Abstract
Description
Die Erfindung betrifft ein Verfahren und die Anordnung von Systembauteilen zum Abbau von organischen Belastungen, insbesondere Legionellen oder Keimbelastungen, in geschlossenen Wasserkreisläufen, geschlossenen Trinkwasserkreisläufen oder offenen Wasserkreisläufen auf der Grundlage von Baugruppen oder Systembauteilen zur Viskositätsänderung oder Oberflächenspannungsänderung von Wasser, der Erzeugung eines punktuell starken Unterdruckes und der Bestrahlung des so behandelten Wassers mit UV-Licht.The The invention relates to a method and the arrangement of system components for the reduction of organic loads, in particular Legionella or Germ loads, in closed water circuits, closed drinking water circuits or open water circuits based on assemblies or system components for viscosity change or surface tension change of Water, the generation of a pointwise strong negative pressure and the Irradiation of the treated water with UV light.
Bislang wurden organische Belastungen, insbesondere Belastungen mit Legionellen in geschlossenen Wasserkreisläufen, wie Trinkwasserkreisläufen aber auch in offenen Wasserkreisläufen wie z.B. an Kühltürmen oder Luftwäschern vorrangig durch thermische Ausheizung des gesamten Wassers bis zu den Abnahmestellen auf meist > 60° C oder durch Zugabe chemischer Substanzen wie Biozide reduziert oder abgebaut. Thermische Verfahren erfordern einen hohen Sicherheitsaufwand an den Abnahmestellen, da durch die hohe Temperatur die permanente Gefahr von Verbrühungen bei Personen besteht. Zudem sind die Betriebs- und Unterhaltungskosten sehr hoch. Chemische Verfahren hingegen bewirken keine dauerhaft zufrieden stellenden Erfolge, da aus Sicherheitsgründen für Personen, welche das Wasser nutzen, die Dosierungen der Chemikalien wie beispielsweise Bioziden sehr gering gehalten werden muss um Vergiftungen bei Personen zu verhindern. Andere Verfahren wiederum nutzen gezielt erzeugte Änderungen der physikalischen Kenngrößen des Wassers, wie z.B. die Viskosität oder Oberflächenspannung, in Verbindung mit der Erzeugung eines punktuell starken Unterdruckes zum Abbau der Legionellen und Keimbelastung aus. Dabei wird, wie in und OS DE 101 14 936 A1 sowie OS DE 102 53 102 A1 beschrieben, einerseits im Unterdruckbereich dieser Anlagen organisch lebendes Material, welches einen eigenen inneren Partialdruck aufweist, durch die vorhandene Druckdifferenz mechanisch zerstört und durch den im Wasser natürlich gelösten und vorhandenen Sauerstoff kalt aboxidiert.So far were organic strains, especially strains with Legionella in closed water circuits, like drinking water circuits but also in open water circuits such as e.g. at cooling towers or airwashers primarily by thermal heating of the entire water up to the delivery points to mostly> 60 ° C or through Addition of chemical substances such as biocides reduced or degraded. Thermal processes require a high level of security the points of sale, because of the high temperature the permanent Danger of scalding consists of persons. In addition, the operating and maintenance costs very high. Chemical processes, however, do not cause permanent Satisfactory success because of safety reasons for people who use the water, the dosages of chemicals such as Biocides must be kept very low to poison people to prevent. Other methods, in turn, use deliberately created changes the physical characteristics of the Water, e.g. the viscosity or Surface tension, in connection with the generation of a point strong negative pressure for Degradation of Legionella and germination. It will, as in and OS DE 101 14 936 A1 and OS DE 102 53 102 A1, on the one hand In the low-pressure area of these plants, organically living material, which has its own internal partial pressure, through the existing Pressure difference mechanically destroyed and by the naturally dissolved in the water and existing oxygen cold aboxidiert.
Gleichzeitig werden bei diesen Verfahren durch die Viskositätsänderung (das Wasser wird physikalisch dünner) die Ablagerungen in dem Rohrleitungsnetz und den Armaturen gelöst und im Wasserkreislauf der Behandlungsanlage zugeführt. Nachteilig ist, dass der Prozess des Abbaus und der Zerstörung der Keime, wie beispielsweise Legionellen, sehr langwierig ist da derartige Anlagen im Bereich der Erzeugung des Unterdruckes selten den gesamten durchgeführten Volumenstrom in den notwendigen keimtötenden Unterdruckzustand versetzen und somit mehrere Durchläufe notwendig sind.simultaneously These changes are due to the change in viscosity (the water becomes physical thinner) the deposits in the pipeline network and the fittings dissolved and in the Water cycle fed to the treatment plant. The disadvantage is that the Process of removal and destruction the germs, such as Legionella, is very tedious there such systems in the generation of negative pressure rarely the whole performed Volume flow in the necessary germicidal negative pressure state and thus several passes necessary.
Aufgabe der Erfindung ist es, ein Verfahren und eine konstruktive Anlagenlösung oder eine Anordnung von für das Verfahren notwendigen Systembauteilen gegen Keimbelastungen in Wasserkreisläufen zu finden, welches den Nachteil der langen Behandlungsdauer von Systemen auf Basis der Viskositäts- oder Oberflächenspannungsänderung in Verbindung mit punktueller Erzeugung eines starken Unterdrucks (Kavitation) aufhebt oder die Behandlungsdauer reduziert.task The invention is a process and a constructive plant solution or an arrangement of for the procedure necessary system components against germ loads in water circuits to find the disadvantage of the long treatment period of Systems based on the viscosity or surface tension change in connection with selective generation of a strong negative pressure (Cavitation) or reduces the duration of treatment.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in Reihe, vor oder nach Wasserbehandlungsanlagen auf Basis Viskositäts- oder Oberflächenspannungsänderung und Systemkomponenten oder Bauteilen zur Erzeugung eines starken Unterdrucks mittels einer Venturi- oder Lavalldüse ein Element zur Bestrahlung des durch diese Anlagen geführten Wassers mittels keimtötenden UV-Lichts angeordnet wird. Eine parallele der Venturidüse ind der Anordnung ist ebenfalls möglich.According to the invention Task solved by that in series, before or after water treatment plants based viscosity or surface tension change and system components or components for generating a strong Underpressure by means of a venturi or Lavalldüse an element for irradiation of the guided by these facilities Water by means of germicidal UV light is arranged. A parallel of the Venturi nozzle in the arrangement is also possible.
Dadurch werden Keime wie z.B. Legionellen, welche in der physikalischen Behandlungsstufe nicht oder noch nicht vollständig abgebaut werden konnten, abgetötet.Thereby germs such as e.g. Legionella, which in the physical Treatment stage could not or could not be fully degraded, killed.
Durch dieses Verfahren und die Anordnung von den Systemkomponenten wird sichergestellt, dass einerseits durch die Änderung der Viskosität oder Oberflächenspannung Keimnester und Ablagerungen im Leitungsnetz ausgespült werden, die Keime im Bereich des Unterdrucks durch die Druckdifferenz des Eigendrucks oder inneren Partialdrucks der Keime zum niedrigerem Umgebungsdruck aufreißen oder aufplatzen, also mechanisch zerstört werden, und mit dem vorhandenen, im Wasser gelösten Sauerstoff, aboxidiert und nach diesen Behandlungsstufen noch vorhandene Keime durch UV-C Licht abgetötet werden. Diese toten Keime werden über den Wasserkreislauf der physikalischen Behandlungsstufe wieder zugeführt und mit dem im Wasser gelösten Sauerstoff zu vorrangig CO2 und H2O oxidiert.By this method and the arrangement of the system components ensures that on the one hand flushed by the change in viscosity or surface tension nests and deposits in the network, the germs in the range of negative pressure by the pressure difference of the intrinsic pressure or internal partial pressure of the germs to lower ambient pressure rupture or burst open, so be mechanically destroyed, and with the existing, dissolved in water oxygen, aboxidized and after these treatment levels still existing germs are killed by UV-C light. These dead germs are recycled via the water cycle of the physical treatment stage and oxidized with the dissolved oxygen in the water to primarily CO 2 and H 2 O.
