ABSTRACT:
A filter for removing finite particles from a fluid is comprised of a plurality of magnetic perforated plates, negatively, electrostatically charged, perforated plates, and positively, electrostatically charged, perforated plates with filter media disposed between the plates. The plates are disposed in succession in the path of fluid flow. The fluid flows through the perforations in the plates, and finite particles are removed therefrom by the interaction of those particles with force fields generated by the plates. Particles are further removed from the fluid by the action of the filter media. Also, a system control prevents any fluid from passing through the filter when an insufficient charge is present on the electrostatically charged plates.
