Air stripping

It is an environmental engineering technology used for the purification of groundwaters and wastewaters containing volatile compounds.

Volatile compounds have relatively high vapor pressure and low aqueous solubility characterized by the compound's Henry's law coefficient, which is the ratio of the concentration in air that is in equilibrium with its concentration in water.

Pollutants with relatively high Henry's Law coefficients can be economically stripped from water.

Water that reaches the bottom of the system is typically considered treated, but additional testing may be done to determine if it is safe for consumption.

Though, some towers can be transported on a movable trailer to be used in different areas where water treatment is needed.

A natural draft is used for removing more volatile substances such as hydrogen sulfide, radon, or vinyl chloride.

[1] Though, other studies suggest that it can take far longer depending on the type of and concentration of substance.
