The Driving Forces for the Business
•Principle of Particulate Scrubbing
•“To entrap the particles in liquid droplets”
•Mechanism:
• a) Collision (impaction) – all sizes•• b)
Electrostatic Forces –small sizes•• c) Brownian Molecular Movements• -ultra-fine sizes

Wet Electrostatic Precipitator
PurposeRemoval of sub-micron particulateand condensed elements, i.e.: heavymetals, dioxin and furans
AirPol Wet Electrostatic Precipitator
Wet Electrostatic Precipitator
Wet ESP Electrodes
Wet ESP Internals
WESP Applications
Combustion processes which producesub-micron elements and / orelements which condense & result in “blue” or “brown” haze stack plume.
Key target elements includeheavy metalsfine “sticky” particulateacid mistscondensed salts
