A device for remediation of gaseous or aerosol streams includes an elongated duct, at least one high potential electrode and at least one low potential electrode. The elongated duct defines a bore through which axially flows a gaseous or aerosol stream which is treated by the device to remove pollutants or particulates therefrom. A shaft rotatable within the bore of the duct includes a plurality of pins extending radially therefrom, the shaft and the pins constituting the high potential electrode. The duct may similarly include a plurality of pins extending radially into the interior bore of the duct, whereby the duct and the pins constitute the low potential electrode. The shaft is rotated by a motor relative to the duct, or the duct and shaft may be rotated together by the motor. The high and low potential electrodes are connected to a high voltage power source to effect a corona discharge between the high and low potential electrodes.
