Abstract

Dispositif de purification (1) d’un liquide comprenant un circuit d’alimentation (2) en liquide, un circuit de distribution (6) d’un liquide purifié, un circuit d’évacuation (5) d’un liquide concentré, et un système de filtration du liquide (3) par osmose inverse comprenant une entrée d’alimentation (31) reliée au circuit d’alimentation (2), une première sortie (32) de liquide concentré relié au circuit d’évacuation (5) et une deuxième sortie (33) de liquide purifié reliée au circuit de distribution (6), ledit dispositif étant caractérisé en ce qu’il comprend également : un circuit de recirculation (7a, 7b) du liquide purifié au travers du système de filtration (3) depuis le circuit de distribution (6) vers la deuxième sortie (33) du système de filtration (3) et depuis l’entrée d’alimentation (31) du système de filtration (3) vers le circuit d’évacuation (5) de façon à rincer le système de filtration (3) après l’arrêt du dispositif de purification (1). Figure 1Device (1) for purifying a liquid comprising a liquid supply circuit (2), a distribution circuit (6) for a purified liquid, an evacuation circuit (5) for a concentrated liquid, and a liquid filtration system (3) by reverse osmosis comprising a supply inlet (31) connected to the supply circuit (2), a first outlet (32) for concentrated liquid connected to the evacuation circuit (5) and a second purified liquid outlet (33) connected to the distribution circuit (6), said device being characterized in that it also comprises: a recirculation circuit (7a, 7b) for the purified liquid through the filtration system (3 ) from the distribution circuit (6) to the second outlet (33) of the filtration system (3) and from the supply inlet (31) of the filtration system (3) to the evacuation circuit (5) so as to rinse the filtration system (3) after stopping the purification device (1).
