What is the efficiency percentage of electrostatic precipitators?

Electrostatic precipitators are highly efficient air pollution control devices designed to remove particulate matter from gas streams. Their efficiency percentage can often range significantly based on the design, application, and operational conditions, but it is generally recognized that they can achieve efficiencies greater than 95%. This high level of efficiency is mainly due to the principle of electrostatic attraction, where particles are charged and subsequently collected on oppositely charged plates, leading to the effective removal of even fine particulates from contaminated air or gas.

The aforementioned capability to remove a vast majority of particulates, often reaching close to 99% efficiency under optimal operating conditions, is a fundamental advantage of electrostatic precipitators. They are commonly used in industries such as power generation and manufacturing, where strict emission control standards must be met.

In contrast, options suggesting lower efficiencies fail to encompass the remarkable capabilities of electrostatic precipitators, which are engineered to ensure minimal particulate emissions.
