Sažetak
Chlorination, the most used method of water disinfection has many drawbacks, such as the presence of chlorine-resistant microorganisms and the formation of potentially toxic disinfection by-products. Therefore, combined disinfection with UV irradiation is increasingly used in pools to improve the quality of swimming pool water. The aim of our study was to continuously monitor the expanded range of indicators (physico-chemical and microbiological) as well as the number of swimmers in detailed maintenance system of indoor pool a pool with combined water disinfection for one-year period (2019-2020). During a 12-month period, the basic parameters were measured once a day and the advanced parameters every two weeks. During the research due to the COVID-19 situation from March to June the pool was not closed but was maintained all the time. In terms of the analyzed microbiological indicators, the quality of the tested pool water samples was not in doubt. Fecal contamination indicators were not detected, as well as Legionella spp., while P. aeruginosa was detected in the pool at two occasions in small number. Concentrations of THMs, and other physico-chemical indicators which are daily measured, were within the permitted limits. The planned research study will enable the introduction of evidence-based practice, and thus the selection of the most appropriate intervention measures and disinfection methods to improve the quality of pool water.
