Filtration and Separation
Efficient dedusting of flue and exhaust gas with GEA´s reliable filtration and separation systems.
GEA is a reliable partner for gas cleaning solutions in nearly all areas of production. To ensure air pollution control, gas cleaning systems are essential components in your process chain.
The GEA technologies impress with their low energy consumption and minimal maintenance requirements.
GEA offers different separation or filtration technologies for the removal of particles. The following emission control devices are usually used for the dedusting of flue gases:
- Fabric Filters
- Ceramic Candle Filters for hot gas filtration
- Electrostatic Precipitators
- Wet Scrubbers
Stricter emission requirements made it necessary to reduce particulate emissions to less than 10 mg/m³. With the use of surface-active filter media and regeneration of the filter elements with low pressure, GEA offers the ECOpuls system for the best performance and lowest operating costs.
Special industrial applications request the dedusting at temperatures up to 500°C. The GEA ceramic candle filter offers efficient removal of particulates and with BisCat design the simultaneous removal of acid gases and NOx.
Electrostatic Precipitators are used in flue gas cleaning to capture particulate pollutants through electrostatic attraction. For the most part, Dry ESP are used in flue gas cleaning while Wet ESP are especially suitable for the flue gas purification of chemical processes, cleaning gases saturated with water vapor.
In a wet scrubber, a gas stream is brought into contact with a liquid stream in order to absorb components of the gas stream in the liquid. The components of the gas stream can be solids, liquids or gases. Gas scrubbers can be used simultaneously for dedusting and for the separation of harmful pollutants.

Bagfilter (ECOpuls)
Bagfilters are the technology of choice in many cases when low dust content is needed for gas cleaning. Their ability to remove large Ioads on a non-selective basis has made them important for many applications.
Ceramic candle filter
GEA high-temperature filters with ceramic elements to remove particulate matter and acidic gases. With very low dust emissions and thermally stable under high operating temperatures. No cooling of flue gases are required and no thermal heat energy is wasted when implementing them.
Customized multi-stage gas scrubber systems
Exhaust from industrial processes often require cooling, dedusting or removal of gaseous pollutants. In many cases, scrubbers are of advantage for these duties.
Electrostatic precipitator (dry and wet)
GEA has been building electrostatic precipitators for cleaning industrial process for over many years. Well over 12.000 units have been supplied to firms all over the world. Being the air pollution control technology supplier of choice, GEA offers innovative system designs, state-of-the-art microprocessor controls and constantly upgrades and rebu...
