Title (EN) SYSTEM AND METHOD FOR WATER PURIFICATION WITH AUTOMATIC PURGE
(FR) SYSTÈME ET PROCÉDÉ DE PURIFICATION D'EAU AVEC PURGE AUTOMATIQUE
Abstract:
(EN) The invention concerns a treated water purification system (107) comprising a water flow loop (110), said loop (110) being closed onto a tank (10) of treated water to purify, and said loop (110) successively comprising, in the direction of flow of the water downstream of the tank (10), at least one pump means (102), at least one first filtration means (103), at least one second filtration means (104) and at least one point of use (U), the system (107) being characterized in that it further comprises at least one diversionary pipe (112) linking the first filtration means (103) to the tank (10), and a loop return pipe (114) linking the second filtration means (104) to the tank (10). Method for use of such a system.
(FR) Cette invention concerne un système de purification d'eau traitée (107) comprenant une boucle fermée d'écoulement de l'eau (110), ladite boucle (110) étant fermée sur un réservoir (10) d'eau traitée à purifier, et ladite boucle (110) comprenant successivement, dans le sens de l'écoulement de l'eau en aval du réservoir (10), au moins un moyen formant pompe (102), au moins un premier moyen de filtration (103), au moins un second moyen de filtration (104) et au moins un point d'utilisation (U) ; le système (107) est caractérisé en ce qu'il comprend par ailleurs au moins un conduit de dérivation (112) reliant le premier moyen de filtration (103) au réservoir (10), et un conduit de retour en boucle (114) reliant le second moyen de filtration (104) au réservoir (10). Cette invention concerne également un procédé d'utilisation de ce système.
