An important aspect of generating power from landfill gas is ensuring that methane collection rates meet project goals. The most common cause of reduced methane collection rates is the buildup of liquids in the gas extraction wells and collection system, hindering the easy flow of gas through the system. To address this concern, Brown County has been using both HammerHeadĀ® and AutoPumpĀ® air-powered automatic pumps from ABC member QED for several years to pump leachate and condensate from gas wells to keep the methane flowing at a high rate.
