In-Situ Ammonia Removal Of Leachate From Bioreactor Landfills, Nicole Berge
In-Situ Ammonia Removal Of Leachate From Bioreactor Landfills, Nicole Berge
Electronic Theses and Dissertations
A new and promising trend in solid waste management is to operate the landfill as a bioreactor. Bioreactor landfills are controlled systems in which moisture addition and/or air injection are used as enhancements to create a solid waste environment capable of actively degrading the biodegradable organic fraction of the waste. Although there are many advantages associated with bioreactor landfills, some challenges remain. One such challenge is the ammonia-nitrogen concentration found in the leachate. The concentrations of ammonia-nitrogen tend to increase beyond concentrations found in leachate from conventional landfills because recirculating leachate increases the rate of ammonification and results in accumulation …
