FILTERING METHOD OF MICRO-METALLIC PARTICLES WHICH ARE SUSPENDED IN FLUID

摘要

PURPOSE: A filtering method of micro-metallic particles which are suspended in a fluid is provided which increases filtration efficiency by orientation packing bended filter medium of amorphous ribbon into a filter cartridge, and consistently maintains a high filtration efficiency by effectively performing back washing after filtration. CONSTITUTION: In a method for filtering micro-metallic particles in a fluid using electromagnetic principle using an external magnetic field, the filtering method of the micro-metallic particles suspended in the fluid is characterized in that the fluid is filtered by orientation packing the bended amorphous ribbon or fiber(6) into a filter cartridge(5) so that a length direction of the amorphous ribbon or fiber(6) is parallel to a flow direction of the fluid after bending a filter medium of amorphous ribbon or fiber(6), wherein a packing ratio of the amorphous or fiber to be packed into the filter cartridge(5) is 0.5 to 5% in weight fraction.
