A method for sterilisation and cleaning of water supply systems and areas, in particular in treatment plants, pipe systems and in swimming and bathing pool units and a device for carrying out the same are disclosed. An embodiment of said method is characterised by the steps: (1) establishment of a closed circuit between two points of the water supply system or the water supply area, (2) introduction of a given amount of a disinfecting material in the form of an aqueous rinsing solution comprising a chlorine oxide, a halogen and/or a peroxide for disinfection and cleaning, (3) disinfection and cleaning of the pipes, filters and filtration materials in the system including charcoal filters with or without adsorptive properties, with periodic circulation of the rinsing solution in the closed circuit at defined time intervals, (4) draining and disposal of the aqueous rinsing solution and (5) re-establishment of the original water circuit.
L'invention concerne un procédé de dégermage et de nettoyage de systèmes et de surfaces d'alimentation en eau, notamment dans les installations d'épuration, les systèmes de tuyaux et les installations de piscines et bassins de bain. L'invention concerne également un dispositif correspondant. Une variante du procédé selon l'invention consiste : (1) à construire un circuit fermé entre deux points du système ou de la surface d'alimentation en eau; (2) à ajouter une quantité prédéterminée d'un agent désinfectant se présentant sous forme de solution de rinçage aqueuse contenant de l'oxyde de chlore, des halogènes et/ou du peroxide et destinée à dégermer et nettoyer ; (3) à dégermer et à nettoyer les tuyaux, filtres et matériaux filtrants du système, y compris les charbons de filtration avec et sans propriétés d'adsorption, la solution de rinçage circulant périodiquement en circuit fermé à intervalles de temps déterminés; (4) à vider et à rejeter la solution de rinçage aqueuse et (5) à rétablir le circuit d'eau initial.
