Nitrogen management in bioreactor landfills.
One scenario for long-term nitrogen management in landfills is ex situ nitrification followed by denitrification in the landfill. The objective of this research was to measure the denitrification potential of actively decomposing and well decomposed refuse. A series of 10-l reactors that were actively producing methane were fed 400 mg NO3-N /l every 48 h for periods of 19-59 days. Up to 29 nitr...
متن کاملBioreactor landfills : Do they work ?
This paper begins by providing an outline of various waste stabilisation techniques on which the concept of bioreactor or process-based landfills is based, followed by an overview of the research and development of this alternative landfill approach. The paper then presents a summary of the Australian experience. It also reports on the current state of bioreactor landfills and discusses the dif...
متن کاملPractice review of five bioreactor/recirculation landfills.
Five landfills were analyzed to provide a perspective of current practice and technical issues that differentiate bioreactor and recirculation landfills in North America from conventional landfills. The bioreactor and recirculation landfills were found to function in much the same manner as conventional landfills, with designs similar to established standards for waste containment facilities. L...
متن کاملThe Fate of Nitrogen in Bioreactor Landfills
Although bioreactor landfills have many advantages associated with them, challenges remain, including the persistence of ammonia-nitrogen in the leachate. It has been suggested that ammonia-nitrogen is one of the most significant long-term pollution problem in landfills and is likely a parameter that will determine when landfill postclosure monitoring may end. The fate of nitrogen in bioreactor...
متن کاملModeling of leachate recirculation using vertical wells in bioreactor landfills.
Leachate recirculation (LR) in municipal solid waste (MSW) landfills operated as bioreactors offers significant economic and environmental benefits. The subsurface application method of vertical wells is one of the most common LR techniques. The objective of this study was to develop a novel two-dimensional model of leachate recirculation using vertical wells. This novel method can describe lea...
