QED offers EZR Tray for removing VOC25 October 2022
QED Environmental Systems has launched a stainless steel tray sliding air stripper suitable for removing volatile organic compounds (VOC) from contaminated groundwater and waste streams.
The EZR Tray air stripper is expected to result in high removal efficiencies in a process unit.
Air stripping with the EZR Tray air stripper is a way of removing trihalomethanes, which can form in drinking water when disinfectants like chlorine break down precursor organic compounds, normally organic solids. As contaminated groundwater enters through the top of the EZR Tray air stripper, millions of air bubbles are forced by blower pressure up through the perforated trays. This creates a turbulent froth zone with a high air to liquid surface area for the mass transfer of VOCs from liquid to air. Using the froth instead of a conventional tower packing is said to deliver high VOC removal efficiencies, even under fouling conditions.
The EZR Tray air stripper is claimed to provide easy access for process monitoring and inspection, even while in operation. It can be cleaned by one person with a pressure wash and offers a wide turn-down range. Typical treatment costs range from $0.10 to $0.20 per 1,000 gallons of drinking water.
