With this biological scrubber system the biogas is treated by naturally occurring bacteria along a media bed. The bacteria used in treatment have the ability to remove H2S and from the biogas. The biological scrubber system has low operating costs and uses inexpensive materials to sustain the bacterial colony. Currently, cleaned gas is burned at an enclosed flare on site. The City of Quincy is investigating adding a micro turbine to convert the clean natural gas to electrical power.
As part of the project AERG prepared all the design drawings and supported the client in obtaining all applicable State and local permits for the installation of the system.
The newly installed biogas scrubber system includes:
The client contracted AE Resources Group, Inc. (AERG) to design and build a biogas recovery system so that the captured biogas could be safely flared with an option of adding a micro turbine at a later time. AERG contracted and installed a fully-automated, PLC controlled biogas treatment system. AERG also designed and installed a 218,000 square foot HDPE base-liner and floating cover for the anaerobic lagoon.

Quincy, Washington is a town of about 13,000 people near the Columbia River in central Washington. The municipal water treatment in Quincy treats wastewater from commercial and residential sources. The City of Quincy needed a way to treat is anaerobic lagoons in part due to the high load from the food processing plants in town. Their facility contains an onsite wastewater treatment system which treats all the wastewater streams generated by the surrounding areas. The wastewater is initially treated in an anaerobic lagoon followed by an aeration system. The existing anaerobic lagoon is covered with a floating cover system and the captured methane gas was burned in a candle-stick flare.
