Abstract
(EN)
This filtration membrane processing device for processing a filtration membrane (1) with ozone is provided with: a first supply unit (3) for supplying an ozone-containing fluid to the filtration membrane (1); a measurement unit (8) for obtaining a measurement (H) based on the pressure on the filtration membrane (1); and a control unit (11) for adjusting, on the basis of a change in the measurement (H) obtained by the measurement unit (8), the amount of the ozone-containing fluid to be supplied by the first supply unit (3).
(FR)
Ce dispositif de traitement de membrane de filtration pour traiter une membrane de filtration (1) avec de l'ozone est pourvu : d'une première unité d'alimentation (3) pour fournir un fluide contenant de l'ozone à la membrane de filtration (1); une unité de mesure (8) pour obtenir une mesure (H) sur la base de la pression sur la membrane de filtration (1); et une unité de commande (11) pour ajuster, sur la base d'un changement de la mesure (H) obtenu par l'unité de mesure (8), la quantité de fluide contenant de l'ozone devant être fournie par la première unité d'alimentation (3).
(JA)
