2. Electrostatic precipitation: Separation of particles or droplets suspended in a gas or air. A large potential difference ($$12$$ to $$30\ \text{kV}$$ dc) is required between the spaced electrodes in the precipitator. The charged particles are attracted to an electrode of opposite charge and collected.
