CERAMIC FILTRATION MEMBRANE
The present invention relates to a ceramic filtration membrane with a porous support (1) formed by sintering aluminum oxide particles and metal oxide particles at a temperature greater than 1300° C. and less than 1500° C., comprising fine aluminum oxide particles with a particle size of less than 10 μm, and coarse aluminum oxide particles with a particle size of 20 μm-150 μm, where the fine aluminum oxide particles represent a percentage by weight. of 3%-10% with respect to the total weight of the porous support (1), the porous support (1) having a porosity greater than 28% with a pore size of 1 μm-7 μm, bending strength greater than 45 MPa and suitable chemical resistance, giving rise to ceramic filtration membranes with ceramic layers (3) having a pore size of 1 nm to 1000 nm.
