Die vorliegende Erfindung betrifft ein System und ein Verfahren zur Behandlung von Wasser, insbesondere Trinkwasser, zur Entfernung von Verunreinigungen, insbesondere Legionellen mit einer Vorrichtung zur Zugabe eines Mittels zur Unschädlichmachung der Verunreinigungen und einem Filtersystem das einen Vorfilter und einen Feinfilter umfasst.The present invention relates to a system and a method for the treatment of water, in particular drinking water, for the removal of contaminants, in particular Legionella with a device for adding a means for neutralizing the impurities and a filter system comprising a pre-filter and a fine filter.
Trinkwasser aus öffentlichen und nicht öffentlichen Netzen kann, obwohl es den mikrobiologischen Bestimmungen der Trinkwasserverordnungen entspricht, trotzdem geringe Konzentrationen von Keimen aufweisen, beispielsweise Legionellen. Letztere können bei anfälligen Personen die sogenannte Legionärskrankheit, eine schwere Lungenentzündung, auslösen. Legionellen vermehren sich bei Temperaturen des Wassers zwischen 30 und 50°C, das heißt Wassertemperaturen wie sie bei Trinkwassernetzen im Wohnungsbau, öffentlichen Gebäuden, sowie Schwimmbädern auftritt.Drinking water from public and non-public networks, although it complies with the microbiological provisions of the drinking water regulations, may still have low concentrations of germs, such as Legionella. The latter can cause the so-called legionnaires' disease, a severe pneumonia, in susceptible persons. Legionellae multiply at temperatures of water between 30 and 50 ° C, that is, water temperatures that occur in drinking water networks in housing construction, public buildings, and swimming pools.
Im Stand der Technik ist bekannt, in Systemen zur Bereitstellung von erwärmtem Trinkwasser Legionellenvermehrung durch Aufheizen über 65°C zu vermeiden. Dies erfordert jedoch ein regelmäßiges Aufheizen des gesamten Systems, was energieaufwändig und mit Verbrühungsgefahr verbunden ist. Auch wird hierdurch die Gefahr von Verkalkung und Korrosion erhöht.It is known in the art to avoid legionella proliferation by heating above 65 ° C in systems for providing heated drinking water. However, this requires a regular heating of the entire system, which is energy-intensive and associated with scalding. This also increases the risk of calcification and corrosion.
Desweiteren sind chemische und elektrolytische Behandlungsverfahren bekannt, so kann zur Vorbeugung von Legionellenbefall kontinuierlich Desinfektionsmittel in das Leitungsnetz eingebracht werden. Ein derartiges System wird beispielsweise in

Beim Abtöten von biologischen Verunreinigungen, insbesondere Legionellen mittels Einleitung von Desinfektionsmittel bleiben jedoch Verunreinigungen in Form von abgestorbenen Mikroorganismen im Wasser erhalten. Diese können unter Umständen nach Verbrauch des Desinfektionsmittels das Wachstum von weiteren Mikroorganismen als Nährboden beschleunigen, und werden daher typischerweise aus dem Wasser entfernt, beispielsweise durch Filter. Die bekannten Filtersysteme sind jedoch nicht optimal bezüglich der Filterleistung. Bei den typischen Porengrößen der eingesetzten Filter von über 50 μm ist nicht gewährleistet, dass die Verunreinigungen ausreichend aus dem Wasser entfernt werden. Der Einsatz von Feinfiltern mit niedrigeren Porengrößen führt jedoch regelmäßig zu einem Zusetzen des Filters.When killing biological contaminants, in particular Legionella by means of introduction of disinfectant, however, impurities in the form of dead microorganisms remain in the water. These may possibly accelerate the growth of other microorganisms as a nutrient medium after consumption of the disinfectant, and are therefore typically removed from the water, for example by filters. However, the known filter systems are not optimal in terms of filter performance. With the typical pore sizes of the filter used of more than 50 microns, it is not guaranteed that the impurities are sufficiently removed from the water. However, the use of fine filters with lower pore sizes regularly leads to clogging of the filter.
Erfindungsgemäß wurde nun überraschenderweise gefunden, dass durch Einsatz eines Filtersystems, das ein Vorfilter sowie ein Feinfilter umfasst, wobei letzteres regelmäßig gespült wird, eine ausgezeichnete Reinigung des Wassers von Verunreinigungen, insbesondere mikrobiologischen Belastungen erreicht werden kann, und trotzdem ein kontinuierlicher Betrieb der Anlage möglich ist.According to the invention it has now surprisingly been found that by using a filter system comprising a pre-filter and a fine filter, the latter is rinsed regularly, an excellent cleaning of the water by impurities, in particular microbiological stresses can be achieved, and still a continuous operation of the system is possible ,
Die Erfindung betrifft daher ein System zur Behandlung von Wasser, insbesondere Trinkwasser, zur Entfernung von Verunreinigungen, insbesondere Legionellen, gemäß Schutzanspruch 1.The invention therefore relates to a system for the treatment of water, in particular drinking water, for the removal of impurities, in particular Legionella, according to
Das erfindungsgemäße System ist zur Durchführung eines Verfahrens zur Behandlung von Wasser, insbesondere Trinkwasser, zur Entfernung von Verunreinigungen, insbesondere Legionellen geeignet. Die Erfindung betrifft daher auch ein Verfahren zur Behandlung von Wasser, insbesondere Trinkwasser, zur Entfernung von Verunreinigungen, insbesondere Legionellen, umfassend die Schritte der Zugabe von Mitteln zur Unschädlichmachung der Verunreinigungen, und Leiten des Wassers durch ein Filtersystem, wobei das Filtersystem ein Vorfilter sowie ein Feinfilter umfasst, wobei das Feinfilter eine Porengröße unter 1 μm aufweist und regelmäßig gespült wird. Typische Zeitintervalle der regelmäßigen Spülung sind im Bereich von 30 Sekunden bis 12 Stunden, vorzugsweise jede Minute bis jede 60 Minuten, insbesondere alle 30 Minuten. Die Spüldauer liegt typischerweise bei 5–60 Sekunden. Gespült wird typischerweise mit dem Filtrat des Vorfilters, oder mit Frischwasser.The system according to the invention is suitable for carrying out a process for the treatment of water, in particular drinking water, for the removal of impurities, in particular Legionella. The invention therefore also relates to a Process for the treatment of water, in particular drinking water, for the removal of impurities, in particular Legionella, comprising the steps of adding agents for neutralizing the impurities, and passing the water through a filter system, the filter system comprising a pre-filter and a fine filter, wherein the fine filter has a pore size below 1 micron and is rinsed regularly. Typical time intervals of the regular rinse are in the range of 30 seconds to 12 hours, preferably every minute to every 60 minutes, especially every 30 minutes. The purging time is typically 5-60 seconds. Rinsing is typically done with the filtrate of the prefilter, or with fresh water.
Durch das hohe Redox-Potential des Desinfektionsmittels von mindestens 950 mV erfolgt neben der Unschädlichmachung von Legionellen auch eine Desinfektion bzw. Zerstörung von Amöben, zudem ist ein Abbau des vorhandenen Biofilms im Rohrleitungsnetz gegeben. Dies ist gleichzeitig der Nährboden für Amöben und Mikroorganismen. Erfindungsgemäß hält das System keine Mikroorganismen im Zulauf zurück, sondern trennt abgestorbene Biomasse bzw. Mikroorganismen aus dem Zirkulationsrücklauf des Gebäudes ab, damit diese nicht aus der Installation erneut in den Warmwasserspeicher sowie das Rohrnetz eindringen können. (Sofortmaßnahme zur direkten Gefahrenabwehr. Beseitigt nicht die Ursachen bzw. Mängel in der Bestandsinstallation) Due to the high redox potential of the disinfectant of at least 950 mV, in addition to the harmlessness of Legionella also a disinfection or destruction of amoebae, also there is a degradation of the existing biofilm in the pipeline network. This is also the breeding ground for amoebae and microorganisms. According to the invention, the system does not retain microorganisms in the feed, but separates dead biomass or microorganisms from the circulation return of the building, so that they can not re-enter the hot water tank and the pipe network from the installation. (Immediate action for immediate danger prevention, does not eliminate the causes or deficiencies in the existing installation)
Das Filtersystem umfasst ein Vorfilter, das typischerweise eine Porengröße über 10 μm aufweist, vorzugsweise 50–200 μm, insbesondere 70–100 μm, beispielsweise etwa 90 μm. Das Feinfilter des Filtersystems hat eine Porengröße von unter 1 μm, vorzugsweise von 0,02–0,05 μm, insbesondere 0,02–0,2 μm. Geeignete Vorfilter sowie Feinfilter sind im Stand der Technik bekannt und kommerziell erhältlich z. B. von LEGIO-Water GmbH, Walddorfhäslach, Deutschland (z. B. Serie LFFx oder LBFx); PB International, Zelhem, Niederlande; oder Donaldson Filtration Deutschland GmbH, Haan.The filter system comprises a pre-filter, which typically has a pore size of more than 10 μm, preferably 50-200 μm, in particular 70-100 μm, for example about 90 μm. The fine filter of the filter system has a pore size of less than 1 .mu.m, preferably from 0.02 to 0.05 .mu.m, in particular 0.02 to 0.2 microns. Suitable prefilter and fine filters are known in the art and commercially available for. From LEGIO-Water GmbH, Walddorfhäslach, Germany (eg LFFx or LBFx series); PB International, Zelhem, The Netherlands; or Donaldson Filtration Germany GmbH, Haan.
