A monitoring system and a method for monitoring a reverse osmosis (RO) membrane in an RO unit is capable of detecting the formation of mineral salt crystals on the surface of the RO membrane. The monitoring system includes a reverse osmosis monitoring cell coupled to the RO unit so as to receive a sample stream taken from either the feed stream to, or the concentrate stream from, the RO unit. The cell has a visually-observable RO membrane that is visible to an imaging system that creates and collects images of the visually- observable RO membrane, and that conveys an image data signal to a data processing system that is operable to translate the image data signal into visual images for display, and to correlate the data in the image data signal with a scaling condition on the RO membrane in the RO unit.

L~invention a pour objet un système et un procédé de surveillance d~une membrane à osmose inverse (OI) dans une unité OI pouvant détecter la formation de cristaux de sel minéral à la surface de la membrane. Le système de surveillance comprend une cellule de contrôle d~osmose inverse couplée à l~unité OI de manière à recevoir un flux-test du flux d~entrée vers l~unité OI ou du flux concentré sortant de l~unité OI. La cellule possède une membrane OI visuellement observable pouvant être visualisée par un système d~imagerie qui en crée et recueille des images et qui transporte un signal de données d~image vers un système de traitement de données pouvant être manAEuvré de manière à traduire le signal de données d~image en images visuelles pour affichage et à comparer les données du signal de données d~image avec l~état de la membrane OI de l~unité OI.
