Abstract
A method of charging, coagulating, and filtering out particulates in a fluid. In this method, impurity particulates typified by coloring matter particulates can be efficiently removed without inducing clogging and without the need of maintenance for a long time. Also, a filter element used in this method and a fluid-filtering device are offered. The whole filtering layer of the filter element is made of a conductive layer having numerous voids passing the fluid, or the filter element has plural filtering layers of a conductive material. A filtering layer made of a conductive material is used as an electrically charging electrode.
