100% Leak-tested LFG WellheadsLeakTest web

QED understands it is very important that landfill gas systems limit the leakage of air into the collected gas flow. To ensure that QED's LFG wellheads do their part in controlling leaks, we have leak tested 100% of our gas wellheads since early in the products' introduction. READ MORE



High Tech, Non-stick Finishes Reduce Pump Maintenance; Calculator Shows Your Savings

A comparison test at a landfill dealing with high solids showed that new non-stick finishes inside the pump greatly extended the period between servicing. The landfill saved enough money in maintenance costs that they could pay for their new AutoPump® (Patent Pending) AP4 Ultra from QED in 12 months. READ MORE


Case Studies Show QED's New Pump Lowers Maintenance Costs

QED's new AutoPump® AP4 Ultra was tested at multiple landfills across the country, dealing with the most severe applications. These comparison tests show that a landfill in Wisconsin saved enough in maintenance costs to pay for their new Ultra in 10 months, and a landfill in Tennessee recouped the price of their Ultra in just 4 months.

New Landfill Gas System Utilizes QED's Revolutionary LFG Measurement and Control Technology

AliOnSite small"The main advantage, to me, is the Fine Tune™ Control Valve that is used on the QED wellhead − it’s one of those revolutionary things in the landfill gas industry. Gate valves don’t give you very good control unless you always want the valve 100% open and you can apply as much vacuum as possible. But when it comes to low-flow wells then it’s important to be able to balance the field, and with a gate valve you really can’t do that,” said Ali Abedini of Sperling Hansen Associates Inc.

New UV-protected Flex Hose is Changing the Industry

SolarguardAugust 11, 2014, Ann Arbor, MI - QED has revolutionized landfill gas hose with its new Solarguard™ Flex Hose, which is made with UV-resistant flexible PVC with a rigid PVC helix. Accelerated UV tests have proven that this formula allows Solarguard hose to maintain tensile strength and flexibility, so it can last at least twice as long as conventional hoses. And, Solarguard hose will not experience as many cracks and air leaks as standard PVC hose, helping to improve the overall health of your well field.

Solarguard hose fits over 2” and 3” PVC pipe, is available in 5’ and 100’ lengths, and comes in QED’s distinctive yellow color. QED’s all-stainless steel banding coils are uniquely designed to fit Solarguard hose and use high strength, all-stainless steel clamps, which are user friendly, durable, and far less expensive than commonly used plated helical hose clamps.

Case Study: Improved Well Tuning Achieved at a Landfill Gas to Energy Developer's Sites


Morrow Renewables has replaced all their existing wellheads with QED Quick-Change™ Orifice Plate Wellheads in their LFGTE wellfields. This has enabled them to achieve more accurate flow measurements and precise adjustment control, essential for tuning wells effectively. READ THE FULL CASE STUDY

The Advantages of Dedicated Bubbler Tubes for Liquid Level Measurements

dedicated bubbler tubeLandfill technicians commonly use a level meter tape to measure LFG well liquid levels. With this method, they have to shut down the system vacuum, open the wellhead and, after the measurement, reassemble the wellhead. Not only does this take time, but landfill gas is released and the level readings are affected by removing the vacuum; and air is introducted into the collection system. READ MORE

South Texas Landfill Increases Gas Flows and Maintains Regulatory Compliance with Fine Tune Control Valve™

S. Texas Landfill

During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. Well data was tracked for a period of time before and after the installation of the Control Valves, along with data from the closest neighboring well on the same trunk line (that was using a gate valve for flow control) to be used as an additional comparison. All of this well data was compiled into an interesting case study showing how QED products can improve landfill gas flows and help maintain regulatory compliance. READ THE FULL CASE STUDY
