Abstract
Abstract Method having electrostatic means for removing particles from a fluid containing the same, the electrostatic means comprising charged electrode means electrically insulated from the fluid so that the electrostatic field thereof draws the particles into exit means of a passage defining means having the fluid therethrough. Such charged electrode means create a plurality of alternately arranged non-uniform fields across the fluid in the passage means so that the particles enter the exit means adjacent the more intense portions of the non-uniform fields, such electrodes also creating electroconvection in said fluid. Such passage means can comprise means for straight laminar flow of the fluid therethrough by being disposed adjacent or in another passage means having a particle receiving fluid stream flow therethrough. Such other passage means can receive particles of opposite polarity to neutralize the electric field created by charged particle separation.
