ABSTRACT:
A fluid, such as air or water, carrying suspended solids is directed between a pair of oppositely charged, corrugated surfaces in order to subject the flow to an undulating action that increases the frequency with which the solid particles impinge against one another, thereby increasing the rate of flocculation of the solids. In the case of airborne particles, the corrugated surfaces are arranged in an upright condition so that the flocculated particles attracted to one or the other of such surfaces gravitate therefrom into a conveying mechanism that delivers such particles to a collecting receptacle. In the case of liquid-borne particles, the flow is forced to travel upwardly against the force of gravity after passing between the surfaces, thereby encouraging the flocculated particles to settle out into a sump that is associated with the uphill flow passage. In each case, two sets of charged surfaces may be utilized, the first having at least one of its surfaces insulated from the flow for electrostatic action only, while the second has neither surfaces so insulated for electrolytic action.
