QED Environmental Systems products

EZ-Tray® Air Strippers are sliding tray, stainless steel air strippers used to remove volatile organic compounds (VOC) from groundwater. As Groundwater enters through the top of the air strippers, millions of air bubbles are forced by the blower pressure up through the perforated trays, vigorously aerating the water to a froth and removing volatile contaminants (VOC) as gravity pulls the water down through each tray. This simple, revolutionary technology delivers up to 99% VOC removal, while the low maintenance and easy access cut O & M costs dramatically.

QED makes VOC removal even easier with the EZR Tray Air Stripper. The EZR Tray is a sliding tray, stainless steel air stripper ideal for removing volatile organic compounds (VOCs) and dissolved gases from contaminated groundwater and waste streams. The simplified, snap-together tray design is lighter and more cost effective than other designs. Featuring a patented water flow path design, the EZR Tray allows flow rates of up to 120 gallons per minute; making it easier for smaller models to remove low concentration or easy to strip contaminants. The EZR Tray design provides easier access for process monitoring, inspection and cleaning, saving time and reducing O&M costs. Offering numerous advantages over other air stripping methods, the EZR Tray Air Stripper is the easiest choice for VOC removal.

The innovative design of E-Z Stacker Air Strippers delivers many advantages to environmental consultants, remediation contractors, and end-users. E-Z Stacker models are sized and priced to be the most economical choice for many low to moderate flow cleanup applications (up to 40 GPM). Low capital expense and low O & M requirements make the difference. The unique E-Z Stacker configuration consists of a series of integrally-molded shell/tray modules. The multiple sieve tray design uses forced-draft air bubble generation to provide rapid, effective VOC removal (up to 99%). Every element of the heavy-duty HDPE construction has been engineered for durable, reliable performance with a multi-step positive seal against leakage.

QED chemical metering pumps are suitable for dispensing chemicals for a variety of anti-scaling and anti-foaming applications. These pumps provide precise and adjustable delivery of anti-scale/anti-foam agents. Graco chemical metering/injection pumps deliver flow rates from 17 to 150 gallons per day and operate in -40° F to 175°F (-40°C to 79°C) temperatures. Typical pump feed point is in the E-Z Tray inlet piping, ahead of the stripper. Turbulent tray action quickly ensures complete mixing on the top tray.
