Abstract

Purifying, sterilising, de-algifying drinking-, bath- or waste-water and water for industrial use, and also oxidation of (in)organic materials, is carried out with Br2 or its oxygenated salts, as aqs. solns. of water-sol. salts, such as NaBr or KBr, which are produced in an electrolysis cell connected with a water-treatment installation and immediately conveyed to the water-treatment installation without any storage. Process obviates accumulation and transport of substances requiring safety precautions. Pref. current supply and switch-off required for electrolysis are coupled with on- and off-switching of water supply pump for treating (waste) water, in a way such that prodn. of chemicals starts with onset of water flow and is interrupted when it ends.

Description

titel: "Verfahren zur Behandlung von wasser mit brom oder dessen Sauerstoffsalzen".Title: "Process for the treatment of water with bromine or its oxygen salts".

Die Erfindung betrifft ein Verfahren zur Behandlung von Wasser, z.B. Trinkwasser, Betriebswasser, Badewasser, Abwasser und dergleichen mit Brom und/oder dessen Sauerstoffsalzen, zwecks Dekontaminierung, Entkeimung, Entalgung, sowie zur Oxydation anorganischer und organischer im Wasser enthaltener Substanzen.The invention relates to a method for treating water, e.g. Drinking water, process water, bathing water, waste water and the like with bromine and / or its oxygen salts, for the purpose of decontamination, disinfection, de-algae removal, as well as for Oxidation of inorganic and organic substances contained in water.

Der Einsatz von Brom und dessen Sauerstoffsalzen zu den gWhsmten Zwecken bei der Behandlung von Wasser verschiedenster Art it bereits mehrfach vorgeschlagen und vereinzelt auch schon angewandt worden.The use of bromine and its oxygen salts for the right purposes in the treatment of water of various kinds it has already been proposed several times and has also been used in isolated cases.

Der Einsatz von Brom und seinen organischen Verbindungen wurde insbesondere im Zusammenhang init der Aufbereitung von Badewasser beschrieben. Das Verfahren hat jedoch bisher nur geringe praktische Bedeutung erlangt0 Dies lag insbesondere daran, dass bei der technischen Handhabung, der Anlieferung und Lagerung, sowie beim Einsatz bestimmte Vorsichtsmassregeln zu beachten sind, um Schäden an den Einrichtungen und gesundheitliche beeinträchtigungen des Bedienungspersonals zu vermeiden.The use of bromine and its organic compounds was particular in connection with the treatment of bathing water. The procedure However, it has so far only achieved little practical importance0 This was particularly the case remember that in terms of technical handling, delivery and storage, as well certain precautionary measures must be observed during use, around Damage to the equipment and health impairments for the operating personnel to avoid.

Diese Nachteile wurden insbesondere dadurch verursacht, dass die Herstellung der zur Behandlung dienenden Stoffe, die in von der Wasserbehandlung ganz getrennten Anlagen erfolgte, die lieferung nach dem behandlungsort unter Einsatz verschiedenartiger Transportmittel, sowie eine längere Lagerung der angelieferten behandlungsmittel und ihre spätere Entnahme unter wechselndem bedarf erfolgten.These disadvantages were caused in particular by the fact that the production the substances used for the treatment, which are completely separate from the water treatment Plants took place, the delivery to the treatment site using different types Means of transport, as well as a longer storage of the delivered treatment agents and their later removal took place with changing needs.

Zur Vermeidung der beim Einsatz von Brom und dessen Sauerstoffsalzen eintretenden Schwierigkeiten und Unannehmlichkeiten wird erfindungsgemäs 5 vorgeschlagen, diese Ohemikalien an Ort und Stelle ihres Verbrauchs in ßorm wässriger Lösungen aus wasserlöslichen Salzen, wie z.bO Natriumbromidf Kaliumbromid und dergleichen in einer mit der Wasserbehandlungsanlage örtlich verbundenen h~lektrolyseaulage herzustellen und ohne Zwischenlagerung oder Vorratsbildung unmittelbar in die zur Wasserbehandlung dienende Anlage zu überführen. bei der Durchführung dieses Verfahrens entsteht also kein vorrat an Chemikalien1 so dass vorsichtsmassnahmen und Sicherheitsvorschriften entfallen, die bei einer Lagerung oder Bevorratung zu beachten sind. Die erzeugung der Uhemikalion kommt vielmehr erst unmittelbar in Gang, wenn die Elektrolyse einsetzt, und endet, wenn dieselbe unterbrochen wird. Zweckmässig wird dabei die für die Elektrolyse erforderliche Stromzuführung, bzw. die Stromabschaltung, mit dem Einschalten und Abschalten der w-Wasserförderpumpe des zu behandelnden Wassers oder Abwassers derart gekoppelt, dass die Erzeugung der Chemikalien mit dem Einsetzen des Wasserflusses unter ständiger Zufügung derselben in die Wasserbehandlungsanlage beginnt und mit der Beendigung des Wasserzuflusses unterbrochen wird. Das Einsetzen oder das Ende des Wasserzuflusses kann dabei z.b. durch einen Strömungswächter geregelt werden.To avoid the use of bromine and its oxygen salts occurring difficulties and inconveniences is proposed according to the invention 5, these chemicals in place of their consumption in form of aqueous solutions from water-soluble salts, such as sodium bromide, potassium bromide and the like in an electrolysis facility that is locally connected to the water treatment plant and without intermediate storage or storage directly in the for To transfer water treatment plant. in performing this procedure there is therefore no stock of chemicals1 so that precautionary measures and safety regulations which have to be observed when storing or stocking up are not applicable. The production Rather, the Uhemicalion only starts immediately, if the Electrolysis begins and ends when it is interrupted. Becomes expedient the power supply required for the electrolysis or the power cut-off, with the switching on and off of the water pump of the water to be treated or sewage coupled in such a way that the generation of the chemicals with the onset of the water flow with constant addition of the same into the water treatment plant begins and is interrupted when the water flow ends. Insertion or the end of the water inflow can e.g. regulated by a flow monitor will.

Die mit Elektroden ausgestattete Elektrolysezelle kann z.B. mit Gleichstrom betrieben werden, der über Transformator und Gleichrichter mit Stromnetz entnommen wird0 Dabei kann die zur Erzeugung des Broms oder Bromsalzes dienende fllektrolysezelle kontinuierlich mit der zu bearbeitenden lösung, z.#. einer atrium-8romid-Lösung, beschickt werden, die durch eine Dosierpumpe aus einem sösungsbehälter entnommen wird. Die in der Elektrolysezelle erzeugten Chemikalien werden alsdann unmittelbar ohne Zwischenschaltung weiterer Pumpen und dörderorgane in das zu behandelnde Wasser weitergeführt. Die bachspeisung der verbrauchten Hatrium-Bromid-bösung in der Slektrolysezelle sowie eine Nachspeisung von Wasser in den als Lösungsbehält er ausgebildeten Natrium-Bromid-Vorratsbehälter kann dabei automatisch bewirkt und geregelt werden0 Zur Behandlung des Wassers können vorteilhaft auch Mischungen von Chlor und Brom, bzw. Mischungen aus den Sauerstoffsalzen der genannten Substanzen verwandt werden. Dabei kann die Erzeugung der zur Behandlung des Wassers dienenden mischungen unter Einsatz von Mischungen aus wasserlöslichen Bromsalzen und wasserlöslichen Ohlorsalzen, z.B. Natriumchlorid, Xaliumchlorid und der gleichen, in Form von für die Elektrolyse brauchbaren wässrigen Lösungen am verbraucherort in den Lösungsbehälter und in die angeschlossene Elektrolysezelle erfolgen,The electrolysis cell equipped with electrodes can be operated with direct current, for example be operated, which is taken from the power grid via transformer and rectifier The electrolysis cell used to generate the bromine or bromine salt can be used continuously with the solution to be processed, e.g. #. an atrium-8romide solution, are charged, which is taken from a solution container by a metering pump will. The chemicals produced in the electrolytic cell are then immediately into the water to be treated without the interposition of further pumps and conveying elements continued. The backfeed of the used sodium bromide solution in the electrolysis cell as well as a replenishment of water in the as a solution tank he trained sodium bromide storage container can thereby automatically effected and 0 Mixtures of Chlorine and bromine, or mixtures of the oxygen salts of the substances mentioned be used. The generation of the water used to treat the water can be used mixtures using mixtures of water-soluble bromine salts and water-soluble ones Chloride salts, e.g., sodium chloride, xalium chloride and the like, in the form of for the electrolysis of usable aqueous solutions at the point of use in the solution container and in the connected electrolysis cell,
