Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. READ MORE

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.

Monitoring LFG well flow is the key to maintaining a healthy well field, improving methane production, and staying in compliance. What was once a tedious process has become fast and simple with QED’s Easy Port™ Wellhead Fittings (Patent Pending). READ MORE
November 17, 2014, Ann Arbor, MI – En Novative Technologies is happy to announce they are now part of QED Environmental Systems, Inc. En Novative's market leading, EPA-accepted En Core® Sampler, as well as their other soil sampling tools, are now backed by QED's more than 30 years of experience in developing and delivering quality sampling products.READ MORE
August 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.

Is this Gate Valve Open or Closed? TAKE THE QUIZ
Engineers at QED recently conducted a torque break test comparison between a PVC gate valve and QED’s Precision Fine Tune Control Valve™. READ MORE
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
QED had originally designed its Wellheads to have red port covers. It soon became clear that idea was for the birds. READ MORE
QED’s Well Caps are the first engineered gas well caps that allow liquid level readings without removing the wellhead. This causes less system disruption, makes taking level measurements faster and safer, and landfill technicians are not exposed to gases that may be released from the well. READ MORE
QED has redesigned the collar on the Quick-Change™ Orifice Plate Wellhead (U.S. Patent Number 8,800,597 & Patents Pending) to now have wings. This makes the collar more ergonomic and even easier to turn when making orifice plate changes. READ MORE
There are seven important factors to consider when buying a landfill/remediation pump. QED has you covered when it comes to the best pumps and accessories with expert support and resources. READ MORE
Landfill gas (LFG) wells frequently accumulate leachate and condensate that can greatly reduce the gas collected. Dewatering systems can reduce these liquid levels, increasing gas flow and improving system efficiency. READ MORE
When using traditional landfill gas flow measurement devices it can be difficult to obtain accurate flow readings. Inaccurate flow measurements can lead to an improperly balanced wellfield, resulting in numerous problems including regulatory exceedances. READ MORE
Moving to cutting-edge LFG control technology, one Texas landfill is producing higher-quality gas along with more consistent energy plant operation. READ MORE
Most landfill gas flow measurement devices create differential pressure (DP). The DP reading is then used to calculate flow. Flow readings are highly dependent on the accuracy of the DP reading. READ MORE
QED has upgraded its Fine Tune™ Control Valve (U.S. Patent Number 8,800,597) with glass fiber reinforced polypropylene to add durability and increase the life of the Valve's active components. READ MORE
The Orifice Plate Selector Guide is a handy tool that allows you to quickly determine the best orifice plate size for your application. READ MORE
