Abstract

Beim Waschen und Entwässern von Wäschestücken fällt am Ende des Waschvorgangs Behandlungsflüssigkeit an, die noch unverbrauchte waschaktive Substanzen enthält. Diese werden bislang, gegebenenfalls nach einer Neutralisation, mit der Behandlungsflüssigkeit in den Abfluss geleitet. Diese bekannte Vorgehensweise wirkt sich ungünstig auf die Wirtschaftlichkeit des Waschvorgangs aus.When washing and dewatering laundry items falls at the end of the washing treatment liquid, which still contains unused detergent substances. These are so far, optionally passed after neutralization, with the treatment liquid in the drain. This known procedure has an unfavorable effect on the economy of the washing process.

Die Erfindung sieht es vor, aus der nach dem Waschvorgang von den Wäschestücken abgetrennten Behandlungsflüssigkeit verbrauchte waschaktive Substanzen zu entfernen. Dies geschieht durch eine Präzisionsfiltration, bei der nur die durch Schmutzaufnahme aus dem Waschvorgang größeren verbrauchten waschaktiven Substanzen aus der Behandlungsflüssigkeit ausgefiltert werden, aber nicht die eine kleinere Partikelgröße aufweisenden unverbrauchten waschaktiven Substanzen. Diese können zusammen mit der Behandlungsflüssigkeit für einen nachfolgenden Waschvorgang wieder verwendet werden.

Figure imgaf001
The invention proposes to remove spent washing-active substances from the treatment liquid separated from the laundry items after the washing process. This is done by a precision filtration, in which only the washed-off substances which are consumed by dirt absorption from the washing process are filtered out of the treatment liquid, but not the unused washing-active substances having a smaller particle size. These can be used together with the treatment liquid for a subsequent washing process.
