The paddling pool in front of the pool entrance reduces the number of pathogens

Using the public pool means that Bathers can transfer microorganisms harmful to health into the water. Therefore, employees do their best to minimize the risk of contamination while swimming. The water in the ponds is constantly filtered, which cannot be hidden, is heavily chlorinated, but this is not the only way. That’s exactly The paddling pools filled with water at the entrance to the pool from the bedroom side play an important role in maintaining cleanliness.

Paddling pools are essential to maintaining better water quality in swimming pools and they perform this function perfectly. This was confirmed in an interview with Geekweek website Dr. M. Edyta Łaskawiec from the Silesian University of Technology – should be used, although it doesn’t look good often.

Although they perform an important function, paddling pools are often overlooked. There is a lot of sand, clothing splinters (such as bulging material from socks) or other dirt inside. A person who enters the pool and sees something like this at the entrance immediately takes a larger step so that he does not enter the water. However, this is a fatal mistake.

everybody Shower trays should be designed in strict accordance with the requirements of the chief health inspector. It should be of such an unavoidable size and a depth of 10-15 cm. They are filled with treated pool water, which is completely changed at least once every hour, but may be changed more frequently.

Complete cleansing is required at least once a day. During the exchange of water, it is either discharged into the sewage system or goes into a closed circuit, where it is purified. The water from this paddling pool has nothing to do with the pool water.

In order for the water to do its part, it must contain the right amount of disinfectant. Unfortunately, regulations currently provide this amount of the agent as recommended, without the need to closely monitor its concentration. The only condition is to maintain the concentration of free chlorine at the level of 1-2 mg / l. The World Health Organization, in turn, gives a dose of free chlorine at a level of 0.7-1.5 mg / l.

Scientists conducted research in the swimming pool of the AGH University of Science and Technology in Krakow, and they showed that The number of bacteria decreased significantly after the foot bathbut also point out that strict control of sanitizer is required.

It was also found that the type of disinfectant used was important – in the case of chlorine dioxide, the number of microorganisms was lower both in the water filling the cavity and on flat surfaces than in calcium hypochlorite. The use of chlorine dioxide is reduced due to the need to store it. Sodium hypochlorite is more popular because it is produced using the electrolysis method and can be produced directly at the facility, notes Dr. Chaskwick.

to summarise, Swimming pool pads do their job and should be used. Research confirms that thanks to them, the number of microorganisms that harm our health in the pool is less.
