Title (EN) A FILTER APPARATUS AND A METHOD FOR REMOVING DISSOLVED ORGANIC COMPOUNDS FROM A WATER BASED LIQUID
(FR) APPAREIL DE FILTRATION ET PROCÉDÉ D'ÉLIMINATION DE COMPOSÉS ORGANIQUES DISSOUS CONTENUS DANS UN LIQUIDE À BASE D'EAU
Abstract:
(EN) A filter apparatus (11) for removing dissolved organic compounds from a water based liquid, comprising at least one filter unit (12, 20) in the form of a container (13, 21) in which an inlet (14, 22, 23) and an outlet (16, 17, 24) is provided, a filter bed (25) being arranged in the at least one container between the inlet and the outlet, the filter bed comprising at least one layer of an adsorbent comprising an amorphous precipitated silica material, wherein the amorphous precipitated silica material has a porosity with an average pore width of less than 10 nm.
(FR) L'invention concerne un appareil de filtration (11) permettant d'éliminer des composés organiques dissous contenus dans un liquide à base d'eau, comprenant au moins une unité filtrante (12, 20) sous la forme d'un récipient (13, 21) comportant une entrée (14, 22, 23) et une sortie (16, 17, 24), un lit filtrant (25) étant disposé dans ledit récipient entre l'entrée et la sortie, le lit filtrant comportant au moins une couche d'un adsorbant comprenant un matériau de silice précipitée amorphe, le matériau de silice précipitée amorphe ayant une porosité dont la largeur de pore moyenne est inférieure à 10 nm.
