Abstract

The purifier for drinking water plants is intended to dissolve lime, fat and other usual contaminants and iron- and/or manganese-containing encrustations. It has a package composed of two part-packages, of which one for the normal sediment has a mixture, packed liquid-tightly, of water-soluble, but solid, organic and/or inorganic acids and/or acid salts in powder or granule form and the other for the iron- and manganese-containing encrustations has ascorbic acid, citric acid and/or a disinfecting and/or deodorising active component in solid form which slowly releases peroxide oxygen and contains the active peroxo group in the form of a chemical compound or a stable adduct, and which purifier contains a compound which is not considered to be a foreign substance according to the water supply standards in the drinking water of drinking water supply plants or wells.

Description

Die Erfindung betrifft einen Reiniger gemäß dem Oberbe­ griff des Hauptanspruchs.The invention relates to a cleaner according to the Oberbe gripped the main claim.

Solche Reiniger liegen in zwei verschiedenen Formen vor. Zum einen werden für den normalen Schmutz und die normalen Ablagerungen flüssige Säuren eingesetzt, die in Kanistern angeliefert werden. Entweder wird diesen flüssigen Säuren als Wirkstoff eine eisen- und/oder manganlösende Verbin­ dung kurz vor der Anwendung zugesetzt, oder aber es wird diese Verbindung zeitlich danach zum Reinigen der Trink­ wasseranlagen eingesetzt.Such cleaners come in two different forms. Firstly, for normal dirt and normal Deposits of liquid acids are used in canisters to be delivered. Either this will be liquid acids as an active ingredient, an iron and / or manganese dissolving compound added shortly before use, or else it will this connection timed afterwards for cleaning the drinking water systems used.

Von Nachteil sind die hohen Transportkosten infolge des hohen Gewichtanteils von Wasser. Wird beispielsweise Was­ serstoffperoxyd als Reiniger verwendet, ist ein normaler Versand nicht möglich, weil es sich um eine recht gefähr­ liche Verbindung handelt. Des weiteren sind diese flüssi­ gen Reiniger nur für den beschränkten Einsatz bei norma­ ler Verschmutzung geeignet. Zum Lösen eisen- und/oder man­ ganhaltiger Ablagerungen und Verockerungen ist ein geson­ dert zu beziehender Wirkstoff erforderlich; dieser kann dem flüssigen Wirkstoff nicht schon vor dem Transport zu­ gemischt werden, weil er nach kurzer Zeit von dem Reini­ ger zersetzt wird.The high transport costs due to the high weight of water. For example, What Use of peroxide as a cleaner is normal Shipping not possible because it is quite dangerous connection. Furthermore, they are liquid gene cleaner only for limited use at norma Suitable for pollution. To solve iron and / or one Complete deposits and blockages is a separate active substance to be obtained is required; this can the liquid active ingredient before transport be mixed, because after a short time the Reini is decomposed.

Der Erfindung liegt die Aufgabe zugrunde, einen zum billi­ gen und einfachen Versand geeigneten Reiniger bereitzustel­ len, der auch für mangan- und/oder eisenhaltige Ablagerun­ gen und Verockerungen einsetzbar ist.The invention has for its object one for billi suitable and easy shipping to provide suitable cleaners len, also for manganese and / or ferrous deposits conditions and blockages can be used.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruches 1 gelöst. Nach Lehre der Erfindung wird zum Versand eine Abpackung, bestehend aus zwei Teilpackungen verwendet, von denen die eine ein flüssigkeitsdichtes Be­ hältnis darstellt, das mit einer festen anorganischen Säure und/oder einem sauren Salz in Pulver- oder Granulat­ form gefüllt ist. Die zweite Teilpackung enthält die eben­ falls einen Feststoff enthaltende Wirkomponente für eisen­ und manganhaltige Verockerungen in Trinkwasseranlagen. Mit dieser, da kein Wasser enthaltenden und daher leichten Ab­ packung ist ein billiger und einfacher Transport eines Rei­ nigungsmittels beispielsweise durch die Post zu einem Be­ steller möglich, der darüber hinaus mit dem Einsatzgebiet für den Reiniger nicht auf normale Verschmutzung beschränkt ist, sondern im Bedarfsfalle auch schwerlösliche eisen- und/ oder manganhaltige Verockerungen relativ schnell und einfach ablösen kann. Je nach Ausbildung der zweiten Wirkkomponen­ te ist zugleich eine desinfizierende und/oder desodorieren­ de Wirkung erforderlichenfalls möglich.This object is achieved by the subject of claim 1 solved. According to the teaching of the invention Dispatch of a package consisting of two partial packages used, one of which is a liquid-tight Be Ratio represents that with a solid inorganic Acid and / or an acid salt in powder or granules  form is filled. The second part pack contains them if an active component containing a solid for iron and manganese-containing blockages in drinking water systems. With this, since no water-containing and therefore easy from pack is a cheap and easy transportation of a rei cleaning agent, for example, by post to a Be possible, who is also involved with the area of application for the cleaner not limited to normal soiling but, if necessary, also poorly soluble iron and / or manganese-containing blockages relatively quickly and easily can replace. Depending on the formation of the second active components te is also a disinfectant and / or deodoriser de Effect possible if necessary.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Er­ findung sind in den Unteransprüchen gekennzeichnet.Appropriate refinements and developments of the Er invention are characterized in the subclaims.

BeispieleExamples

1. Ein Trinkwasserbehälter von 1000 m3 Volumen, dessen was­ serbenetzte Flächen aus Beton bestanden, war mit einer ca. 0.5 bis 1 mm dicken Schicht aus Eisenoxidhydrat und Mangan-IV-oxid inkrustiert. Wenige Sekunden nach Auf­ sprühen einer wässrigen Lösung der erfindungsgemäßen Mischung entfärbte sich der ursprünglich tief schwarz­ braune Belag und konnte leicht abgewaschen werden.1. A drinking water container with a volume of 1000 m 3 , the surface of which was wetted with concrete, was incrusted with an approximately 0.5 to 1 mm thick layer of iron oxide hydrate and manganese IV oxide. A few seconds after spraying on an aqueous solution of the mixture according to the invention, the originally deep black-brown coating discolored and could be easily washed off.

2. Eine Rohrleitung aus Eisen mit einer Nennweite von 1 Zoll und einer Gesamtlänge von 20 Metern war durch Anlagerun­ gen von Calciumcarbonat und Mangan-IV-oxid fast völlig verstopft. Durch Spülen mit einer wässrigen Lösung der erfindungsgemäßen Mischung konnte der Rohrquerschnitt wieder völlig freigelegt werden. 2. An iron pipe with a nominal size of 1 inch and a total length of 20 meters was due to annexation calcium carbonate and manganese IV oxide almost completely clogged. By rinsing with an aqueous solution of mixture according to the invention could the pipe cross section be completely exposed again.  

3. Eine Sprühkammer von 30 m3 Rauminhalt hatte auf den Wänden und auf allen Einbauten einen 2 bis 3 mm dicken Belag von sulfidhaltigem Eisenoxid. Durch Einsatz einer wässri­ gen Lösung der erfindungsgemäßen Mischung konnte eine Entkrustierung ohne störenden Schwefelwasserstoffgeruch vorgenommen werden.3. A spray chamber with a volume of 30 m 3 had a 2 to 3 mm thick coating of sulfide-containing iron oxide on the walls and on all internals. By using an aqueous solution of the mixture according to the invention, decrusting could be carried out without an annoying odor of hydrogen sulfide.

4. Die erfindungsgemäße Mischung hat eine deutliche Abtö­ tungswirkung auf Mikroorganismen, wie z.B. Algen, stark geruchsbildende Pilze und/oder Bakterien. Teile eines offenen Filterbeckens, die durch Schleimbildner stark kontaminiert waren, konnten durch den Einsatz einer wäss­ rigen Lösung der erfindungsgemäßen Mischung sauber und geruchlos gemacht werden.4. The mixture according to the invention has a clear kill effect on microorganisms, e.g. Algae, strong odor-causing fungi and / or bacteria. Parts of a open filter basin, strongly affected by slime formers were contaminated by using an aq clean solution of the mixture according to the invention clean and be made odorless.
