds are broken down, including chloramines - products of chlorine oxidation of organic substances. It is chloramines that, when the concentration increases, cause a pungent smell of chlorine and unpleasant sensations for swimmers, such as burning eyes, skin and mucous membrane itching.
The ultraviolet pool unit almost completely breaks down the chloramines, and the products evaporate as simple compounds. However, while the intensity of radiation must be about 30 mJ/m² for bactericidal action, twice the lamp efficiency is required to break down chloramines.
That said, there are still conflicting opinions in the scientific world as to whether certain strains of viruses and microorganisms have developed resistance and immunity to chlorine and bromine. Many pool UV lamp manufacturers follow this line of thinking and claim that their UV lamps will "back up" the chlorine. We agree that it is the chlorine "to back up" UV lamps and classic water chlorination with calcium or sodium hypochlorite remains effective and necessary for cleaning and disinfection of swimming pools.
A wisely chosen UV lamp reduces the usage of pool chemicals by a significant rate because of the decrease in the number of organic substances, bacteria and microorganisms in the water.
UV light is harmful to humans, but it does not go beyond the sterilizer chamber.
