Answer Posted / a.feroz khan
electrostatic precipitator (ESP), or electrostatic air
cleaner is a particulate collection device that removes
particles from a flowing gas (such as air) using the force
of an induced electrostatic charge. Electrostatic
precipitators are highly efficient filtration devices that
minimally impede the flow of gases through the device, and
can easily remove fine particulate matter such as dust and
smoke from the air stream.[1]. In contrast to wet scrubbers
which apply energy directly to the flowing fluid medium, an
ESP applies energy only to the particulate matter being
collected and therefore is very efficient in its consumption
of energy (in the form of electricity).
