Evolution of biodegradation of deinking by-products used as alternative cover material
Abstract: Deinking by-products (DBP) have been used as alternative material for the construction of cover systems for municipal waste disposal facilities and acid-producing mine residues. Considering the high organic ...
Design of inclined covers with capillary barrier effect
Abstract: A design procedure is proposed to minimize water infiltration into landfills in optimizing the water diversion length of inclined covers with capillary barrier effect (CCBE). This design procedure aims at ...
Environmental, geotechnical and hydraulic behaviour of a cellulose-rich by-product used as alternative cover material
Abstract: Deinking by-product (DBP), a cellulose-rich by-product produced in the early stages of the paper recycling process, has been used as alternative material for the construction of cover systems for municipal waste ...
Determination of the hydraulic conductivity function of a highly compressible material based on tests with saturated samples
Abstract: An alternative procedure to determine the hydraulic conductivity function (k-function) based on relationships between saturated hydraulic conductivity and void ratio and between air-entry value and void ratio ...
Influence of capillary barrier effect on biogas distribution at the base of passive methane oxidation biosystems: Parametric study
Abstract: The efficiency of methane oxidation in passive methane oxidation biosystems (PMOBs) is influenced by, among other things, the intensity and distribution of the CH4 loading at the base of the methane oxidation ...
Landfill gas distribution at the base of passive methane oxidation biosystems: Transient state analysis of several configurations
Abstract: The design process of passive methane oxidation biosystems needs to include design criteria that account for the effect of unsaturated hydraulic behavior on landfill gas migration, in particular, restrictions to ...
Does vegetation affect the methane oxidation efficiency of passive biosystems?
Abstract: It is often reported in the technical literature that the presence of vegetation improves the methane oxidation efficiency of biosystems; however, the phenomena involved and biosystem performance results are still ...
A simple field method to qualify the state of saturation in capillary barriers
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 ...
Causal model to describe the spatial and temporal variation of faecal coliform concentrations in a pilot-scale test consisting of ponds aligned in series
Other titre : Causal model to describe the variation of faecal coliform concentrations in a pilot-scale test consisting of ponds aligned in series
Abstract: In this study, the application of path analysis was tested to validate a causal model developed to verify the influence on several factors of the variation of faecal coliform concentration in pilot-scale ponds ...
Dynamics and diversity of methanotrophs within an experimental landfill cover
Other titre : Diversity and dynamics of methanotrophs within an experimental landfill cover soil
Abstract: Three experimental biocovers were installed during the summer of 2006 at the St‐Nicéphore landfill in Québec (Canada). The main objectives of the experimental program were to assess the efficiency of these biocovers ...
