1. A method for removing airborne particulates from an aerosol stream, comprising the steps of(a) saturating said aerosol stream with water vapor;
- (b) supersaturating said saturated aerosol stream for a time sufficient to permit condensation of said water vapor upon, and growth of said particulates; and
(c) scrubbing said supersaturated aerosol stream, while maintaining said stream at supersaturation, whereby to remove said particulates therefrom.

Abstract
Disclosed herein is a method for removing airborne particulates from an aerosol stream by first humidifying said aerosol with steam, and then cooling said aerosol with water to saturation temperature. Thereafter, the saturated aerosol is adiabatically cooled to a supersaturated state and maintained at supersaturation for a time sufficient to permit the growth and removal thereof of said particulates. Further disclosed is an apparatus adapted for practicing the method of the present invention and employing charged droplet scrubbing techniques to remove said particulates.
