To mitigate microbial activity in swimming pools and to assure hygienic safety for bathers, pool systems have a re-circulating water system ensuring continuous water treatment and disinfection by chlorination. A major drawback associated with the use of chlorine as disinfectant is its potential to react with organic matter (OM) present in pool water to form potentially harmful disinfection by-products (DBP). In this thesis, the treatment performance of different combinations of conventional and novel treatment processes was compared using a pilot scale swimming pool model that was operated under reproducible and fully controlled conditions. The quality of the pool water was determined in means of volatile DBPs and the concentration and composition of dissolved organic carbon (DOC). Further, overall apparent reaction rates for the removal of monochloramine (MCA), a DBP found in pool water, in granular activated carbon (GAC) beds were determined using a fixed-bed reactor system operated under conditions typical for swimming pool water treatment. The reaction rates as well as the type of reaction products formed were correlated with physico-chemical properties of the tested GACs.

Wasser ist für Kinder ein faszinierendes Medium. Es eröffnet vielfältige Bewegungsmöglichkeiten und bietet im Sommer erfrischende Abkühlung. So erfreuen sich Baden und Schwimmen auch in sächsischen Einrichtungen der Kindertagesbetreuung (Kita) großer Beliebtheit. Einige Einrichtungen betreiben eigene Badebecken, andere nutzen öffentliche Bäder. Leider ereignen sich im Zusammenhang mit dem Badevergnügen immer wieder folgenschwere Unfälle, die schlimmstenfalls tödlich enden können. Kinder ertrinken lautlos. Vor allem für Nichtschwimmer oder für unsichere Schwimmer können sich erhebliche Gefahren ergeben. Damit das Baden und Schwimmen in der Kita für Kinder zu einem sicheren Erlebnis wird, hat die Unfallkasse Sachsen wichtige Hinweise für Kita-Leitungen und die verantwortlichen pädagogischen Fachkräfte zusammengefasst.
