There is described a method for the starting up of a filtration plant for the filtration of a process liquid, after cleaning of the filtration plant, and a filtration plant which is arranged to be able to started up in accordance with this method. A secondary liquid supply unit connected to the post-treatment equipment during the starting up of the plant provides a flow of e.g. sterilised water to the post-treatment equipment, so that this can be held in a condition in which it is ready for operation. Thereafter, the process liquid is led to the filtration equipment, and the flow of liquid from the secondary liquid supply unit to the post-treatment equipment is shut off when a flow of filtered process liquid is obtained, and which thereafter replaces the liquid from the secondary liquid supply unit.
L~invention concerne un procédé de démarrage d~un dispositif de filtration destiné à la filtration d~un liquide de traitement, après le nettoyage du dispositif de filtration, ainsi qu~un dispositif de filtration conçu pour démarrer selon ce procédé. Une unité d~alimentation en liquide secondaire reliée au dispositif de post-traitement introduit lors du démarrage du dispositif un flux, par exemple d~eau stérilisée, au dispositif de post-traitement, de manière à le maintenir à l~état prêt à fonctionner. Le liquide de traitement est ensuite dirigé vers le dispositif de filtration et le flux de liquide issu de l~unité d~alimentation en liquide secondaire dirigé vers le dispositif de post-traitement est fermé après l~obtention d~un flux de liquide de traitement filtré, ce dernier remplaçant par la suite le liquide issu de l~unité d~alimentation en liquide secondaire.
