PROCEDE DE REALISATION D'UN FILTRE A MEMBRANE
The invention relates to a process for producing a membrane filter comprising the steps of selecting a honeycomb monolith with a network of channels separated by porous channel walls and the deposition on these walls of a membrane that adheres to the wall, obtained by a coating operation during which some of the walls of the monolith are placed in contact with an aqueous suspension of a sinterable powder of a constituent material of the monolith then by drying and finally by calcining the coated monolith. The membrane is obtained by repeating the coating operation, the weight concentration of sinterable powder in the aqueous suspension being reduced at each new operation, and the calcination is carried out at a temperature below 1000°C.
