Wet electrostatic precipitator uses electrostatic forces to remove particulate.  It is used to treat gas streams with sub-micron particulate, aerosols, or fumes.  These can include heavy metals such as lead, arsenic, or cadmium, condensed acid aerosols like sulfur trioxide (SO3), or condensed volatile organic compounds (VOC’s).  The use of electrostatic forces minimizes energy costs compared to Venturi scrubbers or bag houses, which require large amounts of energy to overcome resistance to air flow.   Wet electrostatic precipitators are used in a wide range of applications including, hazardous and medical waste incinerators, metals refining, sulfite pulp mill recovery boilers, copper roasters, sulfuric acid plants, and wood dryers including oriented strand board (OSB), medium density fiber board (MDF), or pellet mill dryers.
