PURPOSE: An antibacterial porous filter and a fluid treatment method using the same are provided to prevent a film from being contaminated and blocked by bacteria cohered on the surface of film for filtering fluid and removing bacteria. CONSTITUTION: An antibacterial porous filter comprises a first porous media and a second porous media. The first porous media has upstream surface, downstream surface and bulk between the upper stream surface and the downstream surface. The first porous media includes particle including silver in the bulk. The particle has the average diameter of 0.2-20 micrometers. The second porous media has upstream surface, downstream surface and bulk between the upper stream surface and the downstream surface. The second porous media has smaller mean flow pore(MFP) size than the mean diameter of particles within the first layer. The downstream surface of the first porous media contacts the upper stream surface of the second porous media. |
