Techniques of Air Pollution Control
Adsorption – In this technique, the polluted air is passed through porous solid adsorbents kept in suitable containers. The gaseous pollutants are adsorbed at the surface of the porous solid, and clean air passes through. Gravity – In this process, the particulate settles down by the action of gravitational force and gets removed.

Electrostatic Precipitator
Electrostatic precipitators (ESPs; Figure 6.9), or electrostatic air cleaners, are particulate collection devices that remove particles from a flowing gas (such as air) using the force of an induced electrostatic charge.To produce the free ions and electric field, high internal voltages are required. ESPs are highly efficient filtration devices that minimally impede …

Gravitational Settling
Gravitational settling is, as has been noted, one of the most efficient means of separating solids from surrounding liquid. Solid/liquid separation can be achieved this way as long as the solids are more dense than the liquid. 3 Simple settling is, however, affected by other forces in certain circumstances. Particles settle in one of three general ways:

Gravity settling chambers for controlling air pollution
The length of the chamber determines the amount of time the particles remain at the reduced rate.This starving of the gas's forward motion allows the particles sufficient time to settle out into the hoppers. The collection efficiency of settling chambers varies as a function of particle size and settling chamber design.
