An emissions reduction stack includes a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates. The process of condensation increases the efficiency of the particulate filtration process conducted by the WESP.
