Michaelis GmbH & Co. KG

Wet Electrostatic Precipitator Technology



Wet electrostatic precipitators have been used for many decades for the effective separation of micro-particles and aerosols. Michaelis uses long term operational experiences in the industrial field and offers wet ESP systems with gas flow capacities from 500 Nm3/h upwards. Wet electrostatic precipitators are operated in water-saturated areas, i. e. after quenchers or scrubbers. The high moisture content of the flue gas increases the electrical conductivity. Under this condition even very small particles and aerosols are separated effectively.
