Title
(EN) METHOD OF PREPARING A WATER TREATMENT PRODUCT
(FR) PROCEDE DE PREPARATION D'UN PRODUIT DE TRAITEMENT DE L'EAU
Abstract
(EN) There is provided a method of preparing a water treatment product, which method comprises the steps of: (i) impregnating a high surface area material with an iron salt solution; (ii) optionally oxidising the iron salt; and (iii) treating the impregnated material with a base to provide a hydrated ferric oxide coating thereon, wherein the resulting product is recovered without forced drying.
(FR) La présente invention se rapporte à un procédé de préparation d'un produit de traitement de l'eau qui comprend les étapes suivantes : (i) imprégnation d'une matière à aire de surface élevée avec une solution d'un sel ferreux ; (ii) oxydation éventuelle du sel ferreux ; et (iii) traitement de la matière imprégnée avec une base de manière à former à sa surface un revêtement d'oxyde ferrique hydraté, le produit résultant étant récupéré sans séchage forcé.
