The ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by a knocking action.

As for the dry ESP, the wet ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by flushing water.

The SIR (Switched Integrated Rectifier) reduces the particulate emission level and improves ESP overall performance without the need of costly extensions. ANDRITZ provides a robust and reliable technology with the highest expertise and service capabilities in air pollution control. ANDRITZ now offers a wide range of its advanced high voltage power supplies for electrostatic precipitators.

The Fabric Filter (or baghouses or bag filters) uses a filter media to separate Particulate Matter (PM) from the flue gases. The Particulate Matter are deposited at the surface of the fabric filter which may be made of different materials depending on the flue gas physical and chemical composition. The dust is removed periodically when cleaning the bags.

Hybrid Filter is a combination of ESP and FF with several configurations (in serie and in the same casing (integrated) or in separated casings in serie or in parallel (separated)).

A bag is more than just a wear part - it is a critical factor in the performance of the filter system. Delivering sustainable Quality for Superior Filter Performance.

ANDRITZ’s clean air technologies engineer – Mr. Jörgen Linnér from the Product Center Växjö (Sweden) – has received the Masuda award from the International Society for Electrostatic Precipitation (ISESP) for developing innovative uses and applications for Electrostatic Precipitator (ESP) technology.
