(a) Name any two places where it is essential to install electrostatic percipitators. Why is it required to do so?
(b) Mention one limitation of the electrostatic precipitator.
(a) Two places where it is essential to install electrostatic precipitators are automobile vehicles and thermal power plants. This is so because these produce toxic gases and need an electrostatic precipitator to remove particulate matter from their exhaust.
(b) One of the major limitations of the electrostatic precipitator is that it cannot remove particulate matter that are very small particles that are less than 2.5-micrometre in diameter). The PM 2.5 or smaller are the one which causes various respiratory problems and can pose the greatest harm to human health.
