Bioreactor Technology

The controlled injection of leachate into the anaerobic bioreactor stimulates the formation of methane by providing the required moisture and feedback for microbial growth. The innovative design and operation strategies implemented by Jones Edmunds have helped overcome the challenges that many designers and operators experience with most bioreactors. The principal components of a successful anaerobic bioreactor design are described below:

Wells
A bioreactor incorporates both horizontal and vertical extraction and/or injection wells.  Leachate is injected under pressure into a well, and gas is extracted.  The combination of horizontal and vertical wells allows the operator to adjust the injection and extraction to maximize the degradation rate of the waste.


Piping System
The extraction and injection piping systems are designed in loops with cross-connections, flow control balancing valves, and flow meters similar to those used at the well heads.  Where possible, injection piping is piggybacked onto larger-diameter extraction piping to minimize the number of pipe supports and reduce construction costs.

Pumps and Blowers
Blowers and fans develop the negative pressures required for the safe extraction of the landfill gas.
