South Texas Landfill − Case Study


Courtesy of QED Environmental Systems, Inc

During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill.

The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an additional comparison. The screen shot (at right) shows the increase in value of the methane produced at Well 90 resulting from the increase in concentration and flow.
