CHLORINE DISTRIBUTION IN THE INDOOR AND OUTDOOR SWIMMING POOLS

The results of research on the distribution of chlorine content in the characteristic points of the outdoor pool (SPO) and indoor pool (SPI) are presented. Sports and recreational pools for swimmers were selected for the study. Technical and technological parameters of these pools are presented. Free chlorine and combined chlorine were the basic parameters affecting the quality of pool water. Their quick and easy estimation allowed to assess the spread of the disinfectant in swimming pools and the effectiveness of its operation. In both swimming pools, there was a large variation in the chlorine content and non-compliance with the requirements in this area (in SPI, content of combined chlorine > 0.3 mg Cl₂/dm³, in the SPO content of free chlorine > 0.6 mg Cl₂/dm³). In the SPI, in contrast to the SPO, a significant variation in chlorine concentrations was observed in samples taken from various points in the same series. Based on the analysis of the chlorine content in the characteristic points of swimming pools and physio-chemical and bacteriological supplementary parameters, an attempt was made to determine reliable sampling points to assess the quality of water. The test results were compared with the recommendations regarding the quality of swimming pool water.
