Abstract

Abstract Translated from French Membrane de filtration, formée d'une matière minérale frittée, comprenant une ou plusieurs couches formant couche de filtration et constituées de grains solidarisés entre eux. La rugosité moyenne à la surface de la couche de filtration externe, sur une distance au moins égale à 5 fois la dimension moyenne des grains, est inférieure à 0,20 fois cette dimension moyenne au niveau de cette surface. Application à la filtration de liquides alimentaires ou de gaz chauds ou corrosifs. Filtration membrane, formed of a sintered mineral material, comprising one or more layers forming a filtration layer and made up of grains joined together. The average roughness at the surface of the external filtration layer, over a distance at least equal to 5 times the average size of the grains, is less than 0.20 times this average size at this surface. Application to the filtration of edible liquids or hot or corrosive gases.
