The Wet Electrostatic precipitator separates liquid particles and aerosols from the raw gas stream by charging the particles in an electric field and depositing them on the inner surface of the collector tubes. The collected droplets coalesce into larger drops and drain by gravity to a liquid collection tank located at the base of the unit. Main features separation of liquid and solid particles for particle sizes below 0,5 micron suitable for gas temperatures up to 100°C low capital and operating costs high availability material of construction will vary according to raw gas composition: steel, stainless steel, lead, polypropylene, FRP modular construction, plant capacity up to 50.000 m³/h per module specific energy consumption of 0,3 to 0,6 Watt per m³ of gas.
