Offering high removal efficiencies and easy maintenance

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

Offering numerous advantages over other air stripping methods, the EZR Tray air stripper 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 to $0.20 per 1,000 gallons of drinking water.

Air stripping with the EZR Tray air stripper is an effective way of removing trihalomethanes (THMs), 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 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 EZR Tray air stripper is also easier to inspect and maintain than other alternatives.

The exclusive self-cleaning vortex action and proprietary finish on internal components dramatically extends service life between cleanings

Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc. (NYSE: GGG), announces the new AutoPump® AP4™ Ultra® Xtreme® pump for the most extreme landfill and remediation pumping applications. The exclusive self-cleaning vortex action and proprietary surface finish on internal components dramatically improves performance, allowing pumps to operate up to 10 times longer than the AP4 Ultra pump between cleanings.

2021 11 09 095806The new AP4 Ultra Xtreme pump utilizes the same unique, non-stick coating and polished metal internal components as the QED AP4 Ultra and Ultra High Temperature pumps with their exclusive AutoPump Xtreme self-cleaning action. 

The combination of the AP4 Ultra coating and the continuous internal scouring of the vortex action also means a reduction of over 50% of time spent cleaning the pump internal components versus the AP4 pump. 

The AutoPump AP4 Ultra Xtreme pump is available as a Short, Bottom Loading pump in either a standard AP4 Ultra or AP4 Ultra High Temperature pump.

PLR device determines leachate and/or condensate levels accurately, safelyand efficiently without the need to break the wells’ vacuum seal

Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc (NYSE: GGG)., announces the release of the Precision Level Reader (PLR), which is a very accurate, safe and efficient method for determining leachate and/or condensate levels in gas wells. 

With QED’s new PLR device, liquid levels are detected within seconds and are recorded with a time, date and location stamp with no need to interrupt the vacuum in the well. Using a permanently installed weight and tube, the PLR engages a micro-compressor and differential sensors to determine a water level reading that is never affected by foam and will not cross-contaminate from well to well.

The PLR device delivers key advantages over other liquid level measurement devices for gas well applications. With no need for a water tape or well seal removal, level readings take a fraction of the time and effort, with no exposure of technicians to dangerous gases or liquids in the process. Levels are taken with the well vacuum intact, meaning no errors occur due to foam in the well or vacuum losses. With average level readings taking only seconds, operators see immediate and long-term labor savings. All readings are displayed immediately and stored electronically for future access. 

2021 09 13 211855

Proven industry-standard materials and manufacturing techniques in the QED PLR device ensure a high quality, durable product. The PLR system consists of three components: the Remote Measurement System (RMS), a handheld portable PC and handset software. An IP65 ABS enclosure houses the air pump, battery, pressure sensor and interface circuits in the RMS. The associated rugged handheld unit features integrated Bluetooth, a Windows 10-based operating system, and a minimum of 64MB RAM and 256MB Flash memory. Finally, the customized interface application software features a user-friendly digital display with audible and visual alerts. The software offers simple data recording and storage options, with the option to display results in either imperial or metric measurements.

Permanent orifice plate kit retainer for fast, accurate wellhead tuning

Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc. (NYSE: GGG), announces upgrades to its industry-leading ORP215M-R precision orifice plate wellhead. The QED ORP215M-R wellhead combines easy plate exchanges for more accurate flow measurement with precise adjustment of gas flow, especially at very low rates (below 10 standard cubic feet per minute). The new design includes a complete kit of six orifice plates securely attached to the wellhead for quick access. A permanent stainless-steel S-type orifice plate retainer keeps the plates close at hand and helps prevent loss of the orifice plates. With plates readily at hand, it is easier to keep gas fields properly tuned for the best performance. 

Changing to the correct orifice plate takes only seconds, with no time wasted shutting down the control valve or retuning the well. The precision fine tune control valve provides exact gas flow control. Unlike traditional valves, this unique design achieves near linear flow adjustment across its entire range. The serviceable control valve includes a stainless-steel rod for long service life. 

2021 08 23 105958The QED ORP215M-R wellhead features heavy-duty engineered plastic construction – tougher and stronger than PVC. Molded, glass-filled polypropylene boosts strength and resistance to UV, weather and harsh field conditions, significantly increasing wellhead durability. A tapered connection makes hose fitting easy, while simpler service saves valuable field time and helps reduce maintenance and labor costs. 

QED’s Easy Port™ fittings are engineered specifically for landfill gas wellheads. Made with fiber-reinforced engineered plastic, they have a screw-on bird-proof cap that seals tightly. The sample ports feature heavy walls to reduce heat loss and freezing, and are UV protected for much longer field life. The cap seals tightly but can be easily removed with a simple twist. It is tethered to the fitting so it cannot be dropped or lost. 

The upgraded ORP215M-R wellhead allows operators to have the exact orifice plate for efficient tuning right at hand. By tuning the ORP wellhead to maintain differential pressure (DP) of 0.5 to 5-inches of water column vacuum, wellheads operate at the optimum rate. When used with the QED GEM5000 portable gas analyzer, technicians can monitor and tune wellheads to match changes in field flow, keeping the optimum DP.
