An air stripper is used to transfer volatile organic compounds (VOCs) from a groundwater stream to an air stream which is then either treated and discharged, or simply discharged. Air is passed up through a number of perforated trays, while the contaminated groundwater enters the top of the air stripper and cascades down from one tray level to the next. The turbulence in the water caused by the pressurized air effects the mass transfer of VOCs. The air is supplied to the air stripper using a pressure blower.
MLE Equipment uses two different types of air stripper: the EZ-Stacker, composed of molded plastic trays that stack together, designed for low to moderate flows, and EZ-Tray, a stainless steel shell with slide-out trays, designed for low to high flows. Both models are manufactured by QED Environmental Systems. The advantages of these two models are many, and include small footprint, high VOC-removal efficiencies, and ease of cleaning and maintenance.
The EZ-Stacker and EZ-Tray models of air stripper come in a number of sizes accommodating a wide range of water flow rates. A modeling program is available to make selection quick and easy.
Please see the provided specification sheets and manuals for more detailed information on air strippers.
