Description
Anschwemmplattenfilter für die Trinkwasseraufbereitung, Die Erfindung betrifft ein Anschwemmplattenfilter für die Trinkwasseraufbereitung, das aus wenigstens zwei pordsen Platten aus Kunststoff oder keramischem Material besteht, die zwischen sich Abflußkanäle für das Reinfiltrat bilden. Alluvial plate filters for drinking water treatment, the invention relates to a precoat filter for drinking water treatment, which consists of at least two pordsen plates made of plastic or ceramic material, which between drainage channels for the pure filtrate are formed.
Als Anschwemmaterial dienen Kieselgur, Aktivkohle, faserige oder andere feinkörnige, anschwenunbare Filterhilfsmittel.Diatomaceous earth, activated carbon, fibrous or other can serve as the precoat material fine-grained, swellable filter aids.
Die völlige Reinigung von Wasser, insbesondere von Trinkwasser, wird hierdurch erreicht, allerdings muß sich, um ein einwandfreies, entkeimtes Trinkwasser zu erhalten, noch eine Behandlung, die in den meisten Fällen mit Chemikalien durchgeführt wird, anschließen.The complete purification of water, especially drinking water, will This is achieved, however, in order to have flawless, sterilized drinking water to get another treatment, which in most cases is done with chemicals will connect.
Aufgabe der Erfindung ist es, das eingangs beschriebene Filter so zu verbessern, daß es neben einer ultrafeinen Filtrierwirkung auch eine vollständige Entkeimung des Wassers einschließt.The object of the invention is to provide the filter described above to improve that there is not only an ultrafine filtering effect but also a complete one Includes disinfection of the water.
Eine Lösung wurde darin gefunden, daß auf oder in den dem Anschwemmaterial zugewandten Flächen der porösen Platten eine zusammenhängende oder etwas durchbrochene, festanhaftende Schicht aus Silber-, Kupfer- oder Silberkupfer-Legierung oder einem ähnlichen, eine oligodynamische Wirkung aufweisendes Material gebildet ist.A solution has been found in that on or in the precoat material facing surfaces of the porous plates a coherent or somewhat openwork, firmly adhering layer made of silver, copper or silver-copper alloy or a similar material exhibiting an oligodynamic effect is formed.
Das Anbringen des Materials kann durch aufsprühen in Pulverform, durch Zumischung vor dem Sintern der Platten oder dergleichen erfolgen. Hierdurch wird in einem Arbeitsgang das gesamte, durch die darüberliegende angeschwemmte Filterschicht klar filtrierte Wasser von der oligodynamisch wirkenden Schicht erfasst und der Entkeimung unterworfen.The material can be applied by spraying it on in powder form Mixing takes place before sintering the plates or the like. This will the entire filter layer washed up on top of it in one operation Clearly filtered water captured by the oligodynamically acting layer and the Subjected to sterilization.
Das Filter eignet sich vor allem für dn Katastropheneinsatz, da es schnelie " einfach und komplikationsfrei arbeitet und somit auch praktisch nur für die Trinkwasseraufbereitung dienlich ist.The filter is particularly suitable for use in disasters, as it schnelie "works simply and without complications and thus practically only for the drinking water treatment is useful.
Wenn man das Wasser lediglich an eingetauchten Körpern aus oligodynamischem Material vorbeifließen lässt, können niemals sämtliche Bereiche erfasst werden und die etwaige Zumischung von derartigem Material in pulverisierter Form zu der Anschwemmaese wäre zu kostspielig, da für die Entkeimung ungereinigten Wassers große Mengen feinkörnigen Silbers benötigt wurden, das nach jedem Rückspülvorgang verloren ginge.If you just put the water on immersed bodies from oligodynamic Lets material flow by, all areas can never be captured and the possible admixture of such material in powdered form to the precoat would be too expensive, as large quantities of fine-grained water are used to disinfect unpurified water Silver were needed, which would be lost after each backwash process.
Es kommen die vorhandenen Mengen z.B. des feinkörnigen Silbers, das in die porösen Filterplatten eingesintert oder aufgesprüht ist, mit mechanisch vollgereinigtem Wasser und damit mit den vereinzelten Bakterien in Verbindung.There are the existing amounts of e.g. fine-grained silver, the is sintered or sprayed into the porous filter plates, with mechanically fully cleaned Water and thus in connection with the isolated bacteria.
Eine Erhöhung der entkeimenden Wirkung kann auch dadurch erzielt werden, daß man zusätzlich zwischen den Platten eine Folie aus oligodynamischem Material einschaltet. Es ist hierbei zweckmäßig, die Stärke dieser Folie etwa vierbis zehnfach so groß zu machen wie die Porengröße der Platten. Statt der Folie kann auch ein Drahtgitter aus oligodynamischem Material zwischen die Platten gelegt werden.An increase in the disinfecting effect can also be achieved by that you also have a film made of oligodynamic material between the plates turns on. It is useful here to use about four to ten times the thickness of this film to make it as large as the pore size of the plates. Instead of the foil, a Wire mesh made of oligodynamic material can be placed between the plates.
Auf der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt und zwar zeigen: Fig. 1 einen Querschnitt durch ein aus zwei Platten bestehendes Filter gemäß Erfindung; Fig. 2 das Filter mit einer ergänzenden Anordnung; Fig. 3 einen vergrößerten Teilschnitt durch ein Filter etwas anderer Ausführungsform; Fig. 4 einen Querschnitt durch ein Filter mit eingelegtem Drahtgitter aus oligodynamisch wirkenden Material; Fig. 5 einen Teilschmitt durch die Filterplatte nach Fig. 4 nach der Linie V-V.Exemplary embodiments of the invention are shown in the drawing namely show: FIG. 1 a cross section through one consisting of two plates Filter according to the invention; 2 shows the filter with a supplementary arrangement; Fig. 3 shows an enlarged partial section through a filter of a somewhat different embodiment; 4 shows a cross section through a filter with an inserted wire mesh made of oligodynamic acting material; FIG. 5 shows a partial Schmitt through the filter plate according to FIG. 4 after the line V-V.
Die beiden Filterplatten 1 und 2, die beispielsweise aus porösem Kunststoff bestehen, weisen an ihren sich gegenüber liegenden Seiten rillenförmige Aussparungen 3 auf, wobei die Rillen der einen Platte senkrecht oder geneigt zu denen der anderen liegen. Die Rillen 3 bilden Kanäle für das Reinfiltrat, das in Pfeilrichtung 4 in einer Mittelaussparung 5 der Platten abgezogen werden kann. Auf den Außenseiten der Platten, die dem etwa in Pfeilrichtung 6 eindringenden Trübfiltrat ausgesetzt sind, befinden sich wasserdurchlässige Beläge 7 aus Silber, Kupfer, einer Legierung aus beiden oder einem ähnlichen, eine oligodynamische Wirkung aufweisenden Material. An der umlaufenden Stirnfläche 8 der Platten ist der Bereich, in dem sich die Rillen 3 befinden, auf eine geeignete Weise, z.B. durch Verschweißen geschlossen.The two filter plates 1 and 2, for example made of porous plastic exist, have groove-shaped recesses on their opposite sides 3 on, where the grooves of one plate perpendicular or inclined to those of the others. The grooves 3 form channels for the pure filtrate, the can be pulled off in the direction of arrow 4 in a central recess 5 of the plates. On the outer sides of the plates, the cloudy filtrate penetrating approximately in the direction of arrow 6 are exposed, there are water-permeable coverings 7 made of silver, copper, a Alloy of both or a similar one, exhibiting an oligodynamic effect Material. On the circumferential face 8 of the plates is the area in which the grooves 3 are closed in a suitable manner, e.g. by welding.
Bei Verwendung der erwähnten Platten, die mit den rillenförmigen Aussparungen versehen sind, ist es zweckmäßig, zwischen die beiden Platten einen Ring 3a (Fig.2) aus Metall od.dgl. einzufügen, um eine Verformung der zwischen den Rillen liegenden tasten beim Aufeinanderpressen der beiden Filterscheiben zu vermeiden.When using the plates mentioned, the ones with the groove-shaped recesses are provided, it is advisable to put a ring 3a (Fig.2) between the two plates made of metal or the like. to insert a deformation of those lying between the grooves to avoid touching when pressing the two filter discs together.
Bei dem Ausführungsbeispiel der Fig. 3 befindet sich zwischen den Platten 1 und 2 noch eine gelochte Folie 3b aus dem erwähnten Material zur Erhöhung der angestrebten Wirkung.In the embodiment of FIG. 3 is located between the Plates 1 and 2 also have a perforated film 3b made of the material mentioned to increase the desired effect.
Der Querschnitt der Fig. 4 veranschaulicht ein Filter, bei dem glatte Filterplatten 1 und 2 verwendet sind, #wischen denen ein Drahtgitter 10 aus oligodynamisub wirkendem Material eingeschaltet ist, das gleichzeitig als Distanzmittel zum Aufrechterhalten des Abstandes der beiden Filter platten dient. Auch hierbei bewirkt die Verwendung eines Drahtgitters aus dem genannten Material eine Erhöhung der angestrebten Wirkung.The cross section of FIG. 4 illustrates a filter in which smooth Filter plates 1 and 2 are used, # between which a wire mesh 10 made of oligodynamisub acting material is switched on, which at the same time as a distance means serves to maintain the distance between the two filter plates. Here too the use of a wire mesh made of the material mentioned causes an increase the desired effect.
In Fig. 5 ist ein Teilschnitt dieses Filters dargestellt.In Fig. 5 a partial section of this filter is shown.
