Air Stripping Description

Air stripping is a mass transfer process in which volatile contaminants in water or soils are evaporated into the air. Organics removal from wastewater via air stripping depends upon temperature, pressure, air-to-water ratio, and surface area available for mass transfer. Air-to-water volumetric ratios may range from 10 : 1 up to 300 : 1. Contaminated off-gas and stripped effluent are the resulting residuals. Volatile hazardous materials must be recaptured for subsequent treatment to preclude air pollution.
