Dans la production industrielle moderne, le bon fonctionnement des chaudi\u00e8res et des syst\u00e8mes d'eau de refroidissement influe directement sur la s\u00e9curit\u00e9 des \u00e9quipements, leur efficacit\u00e9 \u00e9nerg\u00e9tique et leur dur\u00e9e de vie. Le contr\u00f4le de la teneur en fer dans l'eau est une \u00e9tape essentielle pour l'\u00e9valuation de sa qualit\u00e9, ainsi que pour la pr\u00e9vention de la corrosion et de l'entartrage. Les ions ferriques peuvent provenir de la corrosion des canalisations, de la pollution de l'eau brute ou d'un traitement inad\u00e9quat. Une accumulation excessive d'ions ferriques r\u00e9duit l'efficacit\u00e9 du transfert thermique, provoque une corrosion localis\u00e9e et acc\u00e9l\u00e8re la d\u00e9t\u00e9rioration des \u00e9quipements. Par cons\u00e9quent, la d\u00e9termination pr\u00e9cise de la teneur en fer est primordiale pour garantir la s\u00e9curit\u00e9 du syst\u00e8me et optimiser la gestion de la qualit\u00e9 de l'eau.<\/p>\n
