A composite filter medium for removing particulates in the 3 to 4 micron range as well as dissolved chemical contaminants from a fluid. The filter medium contains an adsorbent layer (11) for removing dissolved contaminants, and a hydrophilic layer (19) for removing particulates. In one embodiment, the adsorbent layer comprises a supporting substrate (12), adsorbent particles (16), and binder particles (18). The filter medium is characterized by a mean flow pore diameter of about 1 to 10 microns, a bubble point of about 3 to 15 microns, and an air permeability of about 0.5 to 7 liters per minute/cm2 with a pressure drop of about 0,1 bar. The composite filter medium may be used in the construction of potable water filters for the removal of potentially hazardous microorganisms.

L'invention porte sur un milieu filtrant composite destiné à retirer d'un fluide des matières particulaires de l'ordre de 3 à 4 microns, ainsi que des contaminants chimiques dissous. Le milieu filtrant comporte une couche (11) adsorbante pour retirer les contaminants dissous et une couche (19) hydrophile pour retirer les matières particulaires. Selon une réalisation, la couche adsorbante comprend un substrat (12) de support, des particules (16) adsorbantes et des particules (18) de liant. Le milieu filtrant se caractérise par un diamètre moyen de pore d'écoulement compris entre environ 1 et environ 10 microns, un point de bulle compris entre environ 3 et 15 microns et une perméabilité à l'air d'environ 0,5 à 7 litres par minute/cm<2> avec une chute de pression d'environ 0,1 bar. Le milieu filtrant composite peut être utilisé dans la fabrication de filtres pour l'eau potable destinés à éliminer des micro-organismes potentiellement dangereux.
