Description

Die Erfindung betrifft Mittel zur Reinigung, Desinfektion und Wartung von Trinkwasser- und Brunnen-Anlagen und Anlagen der Getränkeindustrie.The invention relates to agents for cleaning, disinfection and maintenance of drinking water and well systems and facilities of the Beverage industry.

Bekanntlich bilden sich in Trinkwasser-Anlagen, z.B. auf den Wänden von Behältern, Brunnen, in den Armaturen, Filtern, Wasseraufbereitungsanlagen und Rohrsystemen, Verockerungen oder Ablagerungen, bei denen es sich meist um eisen- mangan- und kalziumhaltige Mischoxyde und Mischkarbonate handelt, die häufig außerdem mit Algen und Mikroorganismen durchsetzt sind. Ähnliche Ablagerungen bilden sich in Wassertanks der Nahrungs- und Getränkeindustrie.As is well known, drinking water systems, e.g. on the Walls of containers, wells, in the fittings, filters, Water treatment plants and pipe systems, clogging or deposits, which are mostly iron manganese and calcium-containing mixed oxides and mixed carbonates, which is also often infiltrated with algae and microorganisms are. Similar deposits form in the water tanks of the Food and beverage industry.

Es sind auch Reinigungsmittel bekannt, die speziell für die Entfernung derartiger Beläge konzipiert sind. An diese Reini­ gungsmittel werden hohe Anforderungen in Bezug auf Wirksam­ keit, Gesundheitsverträglichkeit und Abwasserverhalten, Sicherheit der Handhabung, Korrosionsverhalten usw. gestellt. Häufig sind die Anforderun­ gen gegensätzlicher Natur, z.B. würden starke Säuren oft den Abbau eines Belages beschleunigen. Aus Gründen der Handhabungs­ sicherheit, der Gesundheitsverträglichkeit von Restmengen im Trinkwasser und der Eindämmung der Korrosion sind der Ver­ wendung von starken Säuren jedoch enge Grenzen gesetzt.There are also cleaning agents known specifically for the Removal of such deposits are designed. To this Reini agents become high requirements in terms of effectiveness health, health tolerance and wastewater behavior, safety of the Handling, corrosion behavior, etc. The requirements are frequent contrary in nature, e.g. strong acids would often Accelerate dismantling of a covering. For the sake of handling safety, the health tolerance of residual quantities in drinking water and the containment of corrosion are the ver However, the use of strong acids sets narrow limits.

Aus der deutschen Patentschrift 20 40 546 ist ein für die vor­ bezeichneten Zwecke sehr gut geeignetes Reinigungsmittel be­ kannt, das L-Ascorbinsäure als Hauptkomponente enthält. Bei diesem Reinigungsmittel war jedoch das Problem der Wieder­ verkeimung noch nicht optimäl gelöst.From German patent specification 20 40 546, one for the front designated purposes very suitable cleaning agent knows that contains L-ascorbic acid as the main component. With this detergent, however, the problem was again germs have not yet been optimally resolved.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Mittel zur Reinigung, Desinfektion und Wartung von Trinkwasseranlagen und Anlagen der Getränke- und Nahrungsmittelindustrie bereit­ zustellen, mit dem Verockerungen und Ablagerungen leicht und wirkungsvoll entfernbar sind, das sicher handhabbar ist, den gesetzlichen Anforderungen zum Schutze der Gesundheit entspricht und eine Wiederverkeimung nach der Reinigung wirk­ sam verhindert.The invention is therefore based on the object of an agent for cleaning, disinfection and maintenance of drinking water systems and plants in the food and beverage industry to deliver with the blockages and deposits easily and are effectively removable, which is safe to handle, the legal requirements for the protection of health corresponds and a recontamination after cleaning is effective sam prevented.

Überraschenderweise wurde nun ein Mittel gefunden, das eine sehr gute Lösung der vorbezeichneten Aufgabe darstellt und das gekennzeichnet ist durch:Surprisingly, a remedy has now been found, the one represents a very good solution to the aforementioned task and that is characterized by:

74-87 Gew.-% L-Ascorbinsäure oder ein nicht toxisches wasserlösliches Salz davon
11-24 Gew.-% Amidosulfonsäure oder ein nicht toxisches wasserlösliches Salz davon
1-2 Gew.-% Natriumsulfat,
0,01-0,1 Gew.-% Entschäumer für Wasser,
0,01-0,2 Gew.-% Phosphorsäureester,
0,01-0,2 Gew.-% Biozid für wäßrige Reinigungsmittel.74-87% by weight of L-ascorbic acid or a non-toxic water-soluble salt thereof
11-24% by weight of amidosulfonic acid or a non-toxic water-soluble salt thereof
1-2% by weight sodium sulfate,
0.01-0.1% by weight defoamer for water,
0.01-0.2% by weight of phosphoric acid ester,
0.01-0.2% by weight biocide for aqueous cleaning agents.

Die vorstehend angegebenen Gewichtsprozentsätze beziehen sich auf das Gesamtgewicht des angegebenen Mittels.The weight percentages given above relate on the total weight of the specified agent.

Vorteilhaft enthalten die erfindungsgemäßen Mittel 78-82 Gew.% L-Ascorbinsäure oder ein nicht toxisches, wasserlösliches Salz davon und der bevorzugte Gehalt an Amidosulfonsäure oder einem nicht toxischen, wasserlöslichen Salz davon beträgt 16-20 Gew.%. Bei den Salzen der vorbezeichneten Säuren handelt es sich vorzugsweise um das Ammonium-, Natrium oder Kaliumsalz. The agents according to the invention advantageously contain 78-82% by weight. L-ascorbic acid or a non-toxic, water-soluble salt thereof and the preferred content of amidosulfonic acid or a non-toxic, water-soluble salt of which is 16-20 % By weight. The salts of the aforementioned acids are concerned preferably the ammonium, sodium or potassium salt.  

Als Entschäumer verwendet man vorzugsweise ein Polysiloxan und Fettsäure­ ester. Als Phosphorsäureester verwendet man vorzugsweise einen der für die Metalloberflächenbehandlung bekannten reinigenden und korrosionsschützenden Ester und als Biozid benutzt man vor­ zugsweise Benzalkoniumchlorid, Glutardialdehyd und/oder Glyoxal bzw. ein Hydrosulfit-Addukt dieser Aldehyde.A polysiloxane and fatty acid are preferably used as defoamers ester. The phosphoric acid ester used is preferably one of known for the metal surface treatment cleaning and Corrosion-protecting ester and as a biocide are used before preferably benzalkonium chloride, glutardialdehyde and / or glyoxal or a hydrosulfite adduct of these aldehydes.

Zusätzlich können die oben bezeichneten Mittel noch bis zu 0,2 Gew.% eines Fettsäureesters, bis zu 0,2 Gew.% eines Fett­ alkoholalkoxilates und bis zu 0,2 Gew.% Isopropylalkohol ent­ halten.In addition, the funds referred to above can still be up to 0.2% by weight of a fatty acid ester, up to 0.2% by weight of a fat alcohol alkoxylates and up to 0.2% by weight of isopropyl alcohol hold.

Die oben bezeichneten Komponenten können in fester Form ver­ mischt und in dieser Form gelagert und in den Handel gebracht werden. Vor der Anwendung werden sie in Wasser gelöst. Die Anwendungskonzentration beträgt in der Regel 1-10% des Mittels in Wasser, je nach der Stärke der Beläge und der zur Verfügung stehenden Behandlungszeit.The components described above can be used in solid form mixes and stored in this form and put on the market will. They are dissolved in water before use. The Application concentration is usually 1-10% of the In water, depending on the thickness of the coverings and the Available treatment time.

Das Mittel kann auch als 5-10 gew.%ige Stammlösung in den Handel gebracht werden.The agent can also be used as a 5-10% by weight stock solution in the Trade.

Es kann auch zur Verstärkung von stärker sauren Reinigungs­ mitteln, die z.B. Salzsäure und/oder Phosphorsäure enthalten, verwendet werden. Oft ist es auch vorteilhaft, die wäßrige Lösung der erfindungsgemäßen Mittel mit Niederdrucksprüh­ geräten (1-2 bar) aufzutragen. Eine bevorzugte Anwendungs­ konzentration liegt bei 1-5 Gew.%. It can also reinforce more acidic cleaning means which e.g. Contain hydrochloric acid and / or phosphoric acid, be used. It is often also advantageous to use the aqueous one Solution of the agent according to the invention with low pressure spray devices (1-2 bar). A preferred application concentration is 1-5% by weight.  

Mit den erfindungsgemäßen Mitteln können Trinkwasseranlagen, Behälter, Brunnen, Armaturen, Filter, Mikrofilter, Wasser­ aufbereitungsanlagen, Rohrsysteme usw. sehr wirkungsvoll ge­ reinigt und desinfiziert werden und die Zeit bis zur Wieder­ verkeimung kann mit den erfindungsgemäßen Mitteln ganz wesentlich verlängert werden.Drinking water systems, Containers, wells, fittings, filters, microfilters, water processing plants, pipe systems, etc. very effective be cleaned and disinfected and the time until again Germination can be done entirely with the agents according to the invention be significantly extended.
