Abstract
(DE)
Ein Verfahren zur Desinfektion von durch eine Leitung (1) geführtem Trinkwasser durch dosierte Zugabe einer 'freies Chlor' enthaltenden wässrigen Desinfektionslösung besteht aus den folgenden Schritten: eine wässrige Natriumchloridlösung wird in einem 'Vorratsbehälter (4) bereitgehalten, eine bestimmte Menge der NaCl -Lösung wird abhängig von der Menge des durch die Leitung (1) geführten Trinkwassers chargenweise in eine Elektrolysezelle (5) gegeben, die in die Elektrolysezelle (5) gegebene Charge der NaCl -Lösung wird elektrolysiert , die Elektrolyse wird solange durchgeführt, bis das NaCl zumindest teilweise in 'freies Chlor' umgewandelt ist, nach Beendigung der Elektrolyse wird die in der Elektrolysezelle (5) befindliche Desinf ektionslösung in einen Dosierbehälter (9) gegeben und die Desinfektionslösung wird abhängig von der Menge des durch die Leitung (1) geführten Trinkwassers aus dem Dosierbehälter (9) in die Leitung (1) injiziert.
(EN)
The invention relates to a method for disinfecting drinking water which is guided through a pipe (1) by adding an aqueous disinfection solution, which contains free chlorine. Said method consists of the following steps: an aqueous sodium chloride solution is prepared in a container (4), a specific amount of the NaCl solution is introduced, in batches, into the electrolysis cell (5) according to the amount of the drinking water guided through the pipe (1), the NaCl solution is electrolysed in the electrolysis cell (5), electrolysis is carried out until the NaCl is at least partially converted into free chlorine, the disinfection solution contained in the electrolysis cell (5) is introduced into the dosing container (9) when electrolysis is completed and the disinfection solution from the dosing container (9) is injected according to the amount of drinking water guided through the pipe(1).
(FR)
L'invention concerne un procédé de désinfection d'eau potable guidée au travers d'une conduite (1) par addition d'une solution de désinfection aqueuse contenant du chlore libre, consistant à se munir d'une solution de chlorure de sodium aqueuse dans un réservoir (4) ; à introduire de façon discontinue une quantité définie de la solution de NaCl dans une cellule d'électrolyse (5) en fonction de la quantité d'eau potable guidée au travers de la conduite (1) ; à électrolyser la solution de NaCl introduite dans la cellule d'électrolyse (5) ; à réaliser l'électrolyse jusqu'à ce que le NaCl soit au moins partiellement transformé en chlore libre ; à introduire la solution de désinfection contenue dans la cellule d'électrolyse (5) dans un contenant de dosage (9) à la fin de l'électrolyse ; et à injecter la solution de désinfection, du contenant de dosage vers la conduite (1), en fonction de la quantité d'eau potable guidée au travers de la conduite (1).
