Establishment of industries - Import export

Dr. Frederick Cottrell developed the first wet electrostatic precipitator (WESP) in 1907 to control sulfuric acid mist from a copper smelting process in Pinole, California.Since that time WESP technology has become well-established in both industrial and utility applications around the world to remove sub-micron particulate, condensables, and acid mist as a final polishing device in an air pollution control system where an upstream dry ESP, fabric filter or wet scrubber cannot capture the sub-micron particulate due to its small size.
