Ocena skuteczności filtracji wody i jakości wód popłucznych w instalacjach basenowych

The building and operating costs of sports and recreation facilities, especially those of the swimming pools, are very high. That is why designers and investors make a lot of effort to reduce them. The optimization of water management in swimming pools tends towards increasing the filtration efficiency, reducing the amount of water needed, decreasing the frequency of water replacement in the swimming pools and considering the possibility of reusing the effluents from the filtration systems. The paper presents the profiles of three swimming pools and a detailed discussion of the results obtained, which makes it possible to assess the efficiency of filtration and the extent of pollution in the effluents from the filtration system. The effluents were analyzed for particular pollutants, especially nitrogen compounds and chloramines, to find out whether or not they can be discharged directly into rivers or reused for the watering of greens and commons.
