Title (EN) METHOD AND MEANS FOR PURIFICATION OF WATER BY REVERSE OSMOSIS
(FR) PROCÉDÉ ET DISPOSITIF DE PURIFICATION DE L'EAU PAR OSMOSE INVERSE
Abstract: front page image
(EN)The present invention is for method and means for purification of water using reversed osmosis. Water is forced through a membrane element (10) under pressure, which is obtained by a high pressure pump (2), where the water which is supplied to the element (10) is both from the outside supplied, unpurified water and internally circulated water that has passed by the element at its inlet side. The high pressure pump operates intermittently and the quantity of water that is circulated internally is at least as large as the quantity of water that is supplied from the outside. After that the pressure has been reduced there is a time delayed flush cleaning of the element (10) by flushing with water that is supplied from outside.
(FR)L'invention concerne un procédé et un dispositif de purification de l'eau par osmose inverse. L'eau est introduite sous pression dans un élément de membrane (10), la pression étant produite par une pompe à haute pression (2). L'eau introduite dans l'élément (10) est à la fois de l'eau non purifiée provenant de l'extérieur et de l'eau circulant intérieurement ayant passé par l'élément par le côté de l'orifice d'admission. La pompe à haute pression fonctionne de manière intermittente et la quantité d'eau circulant intérieurement est au moins aussi importante que la quantité d'eau provenant de l'extérieur. Une fois la pression réduite, on procède à un nettoyage temporisé par chasse de l'élément (10) en utilisant de l'eau provenant de l'extérieur.
