Application of Electrostatic Precipitator can be noticed in gas and oil recovery industry where it is required to collect industry generated dust. This equipment uses electrostatic force for its operation. Discharge wires of this system generate electrical field between its dust collecting plates and wires from high voltage and promotes ionization of gas surrounding its discharge wires. Aerosol particles present in waste gas tends to charged by the ions when the gas is flown through created electrical field. Ionization of gas promotes its quick purification. Electrostatic Precipitator is reckoned for its excellent filtration performance, low operating charge, low maintenance cost and minimal downtime.
