An electrode for use in an electrostatic precipitator comprising a conductive central portion to which are attached a plurality of conductive disc-shaped elements each having sharp points spaced around its circumference and a plurality of openings near its center. The central portion passes through the centers of each thus locating them parallel to one another along the central portion. The disc-shaped elements are conical or convex in shape, and oriented with their rims raised above their centers so that any water that collects on them runs out through the openings and down the central portion of the electrode thus reducing or eliminating arcing between the electrode and a collector in the electrostatic precipitator. A high voltage feedthrough and the electrode assembly are configured as one contiguous chamber with holes around the interior walls of the high voltage feedthrough to alternately receive liquid and gas.
