Stripping columns are used to remove unwanted materials from process streams. The air stripping column shown below is used to remove ammonia from water and wastewater feedstreams. This section describes various types of air stripping columns as well as steam strippers.
Addressing environmental degradation and ensuring environmental sustainability are inextricably linked to all methods of reducing volatile organic compounds VOCs from the environment. A packed column air stripper is a typical example of such technologies for the removal of VOCs from polluted water. The present review is devoted to the applications of a packed column air stripper and, in comparison with previous reviews, presents further elaborations and new information on topics such as modeling and simulation of the dynamic behavior of the air stripping process in a packed column air stripper.

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.
August QED Environmental Systems. The E-Z Tray air stripper photo is a sliding-tray, stainless-steel air stripper used for removing volatile organic compounds VOCs from contaminated groundwater and waste streams.
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.
Air stripping involves the mass transfer of volatile contaminants from water to air. For ground water remediation, this process is typically conducted in a packed tower or an aeration tank. The typical packed tower air stripper includes a spray nozzle at the top of the tower to distribute contaminated water over the packing in the column, a fan to force air countercurrent to the water flow, and a sump at the bottom of the tower to collect decontaminated water.
