    Dec 15, 2018 Abstract. The elemental mercury (Hg0) removal performance of wet electrostatic precipitator (WESP) was studied on a lab-scale experimental device. Increasing voltage in WESP promoted the Hg0 oxidation because higher-energy electrons in the electric field accelerated the discharge of O2 and H 2 O to form free radicals like O, O 3 and OH. The
