摘要： The invention relates to the purification of untreated water which is polluted with dissolved organic carbon compounds which can be biologically or adsorptively removed in a three-step process, whereby the upstream purification step is predominantly biological, i.e. operates as a biofilter (1), and both subsequent purification steps are predominantly adsorptive in nature, i.e. operate as adsorbers (2, 3). The biofilter (1) is purified by backwashing, whereby the backwashing periods occur according to the TOC determined between the biofilter (1) and the upstream adsorber (2) and/or running time and/or pressure loss. The upstream adsorber (2) is also cleaned by backwashing and is subsequently shifted into a downstream position alternating with the other adsorber (3). The method is suitable for obtaining TOC concentrations in treated water of less than 500 ppb.

摘要： Verfahren zur Entkeimung und zur Eliminierung von Biofilmen und/oder Bioschleimen in Kühlkreisläufen mit Rückkühlwerken, indem in den Kühlkreislauf folgende Vollmetallkatalysatoren eingebracht werden, an denen als Betriebsmittel impulsweise zuzudosierende wässrige Peroxoverbindungen aktiviert werden und die Zudosierung erst dann erfolgt, wenn im zu behandelnden System die Anzahl der im Wasser frei beweglichen Keime eine vorgebbare Mindestkonzentration erreicht bzw. überschritten hat.
