QED Highlights E-Z Tray Air Stripper For Removing VOCs From Contaminated Groundwater And Waste Streams

Offering high removal efficiencies and easy maintenance

QED Environmental Systems, a leading manufacturer of innovative environmental products, announces the E-Z Tray Air Stripper, a sliding tray, stainless steel air stripper ideal for removing volatile organic compounds (VOCs) from contaminated groundwater and waste streams. E-Z Tray’s exclusive design results in very high removal efficiencies in an easier-to-maintain process unit.

Offering numerous advantages over other air stripping methods, E-Z Tray provides easy access for process monitoring and inspection, even while in operation. It is less prone to fouling and can be cleaned by one person with a simple pressure wash. It is also less intrusive at a site and offers a wide turn-down range. Typical treatment costs range from $0.10 - $0.20 per 1,000 gallons of drinking water.

Air stripping with E-Z Tray is an effective way of removing trihalomethanes (THMs), which can form in drinking water when disinfectants like chlorine breaks down precursor organic compounds, normally organic solids. As contaminated groundwater enters through the top of the E-Z Tray air stripper, millions of air bubbles are forced by blower pressure up through the perforated trays. This creates a turbulent froth zone with an extremely high air-to-liquid surface area for mass transfer of VOCs from liquid to air. Using the froth instead of a conventional tower packing delivers high VOC removal efficiencies, even under fouling conditions. The EZ-Tray method is also easier to inspect and maintain than other alternatives.
