Answer

Electrostatic precipitators have been the air pollution control technology of choice for power generation and industrial processes throughout the world. ESPs are highly efficient dust collectors with proven collection efficiencies of up to 99.99% with guaranteed outlet emissions with minimal pressure loss. In an electrostatic precipitator, particles suspended in the air stream are given an electric charge as they enter the unit and are then removed by the influence of an electric field.
