What are the unique design, operational, and regulatory issues associated with bioreactors?
Leachate Recirculation – A bioreactor requires a large amount of leachate and supplemental liquid to be distributed evenly throughout the waste mass. The design and operation of leachate recirculation systems requires careful attention so that the system can meet this operational requirement without disrupting landfill operations or causing other leachate management problems. Landfill Gas Management – The increased LFG generation over a reduced time period that comes with a bioreactor presents both opportunities and challenges. Design, installation, and operation of an active LFG collection system will be an essential component of any bioreactor operation. Successful operation of an LFG collection system under wet landfill conditions is difficult, particularly with the potential odor and Clean Air Act compliance issues at stake. Geotechnical Stability – The addition of large amounts of liquid in a landfill bioreactor changes the geotechnical characteristics of the waste mass and requir
