Biofiltration of methane from cow barns: Effects of climatic conditions and packing bed media acclimatization
(2018)
Abstract: The performance of biofiltration to mitigate CH4 emissions from cow barns was investigated in the laboratory using two flow-through columns constructed with an acclimatized packed bed media composed of inexpensive ...
Methodology to determine the extent of anaerobic digestion, composting and CH4 oxidation in a landfill environment
(2018)
Abstract: An examination of the processes contributing to the production of landfill greenhouse gas (GHG) emissions is required, as the actual level to which waste degrades anaerobically and aerobically beneath covers has ...
A simple field method to qualify the state of saturation in capillary barriers
(2005)
Abstract: A simple and straightforward field method to rapidly qualify the state of saturation of moisture retaining layers (MRL) is proposed
and the details of its calibration and operation, described. The technique is ...
Can soil gas profiles be used to assess microbial CH4 oxidation in landfill covers?
(2011)
Abstract: A method is proposed to estimate CH(4) oxidation efficiency in landfill covers, biowindows or biofilters from soil gas profile data. The approach assumes that the shift in the ratio of CO(2) to CH(4) in the gas ...
Modeling methane migration and oxidation in landfill cover materials with TOUGH2-LGM
(2009)
Abstract: Methane oxidation within a Passive Methane Oxidation Barrier (PMOB) and the downward migration of molecular O2, whose presence is necessary for the oxidation reaction to occur, were simulated using the finite ...
Assessment of the design of an experimental cover with capillary barrier effect using 4 years of field data
(2011)
Abstract: One important step in the design of inclined covers with capillary barrier effect (CCBE) is the determination of the water diversion length (DL). Numerical simulations can predict the DL more precisely than ...
Effect of composts, nitrogen salts and NPK fertilizers on methane oxidation potential at different temperatures
Other titre : Effects of compost, nitrogen salts and fertilizers on methanotrophic activity
(2012)
Abstract: The effects of compost, nitrogen salts, and nitrogen-phosphorous-potassium (NPK) fertilizers on the methane oxidation potential (MOP) of landfill cover soil at various temperatures were assessed. For this, we ...
Evaluating methane oxidation efficiencies in experimental landfill biocovers by mass balance and carbon stable isotopes
(2012)
Abstract: Biocovers are an alternative for mitigating fugitive and residual emissions of methane from landfills. In this study, we evaluated the performance of two experimental passive methane oxidation biocovers (PMOBs) ...
Evaluation of methane oxidation in a landfill cover material using a simple indicator approach
(2011)
Abstract: Estimates of methane (CH4) oxidation rates (Rg) in biocovers are
crucial for development of abatement strategies. Rg values were estimated
in a landfill biocover with a simple approach based on gas diffusion ...
Methanotrophs and methanotrophic activity in engineered landfill biocovers
(2009)
Abstract: The dynamics and changes in the potential activity and community structure of methanotrophs in landfill covers, as a function of time and depth were investigated. A passive methane oxidation biocover (PMOB-1) was ...
