Abstract

PURPOSE:To easily and effectively clean and regenerate the electromagnetic filter, by flowing the backwash fluid through the electromagnetic filter element, and at the same time, by applying the alternating magnetic field of stepped waveform suddenly altering its direction between normal and reverse directions, to this element. CONSTITUTION:The backwash fluid C is introduced into the non-magnetic metallic vessel 12 and is passed through the vessel 12; synchronously with this fluid flow, the attenuation alternating electric current of stepped wavefom is supplied to the electromagnetic coil 20 in order to apply to the filter element 14 the attenuation alternating magnetic field suddenly altering its direction between the normal and reverse directions. That is, by the first stepped magnetic field D, the magnetic particle 26 on one side of the steel wire 28 constituting the element 14 is easily and effectively released by utilizing the isopolar magnetic repulsion, and the released magnetic particle 26 is washed away by the fluid C. Next, the magnetic field D in the direction reverse to that of the first magnetic field D is applied in order to similarly easily release the particle 26 adhering the another side of the wire 28. Hereupon, the flowing direction of the fluid C is also reversed synchronously with the inversion of the magnetic field D; hereby, the once relased particle 26 can be more easily washed away in regenerating the element 14.
