A method and an apparatus are provided for testing the efficiency of a cleaning procedure for a filter in a filtering system. After the cleaning procedure (21) of the filter, the filter pores contain a fluid (22). The system is pressurized (23), and a decay in pressure over a predetermined time period is measured (24). Based on the pressure decay, it is determined whether or not the cleaning procedure has been effective (25); a pressure decay smaller than a predetermined threshold value indicates that the cleaning procedure has not been effective.

L'invention concerne un procédé et un appareil destinés à tester l'efficacité d'une procédure de nettoyage d'un filtre dans un système de filtration. Après réalisation de la procédure de nettoyage (21) du filtre, les pores du filtre contiennent un fluide (22). Le système est mis sous pression (23), puis la chute de pression est mesurée (24) sur une période déterminée. Sur la base de la chute de pression, on détermine si la procédure de nettoyage a été efficace (25) ou non, une chute de pression plus faible qu'une valeur de seuil déterminée indiquant que la procédure de nettoyage n'a pas été efficace.
