Baseny to bardzo drogie pod względem eksploatacji obiekty sportowe, dlatego też osoby zarządzające tymi obiektami szukają sposobów na obniżenie kosztów ich użytkowania. Jednym z nich jest zagospodarowanie popłuczyn dotychczas odprowadzanych do kanalizacji sanitarnej. Oceny możliwości zagospodarowania popłuczyn odprowadzanych z filtracyjnych instalacji basenowych dokonano na podstawie dopuszczalnych wartości podstawowych wskaźników zanieczyszczeń w ściekach odprowadzanych do wód i ziemi (pH temperatura, zawiesiny ogólne, ChZT, BZT5, Pog, Nog, chlor wolny). Badania jakości popłuczyn z 26 basenów wykazały, że ich jakość jest zależna od warunków eksploatacji danego obiegu basenowego, m.in. długości cyklu filtracyjnego i rodzaju złoża. Parametrami uniemożliwiającymi bezpośrednie zagospodarowanie popłuczyn były zbyt duża zawartość zawiesin ogólnych (≥ 35 mg/dm3) oraz stężenie chloru wolnego (≥ 0,2 mg Cl2/dm3). Jakość wód nadosadowych powstałych w wyniku sedymentacji popłuczyn wskazuje na ich przydatność do zagospodarowania. Zastosowanie w obiektach basenowych odstojników popłuczyn umożliwiłoby odciążenie systemów kanalizacji i odpływ wód nadosadowych do wód powierzchniowych lub ich wykorzystanie do nawadniania terenów zielonych w sposób bezpieczny dla środowiska.

Swimming pools are very expensive in terms of exploitation sports facilities, therefore managers of these facilities are looking for methods of reducing the costs of their use. One of the proposed method is the managing of washings previously discharged to the sanitary sewage system. The assessment of possibilities of washings reusing from swimming pool filtration system is based on the limits of basic indicators of pollutants in wastewater discharged to water and soil (temperature, pH, TSS, BOD5, COD, TN, TP, free chlorine). The conducted research of washings quality from 26 tested swimming pools have shown that washings quality is dependent on the operating conditions of the circuit pool, including the filter cycle duration and types of filter bed. The parameters which prevents direct management washings were too high content of total suspended solids (≥ 35 mg/dm3) and the concentration of free chlorine (≥ 0.2 mg Cl2/dm3). Quality washings subjected to sedimentation indicates its usefulness for rational management. The application in swimming pools settling tanks allows discharge sewage systems and drainage supernatants to surface waters or using to irrigation green areas in an environmentally safe way.

Swimming pools are very expensive, in terms of operation, sports facilities. Therefore, investors and managers of these facilities are looking for methods of reducing the costs of their use. One of the proposed methods is the managing of washings previously discharged to the sanitary sewage system. The assessment of possibilities for reuse of washings from swimming pool filtration system is based on the limits of basic indicators of pollutants in wastewater discharged to water and soil (temperature, pH, TSS, BOD5, COD, TN, TP, free chlorine). The conducted research of washings quality from 26 tested swimming pools have shown that washings quality is dependent on the operating conditions of the pool circuit, including the filter cycle duration and types of filter bed. A direct discharge to water or soil may be impossible due to excessive amounts of total suspended solids (above 35 mg/dm3) and free chlorine concentration (above 0.2 mg Cl2/dm3). However, the quality of supernatant water of washings subjected to sedimentation in the laboratory shows that the washings are suitable for reuse. The installation of settling tanks in swimming pool facilities could relieve the sewage systems and allow for the discharge of supernatant water to surface waters or for the irrigation of green areas in an environmentally friendly way.

The main purpose of the research is to show the possibility of using washings after applying simple processes and devices. It is being considered whether they may be drained to watercourses, to the ground, used for watering plants, sprinkling tennis courts and playing fields, flushing toilets or recycled into pool systems. The research concept consisted of comparing the results of physico-chemical analysis of washings samples with the limit values for pollutants in wastewater discharged to water and ground. The research was carried out for 20 pool water treatment plants. It has been shown that the concentration of TSS (total suspended solids) and free chlorine in washings are the main parameters preventing their drainage to the natural environment. The processes of sedimentation or sedimentation assisted by coagulation allow to reduce the TSS concentration below the limit value and leaving the washings to stand for up to several hours or subjecting them to a few minutes of aeration decreases the concentration of free chlorine to an acceptable level. The obtained research results allow to assume that the management of washings in all tested swimming pools would be possible after applying a settler or a settling tank with a coagulant chamber and then a chamber for aeration.
