  • Unknown about swimming pools and analysis of pool water

During the summer months, we swim, train, train, learn how to swim in what condition, how to clean or whether the pool managers take the necessary precautions come to mind many questions. As users, we can control this situation; How can we be sure of the cleanliness of the swimming pools?

Pool cleaning should be done periodically. It is very easy to get sick in the pools which do not have regular maintenance and cleaning. By cleaning the pool in certain periods, you will not encounter more permanent problems in the pool and you will have health and hygiene that relaxes your pool pleasure. Pool water analysis is of great importance in this sense. We need to examine whether the analysis is performed in the swimming pool we use.

According to the Regulation on the Amendment of the Regulation on Health Principles and Conditions to be Subject to Swimming Pools; In particular, hotel pool forwarders have to periodically analyze and analyze pool water. The analysis and limit values ​​of the analyzes that they have to do and have to do are as follows:

(1) It is used in pools where chlorinated compounds with stabilizers are used for disinfection of water.

(2) If hydrogen peroxide + biguanide is used for disinfection of water, hydrogen peroxide should be in the range of 40-80. In this case, pH 8.2, ammonium 1.5 and total alkalinity up to 220 are considered appropriate. Free chlorine measurement is not done in these pools, hydrogen peroxide and biguanide are measured.

(3) Chlorine and chlorinated compounds are used in disinfection of water.

(4) Ozone, UV, chlorine dioxide and other disinfection systems are used for disinfection of water.

NOTE: Hydrogen peroxide, biguanide and free chlorine measurements are made at the pool location.
