Contaminated water flows down through the packing while air flows upward. VOCs or other contaminants are transferred from the contaminated water stream to the air stream, which then flows out through the top of the tower. Clean water flows out at the bottom of the tower. C is the partial pressure or concentration of the VOC dissolved in the liquid.
Air stripping is the process of moving air through contaminated groundwater or surface water in an above-ground treatment system. Air stripping removes chemicals called "volatile organic compounds" or "VOCs. The air passing through contaminated water helps evaporate VOCs faster. After treating the water, the air and chemical vapors are collected, and the vapors are either removed or vented outside if VOC levels are low enough.

Air stripping is a technique in which wastewater and air are intensively brought in contact with each other. This causes the volatile compounds present in wastewater to be transferred into the air. The air containing VOC must be treated in an air treatment system e. The space taken by an air treatment unit varies greatly.
